Eckerle EIPS – Segment Pump (Radially Compensated, Reversible, Axially Compensable)

The EIPS series is a crescent‑type internal gear pump with spring‑loaded segments that provide radial compensation. It offers near‑gapless sealing, optional axial compensation and can be configured for reversible operation.

Eckerle EIPR – Circular Pump (Radially and Axially Compensated, No Segments)

The EIPR series uses a compensation ring instead of segments. This design provides low‑friction “roll‑gliding” sealing and very quiet operation. Axial discs maintain axial gap compensation.

Eckerle EIPC – Medium‑Pressure Pump (Radially Compensated, Reversible, Axially Compensable)

The EIPC series is a medium‑pressure version of Eckerle’s segment pump technology. It provides stable performance across the full speed range and can be specified for reversible operation.

Eckerle EIPH – High‑Pressure Pump (Radially Compensated, Reversible, Axially Compensable)

The EIPH series is designed for high‑pressure hydraulic systems. It maintains tight sealing and consistent volumetric efficiency under demanding load conditions.

What types of pumps does Eckerle manufacture?

Eckerle specialises in gap‑compensated internal gear pumps. Their main product families are the EIPS, EIPR, EIPC and EIPH series.

Where are Eckerle pumps used?

They are used in forklift trucks, agricultural machinery, construction equipment, truck tail lifts, injection moulding machines, press brakes, shearing machines and other hydraulic systems.

What is gap compensation?

Gap compensation refers to the radial and axial sealing methods used inside the pump. These systems maintain tight internal clearances, which improves efficiency, reduces leakage and supports low‑noise operation.

Are Eckerle pumps reversible?

Some Eckerle pump series can be specified in a symmetrical design that allows operation in either direction. This applies to the EIPS, EIPC and EIPH series when configured accordingly.

Do Eckerle pumps support energy recovery?

Yes. Eckerle mobile hydraulic systems can feed energy back during motor operation.

What is the maximum pressure Eckerle industrial pumps can handle?

Eckerle industrial pumps can reach peak pressures up to 400 bar.

Can Eckerle replace pumps originally supplied by other manufacturers?

Yes. Many pumps previously supplied under OEM licensing agreements can still be sourced directly from Eckerle.

Can Hydraulics Online help identify an Eckerle pump?

Yes. We can identify pumps from part numbers, application details or photographs, and we can advise on suitable replacements or alternatives.

Can you supply Eckerle hydraulic pumps worldwide?

Yes. Hydraulics Online ships Eckerle products globally with full export documentation and technical support. We’re the only official Export Champion in the UK hydraulics industry, serving 130+ countries since 2004.

Q: Eckerle EIPQ Internal Gear Pumps (Reversible)

Optimized for self-priming applications and low system pressures or high speeds, the EIPQ can operate in both directions of rotation as a pump or as a motor. In addition, the inflow side can also be charged with pressure in pump operation. This results in very high potential for energy savings.

Hydraulics Online Product Knowledge: Eckerle Internal Gear Pumps for Mobile and Industrial Applications

Eckerle specialises in high‑performance internal gear pumps designed for applications where efficiency, low noise and long service life are essential. Their pumps maintain tight internal sealing through radial and axial compensation systems, which support smooth, low‑pulsation flow across the full speed range.

Recognised worldwide for its expertise in designing and manufacturing, Eckerele gap‑compensated internal gear pumps can be found hard at work in a wide range of both mobile and industrial hydraulic systems.

The company’s engineering capabilities have led to long‑standing licensing and supply agreements with major global manufacturers, and they continue to offer direct replacements for many of the pumps originally produced under these partnerships.

Eckerle Pump Series Overview – For Industrial and Mobile Hydraulics

Eckerle internal gear pumps are suitable for stationary industrial systems where consistent performance, long service life and low noise levels are essential. Likewise, Eckerle pumps are suited to mobile machinery that must operate reliably across varying speeds and load conditions.

Key characteristics: very low noise levels; suitable for single or multi-pump combinations; long service life due to robust construction; peak pressure capability up to 400 bar; excellent controllability, including use in speed-controlled servo drives.
Typical industrial applications include presses, injection moulding machines, shearing and forming equipment and industrial power units.
Common applications include forklift trucks, agricultural machinery, construction equipment, utility vehicles and tail-lift systems
