Continental Hydraulics PVER pumps are variable displacement vane pumps. They have a pressure regulator adjustable load spring that keeps the pump group cam ring in eccentric position.
When the outlet pressure equals the pressure corresponding to the spring setting, the cam ring is moved so to reduce the displacement, adjusting the flow rate to the values required by the system. In zero flow demand conditions, the pump delivers oil only to compensate for any system leakage,keeping the circuit pressure constant.
PVER pumps have pressure-balanced thrust plates that improve and maintain the volumetric efficiency throughout the pressure range.
The series is available in 4 nominal displacements: PVER-3B (6.6 cc/rev) | PVER-5B (11.1 cc/rev) | PVER-7B (16.6 cc/rev) | PVER-10B (22.2 cc/rev)
Across the range, operating pressure is 70 bar (1000 psi), flow at 1800 rpm ranges from 12 litres/minute to 40 litres/minute. Operating speeds are from 800 rpm, minimum, to 1800 rpm, maximum.
