The Royal Shakespeare Company might be used to performances raising the roof, but it came to Hydraulics Online when it needed to be able to lift the stage…
The Royal Shakespeare Company’s Stratford-upon-Avon theatres play host to more than one million visitors each year – all drawn by its breath-taking family Christmas shows, innovative productions and workshops and the finest theatre productions of Shakespeare’s plays in the world.
Nobody could beat Hydraulics Online on price. (Gill Leefe, Control Systems Engineer, RSC.)
When the Royal Shakespeare Company staged Wendy and Peter Pan in its Royal Shakespeare Theatre in 2013 and 2015, the whole team wanted to create a magical, beautiful experience for its family audiences.
Control Systems for Heavy Lifting
Gill Leefe is Control Systems Engineer at the RSC in Stratford and was responsible for the control of the hydraulic system. Gill says: “There are important safety considerations when using hydraulic equipment and we have to be very careful, but they can be very useful in the theatre. We do have our own mains power system for the hydraulics and we make use of them when there are big, heavy things to move.”
For the production of Wendy and Peter Pan, the hydraulics were used to move large pieces of set, to startling effect.
Gill explains: “While Wendy is looking for the lost boys, the stage begins to rise, revealing Tinkerbell underneath. In the space the elevated stage creates, another piece of set rises to reveal the hidey-hole where the Lost Boys live and eleven boys dancing on the set.”
The two separate controllers were linked together to a central control panel. With one actor strapped to one element of the moving set and more rising with the second moving element of the set, it was vital that the hydraulic systems were in perfect working order and fully safety tested.
“Sometimes I operated that show,” says Gill, “and from where I sat I could see the front row of kids. When the stage began to lift up they would jump out of their seats, wondering what was going on. Then I could see the expressions of wonder on their faces; they were really excited. It was an absolutely brilliant moment.”
The equipment was reused in 2016 at London’s Barbican theatre in the production of King Lear starring Antony Sher – following which it was returned to Stratford upon Avon for reconditioning. Gill needed to replace the Dual Driver Multi-Function Proportional Valve and a quick online search showed that Hydraulics Online could help.
“The team at Hydraulics Online were really efficient and friendly,” says Gill. “Sometimes we are not the easiest people to deal with because we can generate a lot of paperwork; taking on a new supplier can be a lengthy process for us, but Hydraulics Online worked very quickly and made it really easy for us.”
Hydraulics Online are very efficient and pleasant to deal with. (Gill Leefe, Control Systems Engineer, RSC.)
The pain of setting up a new supplier did prompt Gill to check with existing suppliers as to whether they could supply a suitable part. Gill explains: “I did call around looking for alternative quotes, but nobody could match Hydraulics Online on price.”
The part arrived in good time, ahead of the stated lead time, and Gill says she was very impressed with the service: “Hydraulics Online were very efficient and pleasant to deal with throughout and their price is the best. I will definitely be using Hydraulics Online again and would recommend them,” she comments.
The equipment is now ready to be used in the theatre to help to bring some future RSC magic to audiences.

Back to our new customer down in Antarctica…
When we say we trade the world over, we aren’t joking! A recent enquiry came from a new customer in Antarctica, who sent the team a photo of a hydraulic pump. Not knowing what they wanted and with the identification plate missing from the unit, the team were tasked with finding out what type of hydraulic pump it was. We never back away from a challenge!
Surely enough, the team identified the pump as a Denison P Series tandem pump and were able to quote on a seal kit to needed to undertake some important repairs on the pump; the pump came from a pristine environment into which the unit had been leaking – a repair was essential.
But sometimes a repair may just not be feasible, providing poor or unreliable performance at best. If this is what we find, we will always contact you to explain why and to quote for a brand new replacement pump.
There are a huge range of manufacturers from around the world, designing and making a variety of hydraulic pumps including: gear pumps, rotary vane pumps, fixed displacement / screw pumps, bent axis piston pumps, axial piston pumps, radial piston pumps. As well as offering pumps from all the major brands, we also offer direct equivalents to some of the more well-known hydraulic pump manufacturers… particularly useful if you’re up against tight deadlines, timescales or budgets.

They enable individual hydraulic solutions for nominal flow up due to a large variety of poppets, springs and covers, including shuttle valves, stroke limiters, solenoid valves and position control.
Parker Hydraulic Sequence Valves: Parker’s sequence valves are used to control the sequence of operation of two or more hydraulic actuators. The sequence valve pressure is set higher than the first actuator operation pressure. Once the first actuator has completed its cycle, the sequence valve opens, allowing the second actuator to move. Parker’s line of pilot-operated sequence valves include a series of internally piloted, externally drained valves and a series of externally piloted, internally vented valves.
Parker Hydraulic Spool Valves: Parker’s sequence valves are used to control the sequence of operation of two or more hydraulic actuators. The sequence valve pressure is set higher than the first actuator operation pressure. Once the first actuator has completed its cycle, the sequence valve opens, allowing the second actuator to move. Parker’s line of pilot-operated sequence valves include a series of internally piloted, externally drained valves and a series of externally piloted, internally vented valves.
Parker is only one of many brands that we supply; have a look at some of the hydraulic valves that we regularly supply by hopping over to our catalogue. If you’d like to make an enquiry or are simply looking for more information, then call us to speak to one of our friendly technical team or you can enquire online.
In the meantime, we’ll just leave this here; it’s just one of dozens of testimonials we have that you can see:
Thank you for your email and receipt for the hydraulic valve we ordered. I was very pleased with the prompt service received… very efficient and helpful in identifying the correct part we needed. We will most definitely use your company again.
With our competitive access to a vast range of hydraulic equipment manufacturers and over 75 years’ technical experience behind us, it’s hardly surprising that our customer base covers such a vast range of industries and applications all over the world for Parker pumps…
In fact if you named a market or country, we’re confident that we’ll be able to tell you about a customer or project that we’ve been involved with. We do, however, seem to attract a great deal of custom from marine, ship management and offshore services companies. Take, for example, the case of this overseas company looking for a Parker pump for one of their vessels…
The company, whose vessels are used in offshore operations for one of the largest oil producers in the world, first contacted Hydraulic Online when they needed a number of Parker pumps – Denison T6C Series vane pumps – for one of their vessels.
Denison Hydraulics is part of the Parker Hannifin group, and as such a leading industrial manufacturer who provides highly engineered hydraulic fluid power systems and hydraulic equipment that can be found in a multitude of applications ranging from: mobile equipment used in the construction, demolition, agricultural, mining and utilities industries to machinery found in industrial manufacturing and marine equipment for commercial and military ships alike.
Denison vane pumps remain operational at pressures exceeding 4,500 pounds per square inch, differ in size from 0.35 cubic inches to 16 cubic inches, and in displacement from 1 to 250 gallons per minute. These Parker pumps, considered to be some of the toughest components in the industry, are often recognised by their distinctive double-lip design, where the vane is in contact with the cam ring at two points as opposed to one, which is the single-lip design. This double-lip design decreases the vulnerability to contamination when compared to single-lip pumps.
You can find more information on the full range of Commercial Hydraulics Parker pumps by clicking here.
Anyway, back to our customer… we quoted for the T6 Parker Pumps (and some Veljan vane pumps as well), apparently beating off competition from another overseas supplier local to our customer. And the rest is history…
But it doesn’t stop there… the customer was so impressed with our service, that they immediately asked us to quote for a replacement double servo pump that to be used on the bow thruster system on another one of their vessels. Thrusters are mounted to the bow of the vessel to make docking easier; they enable the ship to turn to port or starboard side, without having to use the main propulsion mechanism which involves some forward motion for turning.
As is often the case, the customer sent in a photo (shown here) and asked our technical team to identify their existing pump (Commercial Hydraulics P31 series, Parker pumps) and quote for a replacement unit… which we did. The customer received their replacement pumps within a week of placing their order and quickly had the vessel back servicing oil rigs in the North Sea!
Our customers really are our best advocates, and we have plenty more case studies and testimonials, if you would like to take a look… Maybe your story might feature in our growing library one day too?
Even before becoming part of the Parker Group, Commercial Hydraulics was thought of as one of the world’s biggest names in gear pump manufacturing. And now with the Parker name behind them, Commercial Hydraulics continue to lead the way – the Parker gear pump series regularly referred to as the industry standard against which others are measured.
A Parker gear pump is still made to the same demanding standards set by Commercial Hydraulics – the only difference being that the old Commercial product codes are now preceded by “PG” (for Parker Group).
The Parker gear pump / motor range comprises:
- P30, M30, PGP30, PGM30, P31, M31, PGP031, PGM031;
- P50, M50, PGP050, PGM050, P51, M51, PGP051, PGM051;
- P75, PGP075, PGM075, P76, PGP076, PGM076.
Designed for high-torque applications, the P30, P31, P50, P51, P75, P76 Parker gear pump series offer a wide variety of drive shafts, with unique pressure-balanced thrust plates contributing to optimal performance. Manufactured with hi-tensile grey iron, such a Parker gear pump can be supplied in single and multiple section configurations, with a choice of (relief) valve options.
- P315, PGP315, PGM315;
- P330, PGP330, PGM330;
- P350, PGP350, PGM350;
- P365, PGP365, PGM365.
The PGP / PGM 300 Parker gear pump series delivers superior reliability and performance in even the most demanding of heavy-duty hydraulic applications. The three-piece cast iron construction with large area, low-friction bushings means that this Parker gear pump series provides strength, high efficiency, and long life in severe operating environments. The design includes an advanced thrust plate and seal configuration, which optimizes performance even in high temperature and low viscosity conditions.
Here at Hydraulics Online, we know that time and money are precious commodities, and that in a “real time” world that never sleeps, you can often find yourself needing something “yesterday” … with a budget under pressure to stretch ever further. Again. That’s why we also offer a range of completely interchangeable, direct equivalents to the Commercial Parker gear pump range. Built and tested here in the UK, you can be assured of a quality product that can more often than not be dispatched within 24 hours.
Our experienced technical sales team are a lovely bunch and will be more than happy to advise you on Commercial / Parker gear pumps if you are looking for more help and technical guidance… Or even a miracle!
And in the meantime we’ll close with this unsolicited “thank you” from a new customer, received after they took delivery of their Parker P76 gear pump. They have since ordered another to hold as a spare:
I write to thank you for your assistance in delivering a replacement Parker tandem pump for our vessel “Adeline”. The pump was installed on the main engine reduction gearbox this morning and has been successfully tested in all operating modes. Your help was much appreciated, good weekend to you and your team.
Technical Director – Worldwide ship management services company.

As an ISO 9001 accredited company, we are resolutely committed to quality and continuous improvement – that extends to only ever supplying top quality hydraulic equipment and components. We simply won’t put our name to anything less. Ever.
We are proud to export Parker Hannifin hydraulics globally…
It’s genuinely hard to think of an industry, market or corner of the world where we haven’t been involved to date – You name it, we’ll have done it! Our competitive pricing and deliveries are backed by over 75 years’ combined technical experience, or in the words of a customer:
… you don’t just shift boxes, you know your business inside out.
As a quick example of a Parker Hannifin enquiry that we’ve handled in the past, a UK-based ship maintenance and services company, contacted our technical team about a Parker Hannifin Commercial Hydraulics P365 Series pump. After quoting on the unit we also provided a quote on a “direct equivalent” with a lower cost and quicker lead time.
The equivalent P365 pump is a quality, British product which offers identical features and performance to the original Commercial Hydraulics pump. The customer ordered the direct equivalent and took delivery sooner than later – with leftover cash to spare!
We like a challenge…
You guys really helped me out last time I was stuck (was how an email from a returning customer began recently, and it continued)… I apologise for the lack of available details.
The email came from a worldwide marine engineering and underwater services provider, the email itself having been written by the Ship Superintendent of a vessel that was “struggling as one of her Linear Cable Engines has developed a serious problem and is now out of action.” Challenge accepted!
Our technical team have a reputation for consistently providing practical, trusted advice and solutions backed up by an ability to deliver – supplying both well-known and niche products – even against the most challenging of timescales and budgets. In this particular case, within 24 hours our team had worked with the small amount of information available to identify and quote the equipment required – a Denison Hydraulics electrohydraulic stroker (S23-12413-0, EHS 5A* with deadband) to suit a Denison Gold Cup pump, type P14P. Another happy customer!
Our catalogue showcases a range of the hydraulic products that we regularly supply all over the world. It is only a small sample, however – we couldn’t possibly include everything that we do.
If you’d like to get in touch, you can enquire online, send our team an email via: firstname.lastname@example.org, or call us to talk things through – whether that’s on Parker Hannifin hydraulics or something seemingly obscure, obsolete – or even “impossible”!
Parker are one of the most prominent players in the hydraulics industry, offering motion and control technologies and systems for a range of applications in the commercial, mobile, industrial and aerospace markets. Parker’s range includes: hydraulic accumulators, hydraulic cartridge valves, hydraulic controls, hydraulic filters, hydraulic pumps and motors, hydraulic systems, hydraulic valves, hydraulic cylinders, hose and accessories.
With operating pressures up to 420 Bar (5000 psi) and speeds up to 3000 rpm, the heavy-duty Parker PV series axial piston pump (PVplus, pictured) has a robust design that provides circuit reliability for the most demanding of industrial applications. It is available in displacements from 16-360cc for operating pressure up to 420 Bar.
Other features and benefits of Parker PV series axial piston pumps (PVplus pumps) include:
- Compact, service-friendly design with flexible mounting interface;
- Quiet operation;
- High operating efficiency for lower power consumption and reduced heat generation;
- Simple hydraulic controls with “no-leak” adjustments;
- High self-priming speed capabilities;
- Modular compensators with fast response;
- FEM optimized housing and pre-compression chamber resulting in low output, pulsation and less noise to insulate.
With quality in-demand products, lead times can sometimes become protracted creating a challenge for end users and original equipment manufacturers alike. But here at Hydraulics Online we like a challenge…
As an example, a company specialising in the design and manufacture of heat exchangers contacted our technical team requiring 5 Parker PV Series axial piston pumps on a quick delivery time. They had already contacted a number of other hydraulic suppliers, only to be consistently told that delivery times would be 8-10 weeks. We tried harder…
Our technical sales team have a wealth of knowledge between them, over 75 years to be precise, and don’t like to be beaten. And they weren’t. We were able to quote the 5 Parker axial piston pumps that the customer needed on a much reduced 5 week lead time. And, as an ISO 9001 accredited company we consistently deliver against our promises and do what we say we’re going to do. The result? Another very happy customer who took delivery of his Parker PVplus pumps in just over half the time that he had originally been led to believe would be possible.
We export to over 150 countries worldwide – technology and extensive carrier networks actually make the world a very small place – and in addition to Parker PV series axial piston pumps, we supply a huge range of other hydraulic pumps including: gear pumps, rotary vane pumps, fixed displacement pumps / screw pumps, bent axis piston pumps, axial piston pumps and radial piston pumps. If you’re up against particularly tight deadlines or budgets, we can often offer quality, direct equivalents to well-known hydraulic brands, then there’s our hydraulic repair service offering an alternative cost-effective solution for you.
If you’re not sure on what sort of hydraulic pump you need, our experienced technical team can help determine the one that will be best suited to your application. As we’ve shown, we’re always up for a challenge and can usually work miracles with seemingly obsolete hydraulic pumps too! Our catalogue showcases some of the hydraulic pumps, and other products, that we regularly supply – but it really is just a sample, so if you can’t find what you’re looking for then we’re confident that we’ll still be able to help.
Looking for a Parker hydraulic pump? We export worldwide.
Parker Hydraulics are undoubtedly one of the world’s leading hydraulic manufacturers of motion and control technologies with an extensive product range – click here for more information. But if a Parker hydraulic pump is what you’re looking for, then we have it covered here – so stay a while and read on!
Known for their durability and functionality, a Parker hydraulic pump will perform in even the toughest of environments and applications. The range comprises: tandem, gerotor, gear, screw, hydrostatic transmission, axial piston, gear and vane pumps. We’ll look at each Parker hydraulic pump briefly now:
Parker tandem piston pump:
Parker’s HP2 Series consists of two independently controlled over-centre piston pumps on a single drive shaft. Housed in a compact reservoir with a filter and associated valving, the typical input speed is 3600 rpm with an intermittent pressure of 2600 psi.
Parker Gerotor pump:
The Parker QPM3 Gerotor Pump is a low pressure pump for high efficiency (up to 10 bar, flow rate from 20 to 80 L/min), while the GPP2 High Speed/Low Torque (HSLT) design (pictured) provides speeds to 5000 RPM and continuous pressure to 2000 PSI. Aluminium construction offers optimum power to weight ratio.
Parker bent axis piston pumps:
F1/F2 fixed displacement bent-axis truck pumps, F11 small frame and F12 large frame fixed displacement bent-axis pumps and motors, T1 fixed displacement axial piston pumps truck applications, T12 dual displacement bent-axis motors, VP1 load sensing truck pump, V12 small frame and V14 large frame variable displacement bent-axis motors. F11 and F12 VOAC pumps are bent axis, fixed displacement heavy duty motor/pump series.
Parker GR screw pump:
Offering a long service life and quiet operation, Parker GR screw pumps are dependable, economical low pressure pumps free from pulsations. These rotary pumps with axial flow have only three moving parts and can be installed in any position, as well as above oil level. The secondary screws act as seals and are turned hydraulically by the fluid being pumped. There is only a rolling action between the main screw and the secondary screws, which eliminates noise and vibration.
A number of other brands come under the Parker banner too; the Parker hydraulic pumps range actually also includes “Commercial Hydraulics” and “Denison Hydraulics” pumps.
The Commercial Parker hydraulic pump range…
Commercial Hydraulics are now part of the Parker Group, with the Commercial Parker hydraulic pump series often referred to as the industry standard against which all others are measured. Previously branded Commercial pumps, motors and flow dividers are still made to the same exacting standards by Parker; the only difference is that the previous Commercial product codes are now preceded by “PG” (Parker Group).

We can dispatch a Parker hydraulic pump to anywhere in the world, but as with many other major brands, we can also often offer quality direct equivalents. And as a far as an equivalent to a Commercial Parker hydraulic pump is concerned, our units are built here in the UK… a quality product that we more often than not can dispatch within 24 hours.
The Denison Parker hydraulic pump range…
So, that’s a quick overview of the Parker hydraulic pump range; if you’d like more information and guidance then just get in touch with one of our lovely technical engineers. They’d love to hear from you! And we have plenty of happy customers who are glad that they did – take a look in our testimonials library to see for yourself.
Looking for a Parker vane pump – a Parker T6, T67 or T7 series pump? Needing one quickly… within a handful of days, rather than weeks? We can sort that for you.
I am most satisfied with your service and I am going to send you all enquiries that we get on hydraulic pumps and parts!
Prevention is better than cure. Fact. And in an ideal world, if your system did break down or start to fail, you would simply source your pre-identified “critical spares” from stock – with no drama, no fuss and minimal impact on production and service level agreements. But life’s never quite that straight forward, is it?
Well, it can come something close if you at least know where to go to get hold of spares that you needed “yesterday”… if you know an ISO 9001 accredited supplier who isn’t phased by a challenge and has a proven ability to “come up trumps”! Like supplying that replacement Parker vane pump for example…
I am thoroughly impressed with the service offered to us… The hydraulic pumps were supplied in the extremely quick turnaround time of 24 hours and collected by our own courier.
If you have no time to spare in getting your hands on a Parker T6, T67 or T7 series vane pump, then why not get in touch with us now? You can contact the team via: +44 (0)845 644 3640, email@example.com, through our enquiry form or our online chat service (bottom right) – we’ll still receive your message even if we’re offline!
Parker T6, T67 and T7 series vane pumps have been designed specially for high or low circuits. With a variety of different cartridges in double and triple pumps, the vane pump allows low flow at high pressure (300 bar max.) and high flow at lower pressure. This allows enhancement in your circuit design and allow a very fast pressure cycle change with a very precise flow. Other features and benefits of the Parker T6, T67 and T7 series include the:
- pumps’ ability to reach a pressure of up to 4650 PSI, meaning that fitting costs are lessened and it delivers prolonged life at reduced pressure;
- high volumetric efficiency, typically better than 94%, which reduces heat generation and allows speeds down to 600 RPM at full pressure;
- high mechanical efficiency, typically better than 94%, which reduces energy consumption;
- wide speed range (600 RPM at 3600 RPM) which, combined with large size cartridge displacements, improves operation for the lowest noise level;
- low speed (600 RPM), low pressure, high viscosity (3900 SUS) allowing an application to run in cold environments with little energy consumption and without risk of seizure;
- low ripple pressure (± 29 PSI) lessening piping noise and increasing lifetime of other components in the circuit;
- greater resistance to particle contamination with increased pump life, due to the double lip vane;
- diverse range of options (cam displacement, shaft, porting) allowing for a customised installation;
- improved the low noise level features;
- high performance functionality and durability even in the toughest environments including: commercial, mobile, industrial and aerospace applications.
Need more help or information? Our hydraulic engineers have over 60 years’ experience in hydraulic systems design and component supply, and are well-placed to decipher which hydraulic pump is best for your application. We supply a huge range including: gear pumps, rotary vane pumps, fixed displacement pumps / screw pumps, bent axis piston pumps, axial piston pumps and radial piston pumps from leading and lesser-known, niche hydraulic equipment manufacturers from around the world. But if it is Parker that you are looking for then we have more information on their pumps (and the rest of their product range), here:
One last thing, that “critical spares analysis” we mentioned at the beginning: an analysis of system critical hydraulic components and recommended spares, so that you can understand which of your hydraulic components are most susceptible to failure and the impact that this may have on safety, production and systems performance… and just as importantly the cost and lead times involved in sourcing replacements. Is that worth giving some thought?
As a trusted hydraulic motor supplier we offer extensive, competitive access to big name, and less well-known, manufacturers from around the world…
That’s because a branded hydraulic motor can often be directly interchanged with those from smaller, niche hydraulic motor manufacturers… meaning that if timescales or budgets are not in your favour, then we can be!
We should perhaps just add that “less well-known” never means inferior quality; we refuse to compromise on that. Our ISO 9001 accreditation, means that we believe that the service and products you receive should be second-to-none, and that includes our hydraulic motor range.
The Hydraulics Online team are passionate about anything and everything hydraulic – but we don’t expect you to be! So if you don’t know what hydraulic motor you are looking for then it doesn’t matter, that’s what we’re here for. Our technical team will work with whatever information you do have, or even a photograph, if you are looking to replace an existing hydraulic motor.
And according to our customers we “know our stuff”:
“Just to let you know how impressed I am with your service. Not only did you recognise the hydraulic motor I needed, where others had failed to, but you were able to despatch a replacement to me incredibly quickly.”
We can supply a vast range of motors including: radial piston motors, axial piston motors, external gear motors, Gerotor and Geroler motors from manufacturers including: Bosch Rexroth, Denison, Italgroup, Maxma, Parker, Roquet, Sauer Danfoss, Vickers and White Drive Products.
So, let’s bring all this to life and showcase a handful of the thousands of customers we’ve helped to date…
Take the case of the owner of an offshore fishing vessel, that was stranded, unable to operate… every lost hour meant more lost revenue. Ouch! The Hydraulics Online team knew that the existing brand of hydraulic motor was on an uncomfortably long lead time, and instead sourced an “off the shelf” equivalent motor which was flown into the UK within 48 hours. No re-engineering was required and the loss to our customer’s revenue was minimised.
Moving on, a power transmission engineering company approached our technical team after one of their blue-chip clients reported a failure on a critical gearbox / hydraulic motor. Our customer had been unable to source a replacement from their existing suppliers within an acceptable lead time; solving the problem and delivering a high level of service to their client was crucial. Our team identified the hydraulic motor immediately and a replacement identical hydraulic motor was purchased and air-freighted within 48 hours again to minimise downtime for the end customer.
A third customer, a national household power generation company, needed a replacement hydraulic motor following the failure of the main hydraulic starter (radial piston) motor on a LM6000 GT package. The original unit was a Bosch-Rexroth hydraulic motor and was on a long lead time. One of our hydraulic engineers visited the site within an hour of contact, identified the hydraulic motor and specified a suitable equivalent replacement Italgroup hydraulic motor, available from Hydraulics Online stock. This was delivered to site the same day, minimising downtime and getting the company up and running again.
“Hydraulic motor arrived this morning, it’s now fitted and our machinery is working perfectly. Thanks for your help in identifying what we needed… I will certainly recommend your service to all my contacts.”
Our catalogue shows a sample of some of the more popular hydraulic motors that we regularly supply, but it is only a sample – it’s impossible for us to list everything that we do! So if you can’t find the hydraulic motor that you’re looking for, or aren’t even sure what you need, then complete our Stock Enquiry Form or for more technical advice contact one of our experienced technical team on: +44 (0)845 644 3640 or via: firstname.lastname@example.org.
And if we still haven’t convinced you to give us a try, then maybe reading more of our customer testimonials would do it? Go on, let us take the pressure!
