Operating principle

Operating the equipment consists of elevating the pressure through a mix of a gear pump plus a piston pump up to an initial low pressure. They are moved by a one phase electric motor, isolation class B (155˚C) and IP54, valid for continuous or intermittent use. Above this initial pressure, the gear pump flow is redirected into the tank so that only the piston pump continues to raise the pressure until reaching the set value (through a manual valve). This dual pump system allows the motor to reduce the current consumption without affecting the performance.
