The PVB6-RS-40 CM 12 pump is produced by Vickers within the PVB Piston Pumps series for hydraulic automation where stable flow and pressure control are required. It is an axial piston unit that employs a pressure compensator (CM) to maintain outlet pressure without manual intervention. The geometric displacement is 13.81 cm³ per revolution, so each rotation delivers a fixed fluid volume. When driven at 1800 r/min, the pump supplies a rated flow of 22.7 L/min. The mechanical design supports a maximum shaft speed of 1800 r/min and sustains up to 140 bar outlet pressure during continuous duty. Viewed from the shaft end, the rotation is clockwise, matching common motor drive arrangements.
Flow is generated on one side of center, which simplifies circuit balancing in single-direction systems. The inlet port tolerates pressures up to 1.0 bar, allowing flooded suction without risk of cavitation. Mineral oil temperature may rise to 80 °C while the surrounding environment can reach 70 °C before derating is required. Operation remains possible down to −20 °C, extending service into cold start conditions. Acoustic emission is measured at 57 dB(A) with the pump running at 1000 r/min and 140 bar, supporting noise-controlled installations. These environmental and acoustic limits complement the hydraulic ratings stated earlier and define the boundaries for reliable machine performance.
