Hydraulic Component Replacement & Cross-Reference

Prepare the details needed to identify a replacement hydraulic pump, valve, motor or cylinder. Compare function and interfaces before confirming an equivalent.

Prepare your replacement enquiry

Known details are enough to start. You can add photographs and drawings by email after preparing the enquiry.

If the code is unreadable, state “unknown” and describe the component.

Pressure, flow, speed, displacement, force, fluid or temperature. Include units.

Flange, shaft, rotation, ports, dimensions, valve symbol, coil voltage or control.

This prepares an enquiry; it does not send a message. Enter contact details and submit on the next page. Send photos or drawings to info@impex-connect.com.

How to select a replacement hydraulic component

A matching pressure rating or similar model name is only the start. A hydraulic replacement must also match the function, interfaces, controls and operating conditions. Use the technical enquiry below to request a pump, valve, motor or cylinder replacement.

What information is needed for a hydraulic cross-reference?

Component Key checks
Pump Full code, displacement, rotation viewed from shaft end, flange, shaft, ports, pressure, speed and control.
Hydraulic motor Displacement, torque, speed, continuous pressure, shaft and flange, drain requirements, brake and port arrangement.
Valve Full code, hydraulic symbol, mounting interface, spool function, normal position, flow, pressure, coil voltage and connector.
Cylinder Bore, rod, stroke, retracted/extended mounting dimensions, mounting type, loads, ports, seals and working pressure.

Include clear nameplate photographs and dimensional drawings. Photos show identification details; they do not by themselves confirm internal function or compatibility.

How we describe a proposed replacement

Direct replacement — after verification

Relevant hydraulic, mechanical and electrical requirements have been checked. Availability and final specification still need confirmation.

Replacement requiring changes

The proposed alternative may require adapters, pipework, electrical changes or control adjustments. Those differences must be stated before ordering.

Where information is incomplete, the selection remains subject to additional verification. This page does not provide an automatic database of confirmed equivalents.

Frequently asked questions

Is the same displacement enough to replace a pump?

No. Rotation, shaft, mounting, port layout, speed and pressure ratings, inlet conditions and controls must also be checked.

Can a valve with the same mounting pattern be substituted?

The mounting interface alone is insufficient. Verify the spool symbol, normal and transition states, pressure/flow limits and electrical actuation.
