External gear pumps reviewed by displacement, flange, shaft and ports.
Request gear pumps review: Send the complete model code, quantity, destination and a clear nameplate photo. We will identify the remaining confirmation points.
Gear Pumps Selection Guide
Displacement and pressure
Displacement sets theoretical flow per revolution; pressure rating and duty determine whether the pump suits the system.
Rotation and construction
Confirm clockwise, counter-clockwise or reversible duty, plus aluminum, cast-iron or other housing requirements.
Flange, shaft and ports
Pilot diameter, bolt pattern, shaft form and port threads must be checked from drawings or measured evidence.
What Must Be Reviewed
Pump type and displacement
Confirm from the original code, datasheet, nameplate, drawing, or measured part as applicable.
Working and peak pressure
Confirm from the original code, datasheet, nameplate, drawing, or measured part as applicable.
Control or compensator type
Confirm from the original code, datasheet, nameplate, drawing, or measured part as applicable.
Rotation direction
Confirm from the original code, datasheet, nameplate, drawing, or measured part as applicable.
Mounting flange
Confirm from the original code, datasheet, nameplate, drawing, or measured part as applicable.
Drive shaft and spline
Confirm from the original code, datasheet, nameplate, drawing, or measured part as applicable.
Port position and thread
Confirm from the original code, datasheet, nameplate, drawing, or measured part as applicable.
Through-drive and auxiliary options
Confirm from the original code, datasheet, nameplate, drawing, or measured part as applicable.
Typical Applications
- Industrial power units

Reference Brands
Names are used for identification only. No affiliation or authorization is implied.
Required Confirmation
- Provide the complete model code and nameplate photo.
- Confirm clockwise or counter-clockwise rotation as viewed from the shaft.
- Share flange, shaft and port photos or dimensions.
- State the application, pressure, fluid and replacement reason.
Important: A functional alternative may still require customer review of dimensions, connectors, ports, or system settings. Known differences are stated in the quotation.
Frequently Asked Questions
How do I identify a replacement hydraulic gear pump?
Provide the complete code, displacement, rotation, flange, shaft, port size and position, pressure, speed and application.
Can a gear pump with the same displacement fit directly?
Not necessarily. Rotation, pressure rating, mounting flange, shaft and ports can differ even when displacement is identical.
How is hydraulic gear pump price confirmed?
Price is quoted for the exact displacement, construction, interfaces, quantity, inspection scope and destination.
