PSV-SNAF-25ERMH-66-110/115-66

The PSV-SNAF-25ERMH-66-110/115-66 hydraulic pump is part of the PSV Variable Vane Pumps series from Bosch Rexroth and is designed to supply adjustable flow to automated hydraulic machinery. It is a variable volume vane design that delivers 20.2 gallons per minute when driven at 1800 rpm, enabling moderate system throughput without excessive drive power. The right-hand rotation orientation matches standard clockwise prime movers, and the internal rotor carries 11 vanes for smooth displacement with low pulsation. Hydraulic connections are arranged on flange side ports that use SAE threads; the inlet accepts an SAE 24 port with a 1-7/8-12 thread, while the outlet is sized for an SAE 16 port with a 15/16-12 thread. These port dimensions support straightforward integration with common hose and tube assemblies used in industrial power units.

Pressure and control functions are handled by a solenoid two-pressure circuit that shifts the pump between a low side rated at 1000 psi and a high side rated at 2000 psi, allowing automatic adaptation to changing load requirements. The absence of volume control means displacement remains fixed within each pressure stage, simplifying tuning for machines that rely on predictable flow. A Viton seal set resists mineral oil and elevated temperatures, extending service intervals in continuous duty environments. The pump mounts on the same flange that carries the side ports, minimizing envelope size inside compact power packs. By combining the specified pressure schedule with electric actuation, the unit delivers repeatable performance in press clamping, fixture positioning, and other automated hydraulic tasks that demand two discrete pressure levels without manual intervention.
