The PVE35R 1 22 C25V 21 pump belongs to the Piston Pumps series from Vickers and supplies controlled hydraulic energy for automated industrial equipment. A rear-mounted pressure-compensated, load-sensing control modifies swashplate angle to match system demand, allowing efficient operation under variable loads. Displacement is fixed at 4.5 cubic inches per revolution, and at 1800 rpm the unit outputs 35 gallons per minute for cylinders, motors, or logic manifolds. Right-hand (clockwise) shaft rotation aligns with standard electric motor drives, while a straight keyed input shaft transfers torque without splines. A single shaft seal contains the working fluid and minimizes maintenance requirements.
Side-oriented SAE ports with four-bolt flanges simplify rigid pipe runs and support high flow without excessive pressure drop. The integral pressure limiter is factory set to 250 bar, equal to 3625 psi, so downstream valves and actuators remain within safe stress levels during load spikes. Fluid entering the pump must achieve ISO 19/15 cleanliness or better; this filtration threshold preserves bearing surfaces and extends service intervals. Together these connection, protection, and contamination control features let the pump maintain precise pressure and flow in machine tools, molding presses, and other automated circuits that depend on reliable hydraulic motion.
