PSV-6915413-66-110/115

The PSV-6915413-66-110/115 pump belongs to the PSV Variable Vane Pumps series manufactured by Bosch Rexroth for automated hydraulic circuits. As a variable displacement vane unit, it modulates output flow in response to actuator demand, improving energy use compared with fixed-delivery designs. Pilot-operated control provides stable pressure regulation without external feedback devices. The right-hand clockwise rotation direction matches standard electric motor couplings, while a maximum drive speed of 1800 rpm permits direct connection to four-pole machines. A mounting interface conforming to the ISO 3019-1 flange standard simplifies interchange with other frame-size pumps, and the ability to mount in any position gives designers freedom when arranging manifolds or power packs. An integrated solenoid rated for 110/115 V allows on-board directional or unloading functions without separate voltage conversion hardware.

The pump housing tolerates case pressure up to 10 psig (0.69 bar), preventing seal extrusion when back-pressure returns to the case. Fluid temperature must not exceed 130 °F so the elastomers and vane surfaces maintain service life. A minimum viscosity of 100 SUS is required to sustain the hydrodynamic film that separates the vanes from the cam ring during start-up and high load cycles. Inlet conditions are defined by a maximum vacuum of 6 inHg and a minimum absolute pressure of 0.8 bar (11.6 psia); staying within these limits avoids cavitation and preserves volumetric efficiency. Together these operating boundaries guide reservoir design, suction line sizing, and oil selection so the PSV-6915413-66-110/115 can deliver consistent flow and pressure in machine tools, presses, and other automated installations.
