The PVH57QIC RSF 1S 11 C25 31 pump belongs to the PVH and PVE Open-Circuit Piston Pumps series and is manufactured by Vickers for closed-loop hydraulic automation. It employs a pressure compensator to regulate output and protect actuators from overloading. A displacement of 57.4 cm³ per revolution lets the pump move 105 L/min at its rated speed of 2400 rpm, supporting medium-flow machinery. System safety is maintained with a maximum pressure limit of 250 bar, while clockwise rotation aligns with right-hand prime movers. A 1.25-inch input shaft transmits torque directly, and the SAE C four-bolt mounting flange anchors the housing securely to standardized engine or motor pads.
The hydraulic interfaces further streamline installation: a 2-1/2-inch SAE Code 61 suction port lowers inlet velocity, and a 1-3/8-inch Code 61 pressure port handles full working pressure. Case drainage is managed through a bottom port that uses a 3/4-16 SAE O-ring thread to simplify hose routing. A single fluorocarbon shaft seal resists fluid swell and heat, extending service intervals. There is no auxiliary mount, so add-on pumps cannot be stacked, and no diagnostic ports are present, requiring external test points for system checks. These connection, sealing, and mounting details enable dependable operation in automated hydraulic circuits.
