Solid Shaft Hydraulic Pumps

Solid shaft hydraulic pumps are Annovi Reverberi N-version triplex units built for installations that connect the pump to its hydraulic motor through a bell housing and flexible coupling rather than a rigid flange. The solid keyed shaft gives system builders complete freedom in motor selection — pair the pump with any hydraulic motor whose shaft and mount match your chosen coupling hardware, using AR’s bell housing kits to maintain alignment.

This architecture suits custom skids, engineered OEM systems, and repowers where the motor is already specified or where a flexible coupling is preferred for vibration isolation and serviceability. A coupled installation lets you replace either the pump or motor independently without disturbing the other component, which simplifies long-term maintenance on high-value industrial equipment.

The category spans replacement-class units through 40 GPM RTD industrial pumps, with each listing showing flow, pressure, rated RPM, shaft dimensions, and required drive power. If you would rather skip the coupling hardware entirely, our direct drive hydraulic pumps mount straight onto splined motors, and complete pump and motor packages arrive pre-assembled. Call WSHPWR for help specifying solid shaft hydraulic pumps and the matching bell housing for your build.
