PSV-SSRF-40HRM-66-110/115

The PSV-SSRF-40HRM-66-110/115 is part of the PSV Variable Vane Pumps series from Bosch Rexroth and supplies hydraulic power where adjustable flow is required. The solenoid two pressure control lets the circuit switch between two preset pressure stages to match changing load conditions. At 1750 rpm the pump outputs 30 gallons per minute, providing steady actuator movement. A maximum operating pressure of 2000 psi supports medium-pressure automation without supplemental boosting. Right-hand rotation aligns with most clockwise prime movers, and rear porting directs hoses away from the drive shaft for compact installations. The unit is flange mounted so that shaft alignment with the motor is held firmly during operation.

A 1-1/2 inch inlet flange brings oil from the reservoir, while a 1-1/4 inch outlet flange delivers pressurized flow to the system. Both ports use a four-bolt flange connection that maintains clamping force under pulsation and simplifies service. Viton seals withstand common hydraulic fluids and elevated temperatures to minimize leakage. A screw-type volume control adjusts the vane cartridge eccentricity, allowing technicians to fine-tune displacement without removing the pump. These port dimensions and adjustment features help the pump integrate into standardized manifolds and match flow precisely to dynamic load demands in automated equipment.
