PVE47Q1R122C21V1721

The PVE47Q1R122C21V1721 piston pump belongs to the Vickers Piston Pumps series and is intended to supply controlled fluid power in hydraulic automation systems. Its displacement of 6.0 in³ per revolution establishes the volume moved with each shaft turn and sets the basis for circuit sizing. When the drive speed is 1800 rpm, the pump delivers a rated flow of 47 gallons per minute, supplying actuators that require steady medium-range throughput. Right-hand clockwise rotation ensures direct coupling with engines or motors that follow the same direction. To preserve internal clearances and extend service life, operating fluid must be maintained at ISO 19/15 cleanliness or cleaner.

The pump uses a pressure compensator control, so outlet pressure is limited automatically when the set point is reached, preventing excess energy loss and heat generation. Load sensing is enabled, allowing the unit to trim flow in response to downstream pressure changes and maintain a constant pressure differential across control valves. Connection interfaces follow the SAE 4-bolt flange standard, simplifying installation with widely available manifolds and hoses. A single shaft seal is fitted to block external leakage while keeping the front end design compact; because only one sealing lip contacts the shaft, friction remains low and maintenance procedures are straightforward.
