The PVH098R01AJ30A070000001001AB010A piston pump belongs to the PVH and PVE Open-Circuit Piston Pumps series and is manufactured by Vickers for hydraulic automation systems that need variable displacement flow. With a displacement of 98.3 cm³ per revolution, it supplies a predictable volume to downstream actuators. The unit is rated for continuous service at 250 bar (3625 psi), allowing it to drive high-pressure circuits. A pressure compensator control keeps outlet pressure stable, and the compensator is factory set to 70 bar (1015 psi) so the swashplate reduces stroke once that level is reached. Under a 5 in Hg inlet vacuum the pump operates safely at 1500 rpm, while a zero-inlet condition permits speeds up to 1800 rpm for greater power density. Right-hand clockwise rotation matches common engine drives, and a 4-bolt SAE C mounting flange aligns with standard hydraulic power take-offs.
The input shaft measures 1.25 in, providing compatibility with typical splined or keyed couplings. All working ports follow SAE Code 61 flange standards to simplify hose selection; the inlet uses a 2.5 in Code 61 flange to minimize flow restriction, whereas the outlet is a 1 in Code 61 flange sized for pressure lines. A bottom-mounted drain port lets case oil return under gravity, and the .875-14 SAE O-ring connection on that port supports leak-free piping. A fluorocarbon shaft seal withstands hot hydraulic oil and extends service life in severe duty cycles. The pump also includes the Q250 valve plate, a feature that refines port timing to improve volumetric efficiency at higher speeds.
