Looking for a hydraulic gear pump? We offer extensive access to a vast range of hydraulic manufacturers from around the world…
The technical team here at Hydraulics Online have more than 75 years’ combined experience between them, so don’t worry if you don’t know what you’re looking for, or can’t identify an existing pump that you’re trying to replace. Leave that to us. And with our ISO 9001 accreditation, you can relax knowing that you’re in capable hands.
Large or small, a hydraulic gear pump is a simple and economical pump that creates pressure through the meshing of the gear teeth, forcing fluid around the gears to pressurize the outlet side. They may be quite loud during operation, but modern gear pumps are hugely dependable and much quieter than their older counterparts.
A hydraulic gear pump can be found in a variety of hydraulic systems. They have few moving parts, work effortlessly, and operate easily even with pressures of up to 250 bar. The displacement chambers are located between the housing of the pump and the rotating gear wheel.
There are two main types of hydraulic gear pump…
External gear pumps – These pumps are typically found in industrial and mobile applications, e.g. log splitters and lifts. Some of the features of this pump include:
- High working pressures;
- Variety of speeds;
- Large temperature and viscosity range (i.e. flexibility);
- Low cost.
Internal gear pumps – These pumps are used predominantly in non-mobile applications e.g. machine tools and presses or fork-lifts. Key features of the internal gear pump include:
- Low flow pulsation;
- Decreased operating noise;
- High efficiency.
As we said, if you’re not sure what sort of pump would be suitable for your application that’s no problem for our technical team; we are always up for a challenge and can usually work miracles with unrecognisable or seemingly obsolete hydraulic pumps and equipment too. We also undertake hydraulic pump repairs and refurbishment and can often offer “direct equivalents” where it is more cost-effective to do so.
