The PVQ40-B2R-SE1S-10-CM7-10 is a piston pump in the PVQ Piston Pumps series manufactured by Vickers. It supplies controlled hydraulic flow for automation circuits where consistent displacement and moderate pressure are required. An approximate weight of 20.6 kg (45.4 lb) allows straightforward handling during installation. A displacement of 2.500 in³/rev defines the fluid volume delivered per shaft revolution and sets the baseline flow rate. The rated pressure of 210 bar (3000 psi) permits operation in medium-pressure systems, while the rated speed of 1800 r/min establishes the nominal drive speed for performance data. Maximum input power at rated speed is 27.6 kW (37 hp), indicating the horsepower demanded from the prime mover. Inlet pressure limits of 5 inHg vacuum to 2 bar (30 psig) guard against cavitation and aeration at the suction side. Case pressure is capped at 0.35 bar (5 psig) to protect shaft seals, and a case relief set 0.7 bar above inlet pressure vents excess housing pressure before damage occurs.


The pump uses a drain port threaded 7/8-14 UNF-2B to route internal leakage back to tank. An inlet port thread of 1.875-12 UN-2B accepts standard suction fittings, and the 1.500 in O.D. inlet tube size maintains low inlet velocity to minimize pressure drop. The suction port follows the SAE O-Ring Boss pattern so an O-ring seal prevents air entry at the low-pressure side. Discharge is handled through an outlet port thread of 1.3125-12 UN-2B, and the outlet port is also an SAE O-Ring Boss design to contain the full 210 bar pressure without external leakage. An outlet tube size of 1.000 in O.D. provides the correct cross-section for rated flow. A shaft key measuring 0.250 × 1.250 in locks the drive shaft to the prime mover coupling and transfers torque without slip.
