PSV-PSAF-15ERM-66

The PSV-PSAF-15ERM-66 variable vane pump belongs to the PSV Variable Vane Pumps series from Bosch Rexroth and supplies hydraulic power for automated machinery where adjustable flow is needed. A displacement of 25 cm³ per revolution defines the fluid volume moved each shaft turn, making output predictable in proportional control loops. When the shaft runs at 1800 rpm against 100 psi, the pump delivers 43.5 L/min, providing steady medium-capacity flow for actuation circuits. Drive speed can be set between 750 rpm and the maximum 1800 rpm, so users can tailor flow to real-time load demands without swapping hardware. Right-hand rotation aligns with common motor couplings, while the ISO 3019/1 mounting interface lets the housing bolt directly onto standard power units. The unit tolerates installation in any position, simplifying reservoir layout.

The pump sustains system pressure up to 138 bar (2000 psi), enabling operation in moderate-pressure servo or proportional valve networks. Inlet conditions are bounded by an absolute minimum of 0.8 bar to prevent cavitation and an absolute maximum of 1.7 bar to avoid seal loading, supporting stable suction across varying tank heights. SAE straight-thread ports provide leak-resistant connections that match widely used hydraulic fittings, reducing assembly time. At 21 kg (46 lb), the housing requires a rigid mounting plate but remains light enough for single-person handling during service calls. These characteristics, combined with the variable vane design, allow the PSV-PSAF-15ERM-66 to regulate flow accurately while meeting space, pressure, and plumbing requirements in industrial automation systems.
