Parker Gear Pump

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.

Parker Commercial Hydraulics

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:

Parker gear pump P30 P50 P75

  • 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.

Parker Gear Pump P315 P330 P350 P365

  • 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!

Parker gear pump P76And 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:

Dear Ian,

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.

Hydraulic Pump Repair

Searching for a hydraulic pump repair service? Look no further…

Just a quick email to thank you for the hydraulic pump repair. My neighbour is really grateful; he said that without the repair the machine would have just been “ferraille” (scrap). Guess I owe you a bottle of red!

When new customers ask what services we can offer, we keep it simple and say: “If it’s hydraulic we can design it, supply it, solve it or repair it…” That means that if you’re looking for a hydraulic pump repair service, then your search is over!

As with other hydraulic equipment, many of our well-repaired and refurbished hydraulic pumps are virtually indistinguishable to a brand new unit. Our service includes a free evaluation – having examined your existing pump to diagnose the extent of work needed, and ability to recover and re-use existing components.

When evaluating your hydraulic pump our team could offer recommendations to improve its design and productivity, so that you could reduce running costs and minimise the likelihood of any future downtime and hydraulic pump repair work. Our assessment may determine that a hydraulic pump repair is not feasible, not good value for money or simply not recommended. If this is the case then we will quote for a new, replacement new unit in addition to quoting for your hydraulic pump repair if appropriate.

Let’s give you a quick example to bring all this hydraulic pump repair talk to life: Our technical team received a phone call from a well-known, global oil company asking whether we could fix one of the pumps (a Parker, Commercial Intertech P15H 6 Section pump) in their system. We asked to see a quick photograph of the defective pump first, before confirming that, yes, we could undertake the repair. The pictures below show the pump, “before” and “after”… Not a bad looking makeover is it?

Hydraulic Pump RepairIf a repair isn’t possible, or not what we would recommend, we may be able to offer a “direct equivalent” to your existing brand of hydraulic pump. This can be a particularly attractive option if you are up against tight timescales or budgets… but rest assured, it doesn’t mean compromising on quality. Ever. As an ISO 9001 accredited company, quality means everything to us. We want you to be able to “fit and forget” any equipment that we supply aside from undertaking routine servicing and maintenance, obviously.

Hydraulic Pump Repair

Take the case of another large offshore oil company, who contacted the team looking for a Commercial Hydraulics P365/P330 tandem pump; they needed one urgently as they were in a breakdown situation on one of their accommodation rigs. The bad news was that the original Commercial Hydraulics pump was on an 18 week lead time, so that simply wasn’t an option for the customer. However, the good news was that we could offer a direct equivalent (pictured) to be supplied from stock… a quality product, constructed and tested in the UK. The customer placed their order instantly. Within 24 hours the pump had been assembled, tested and dispatched… before being flown to the accommodation rig by helicopter the very next day.

At Hydraulics Online we can offer direct equivalents to a vast range of hydraulic manufacturers. We’re always up for a challenge, and even if components are discontinued or seemingly obsolete, we can more often than not source an equivalent suitable to your application.

Some of the popular hydraulic pump manufacturers and brands that we can supply include: Adan, Atos, Bosch Rexroth, Breuninghaus, Bucher, Casappa hydraulic pumps, Commercial, Continental, Dowty hydraulic pump, Dynapower, Eaton, Eaton Vickers, Hamworthy, Hydromatik, Kawasaki, Linde, Parker, Permco, Poclain hydraulic pumps, Racine, RHL, Sauer Danfoss hydraulic pumps, Sauer Sundstrand, Salami hydraulic pumps, Tyrone, Uchida, Vickers and White hydraulic pumps.

We supply a variety of hydraulic pump types including: Gear pumps, rotary vane pumps, fixed displacement pumps / screw pumps, bent axis piston pumps, axial piston pumps, and radial piston pumps. We can help identify the pump that will be appropriate for your application, even if you’re not certain on what type of hydraulic pump you need.

So back to that hydraulic pump repair you were looking for. If you’ve read this far then you’re hopefully tempted to give us a try. So what are you waiting for? We promise you, your brand is in safe hands.

Commercial Triple Gear Pump

Here at Hydraulics Online, our sales and technical team are regularly tasked with finding the proverbial needle in the haystack; sourcing obsolete or discontinued hydraulic components, or swapping original hydraulic equipment into modern, off-the-shelf standard products, with minimal, if any, re-engineering.

And we regularly have customers who cannot confirm what they actually need us to supply… identification plates and serial numbers on old hydraulic equipment are often worn away or buried in years of dirt, making it seemingly impossible to identify what is underneath and inside!

However, thanks to the wonders of technology, and in particular smart phones, we haven’t been beaten yet. All our technical team need is a photo or two to work with…

A long-standing overseas customer contacted the team with a series of pictures of a triple gear pump that had originally been fitted to a Coles 1986 crane. They knew nothing more.

Triple Gear Pump

The team were able to identify the unit, a Commercial Hydraulics triple gear pump, straight away and as well as quoting on a replacement unit, they also quoted on a quality, direct equivalent that was available ex-stock. Needless to say the customer ordered the direct equivalent unit: a British-assembled cast iron gear triple pump, pictured here.

You can find more information on Commercial Hydraulics cast iron gear pumps and motors (PGP / PGM 030 / 050 / 075 / 300 / 315 / 330 / 350 / 365 series) here, or you can hop over to our catalogue to view some of the hydraulic pumps and cast iron gear pumps that we regularly supply.

Parker Commercial Hydraulics P365 Pump

A new customer, a UK-based ship maintenance and services company, enquired about a Commercial Hydraulics P365 Series pump. After quoting on the unit we also offered to quote on a “direct equivalent” with a keener cost and lead time.

The equivalent P365 pump (picture here) is a quality, British product offering the same features and performance as the original Commercial hydraulics pump. Needless to say, the customer ordered the direct equivalent and took delivery sooner than later – with money to spare!

We are frequently tasked with finding the proverbial needle in the haystack; sourcing seemingly obsolete or discontinued hydraulic components, or swapping original hydraulic equipment into modern, off-the-shelf standard products, with minimal, if any, re-engineering. Offering direct equivalents as an alternative, or sometimes even the only option, is an every day occurrence… And as the customer the choice is always yours as to whether or not you accept!

Case Study: Commercial Hydraulics Pumps

At Hydraulics Online we have extensive, competitive access to both leading and lesser-known hydraulic pump manufacturers from all other the world – including Commercial Hydraulics pumps.

Having peace of mind is key when buying any hydraulic equipment; you want to be able to “fit and forget”. We also understand that sometimes you actually needed something “yesterday” and that your budget is always being asked to stretch that… little… bit… further.

That’s why we offer a range of completely interchangeable, direct equivalents to the Commercial Hydraulics pumps 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. So, even if you’re literally stranded on a vessel out at sea, we can take the pressure!

Commercial Hydraulics Pump 2 Staying close to home, a company who supply spare parts for the mining, construction, cement, oil and gas industries enquired about a direct equivalent to a Commercial Hydraulics P51 pump. They had bought a similar pump from us about six weeks previously and their customer was more than happy with its performance. Like the original Commercial Hydraulics P51 pump, the direct equivalent (pictured here) has a priority flow divider.

Other features of the Commercial Hydraulics P51 pump (and the equivalent) include: speeds of up to 2400 rpm and pressures up to 3000 psi (206 bar) and output flows reaching up to 66 gpm (250 lpm). The PGM050 (and equivalent) pump has an average torque of up to 1720 in-lbs (2016 kg-cm) at 2000 psi (137 bar) while the PGM051 (and equiavlent) pump has an average torque of up to 2250 in-lbs (2592 kg-cm) at 2500 psi (172 bar). Optional priority, two-speed, and unloader valves are available.

Commercial Hydraulics Pumps 2Travelling a little further afield, a large offshore oil company recently enquired about a Commercial Hydraulics P365 / P330 tandem pump; there was no time to spare as there was a breakdown on one of their accommodation rigs. The Commercial Hydraulics pumps were on an 18 week lead time, not the news the customer wanted to hear, however, we were able to offer a direct equivalent (pictured here) from stock… a quality product, built and tested here in the UK. The customer placed their order instantly and the pump was dispatched within 24 hours.

Some of the features of the Commercial Hydraulics P365 pump (and the direct equivalent) include: speeds ranging between 900-2400 rpm and fluid displacements up to 9.0 cir (147.5 ccr). It maintains a continuous pressure up to 3500 psi (241 bar) with intermittent pressures up to 4000 psi (275 bar) and has output flows of up to 90.7 gpm (343.3 lpm). The motor torque ranges from 1705-3740 in-lbs (1964-4308 kg-cm) at 2400 rpm. It also includes high strength, one-piece integral shafts.

Features of the Commercial Hydraulics P330 pump features include: Speeds from 900-3000 rpm; Fluid displacements up to 3.94 cir (64.6 ccr); continuous pressures up to 3500 psi (241 bar) with intermittent pressures up to 4000 psi (275 bar); Output flows up to 50.1 gpm (190 lpm); Motor torque from 980-1685 in-lbs (1129-1941 kg-cm) at 3000 rpm; High strength one-piece integral shafts.

Commercial Hydraulic Pump 3So, one last example… a UK-based ship maintenance and supplies company enquired after a Commercial Hydraulics P365 Series pump. After quoting on the original Commercial Hydraulics P365 unit, we also offered to quote on the “direct equivalent” with its keener cost and lead time.

Again, the P365 equivalent (pictured here) is a quality, British product offering the same features and performance as the original Commercial Hydraulics pump; it reaches speeds between 900-2400 rpm and has fluid displacements up to 9.0 cir (147.5 ccr) and maintains a continuous pressure of up to 3500 psi (241 bar) with intermittent pressures up to 4000 psi (275 bar). Output flows reach up to 90.7 gpm (343.3 lpm) and motor torque ranges between 1705-3740 in-lbs (1964-4308 kg-cm) at 2400 rpm. This pump also includes a high strength one-piece integral shaft. Needless to say, the customer ordered the direct equivalent and took delivery sooner than he had hoped possible, with money to spare!

Click here if you would like to find out more about the Commercial Hydraulics pumps range, or contact one of the team if you would like to find more about the time and cost savings you can make by taking a direct equivalent instead. The choice is yours.

We can supply the following Commercial Hydraulics pumps and our British-built direct equivalents: P30, M30, PGP030, PGM030,  P31, M31, PGP031, PGM031, P50, M50, PGP050, PGM050, P51, M51, PGP051, PGM051, P75, PGP075, PGM075, P76, PGP076, PGM076, P315, PGP315, PGM315, P330, PGP330, PGM330, P350, PGP350, PGM350, P365, PGP365 and not forgetting the PGM 365.

Case Study: Offshore and Marine Hydraulic Services

The Hydraulics Online sales and technical team are definitely proving that they know their stuff as far as marine hydraulics and offshore applications are concerned; an increasing number of businesses are looking our way to source marine and offshore hydraulic equipment… and often they are up against incredibly tight deadlines too, i.e. they really needed it “yesterday”!

Earlier this week, a large offshore oil company enquired about a Commercial Hydraulics P365/P330 tandem pump – they were in a breakdown situation on one of their accommodation rigs. The Commercial pumps were on an 18 week lead time, not the news the customer wanted to hear, but the good news was that we could offer a direct equivalent (pictured here)  from stock… a quality product, built and tested here in the UK. The customer placed their order immediately. The pump was built, tested and ready for dispatch within 24 hours… to be transported by helicopter to its new home on the accommodation rig the following day.

Some of the features of the Commercial Hydraulics P365 pump (and the direct equivalent) include:

  • Speeds ranging between 900-2400 rpm;
  • Fluid displacements up to 9.0 cir (147.5 ccr);
  • Continuous pressures up to 3500 psi (241 bar) with intermittent pressures up to 4000 psi (275 bar);
