Typical equipment
Not every machine in this industry uses hydraulics, and equipment architectures vary. Identify the particular hydraulic function before comparing pump configurations.
What the hydraulic system does
Mobile hydraulic systems can power cylinders and motors for work functions. A machine may use several circuits with different requirements; a pump serving an auxiliary function is not automatically suitable for the main working circuit.
Illustrative sequence only; the actual machine cycle and control system may differ.
What matters when selecting a pump?
Cylinder and hydraulic motor work functions · Changing loads, speeds and circuit demands
Main working circuit or auxiliary?
Identify the circuit served by the original pump. Main implement, steering and auxiliary circuits can require different pump designs and controls.
Which control system is installed?
Provide the circuit information and full model suffix. A fixed-displacement pump is not a substitute for a variable-displacement unit merely because calculated flow is similar.
How is the pump driven?
Record the shaft connection, available speed range, rotation and mounting arrangement. Photographs support identification but do not establish dimensional compatibility.
- Identify the exact machine function and circuit type.
- State operating speed range and mounting constraints.
- Confirm shaft connection, rotation and port configuration.
Use the equipment specification to establish the operating envelope. Then review the exact pump model, mounting, shaft, rotation and ports. Ask for clarification where the model code or application requirements are incomplete.
From the application to a pump specification
Use flow, pressure, speed and installation requirements to shortlist a product. An industry name alone is not a selection rule.
Prepare a useful technical enquiry
Send the equipment model, pump nameplate and function served by the pump. Describe whether the enquiry covers the main circuit or an auxiliary circuit.
Include the required quantity, destination and delivery expectations. For a replacement, add the old pump’s nameplate and photographs of the installation.
