Hydraulic Gear Pump – FAQ

What is an external gear pump?

An external gear pump is a positive-displacement hydraulic pump that uses two externally meshing gears to deliver stable hydraulic flow.

What applications are external gear pumps commonly used for?

External gear pumps are widely used in construction machinery, agricultural equipment, industrial hydraulic systems, material handling, and mobile hydraulics.

What pressure range can an external gear pump handle?

Most external gear pumps operate at rated pressures up to 200–250 bar, with higher peak pressure depending on design and materials.

What displacement ranges are available?

External gear pumps are available in a wide range of displacements, typically from 1 cc/rev to over 100 cc/rev, depending on series and configuration.

What speed range is suitable for external gear pumps?

Typical operating speed ranges from 500 to 3000 RPM, depending on load conditions, oil viscosity, and pump design.

Can external gear pumps be customized?

Yes. External gear pumps can be customized in terms of displacement, pressure rating, shaft type, mounting flange, port size, and rotation direction.

Are external gear pumps interchangeable with OEM brands like Rexroth?

Many external gear pumps are designed to be dimensionally interchangeable with major OEM brands such as Rexroth, Danfoss, Eaton, and Parker.

What materials are used for external gear pumps?

Common materials include aluminum alloy housings for lightweight applications and cast iron housings for higher pressure and heavy-duty use.

What hydraulic fluids can be used?

External gear pumps are compatible with mineral hydraulic oils, HLP/HV oils, and other standard industrial hydraulic fluids.

How do I select the right external gear pump?

Selection depends on pressure rating, displacement, speed range, application requirements, and installation dimensions. Contact our engineers for technical support.
