PVE47QIR122C21V1721

The PVE47QIR122C21V1721 pump belongs to the Vickers Piston Pumps series and supplies controlled hydraulic power in automated machinery. It uses a pressure-compensator control to keep outlet pressure constant under varying loads, which supports stable actuator motion. A fixed displacement of 6.0 in³ per revolution establishes the volume moved each shaft turn, while a flow rating of 47 US gpm at 1800 rpm meets medium-capacity circuit requirements. Power is transmitted through a straight keyed Type 1 input shaft that aligns with standard motor couplings, and right-hand (clockwise) shaft rotation matches common drive arrangements.

Design number 22 marks the internal configuration of this model for users who track revisions in multi-pump systems. The compensator can be set as high as 250 bar (3625 psi) so the unit can support circuits requiring elevated working pressure. A built-in load-sensing function trims displacement automatically to match demand, improving efficiency when full flow is not needed. The pump requires hydraulic fluid filtered to ISO 19/15 or cleaner to minimize wear on moving parts. Port connections follow a 4-bolt flange pattern, providing a rigid, leak-resistant interface with manifold blocks or hose assemblies.
