Pump

The pump is radial with rotary pistons, assembled in a single block with an electric motor and a special reservoir - accumulator for the hydraulic fluid.

On the pump casing (1) there is the stator (4) fitted with an eccentric chamber inside which the rotor (3) turns, changing the volume occupied by the working fluid: from the inlet hole (E) the pistons (2) - pushed outwards by the centrifugal force - make the fluid flow inside the pump; from the opposite side the pistons (2) push the fluid inwards which at high pressure goes out of the delivery hole (A).
