Thanks to the reliability and versatility of our PR series radial piston pumps, we produce high-low pressure multiple pumps coupled with gear pumps or vane pumps.
Radial piston pumps + gear pumps Group 1, 2 and 3 are available in the price list. This type of coupling is ideal for presses, press filters and in all systems that require a quick approach of the actuator and a high pressure work considerably reducing the size of the engine used.
Our double pumps consist of a primary gear pump (BP) connected by coupling to the motor and a radial piston pump (AP) mounted on a tandem. In the “Pressure Control Valves” section, high-low pressure relief valves are available.
Special couplings are made on request and according to customer specifications.
Natural combination of one or more Low Pressure pumps and a High Pressure stage, is the ideal element to move one or more differentiated loads. This series is a 2-stage pump with constant displacements: a low-pressure pump fanged on the axis of a radial piston pump.
The Low Pressure stage consists of a self-compensated gear pump of the Vivoil brand of the Constructive Group 1 or 2; while the High Pressure stage consists of a radial piston pump of the PR series.
