A piston pump including a membrane separating a product side from a hydraulic side for a hydraulic fluid, a reciprocating piston operatively active on the hydraulic fluid, and a valve system to establish a selective fluid communication between the hydraulic side and a tank containing the hydraulic fluid. The valve system includes a first valve arrangement that, in a working condition of the piston pump, is configured to discharge the hydraulic fluid having a pressure over a first threshold from the hydraulic side towards the tank and to draw the hydraulic fluid from the tank to the hydraulic side when a pressure in the hydraulic side dropping below a second threshold, and a second valve arrangement that, in at least one non-working condition of the piston pump, is configured to discharge the hydraulic fluid having a pressure over a third threshold from the hydraulic side towards the tank.

Membrane-based piston pump and a homogenising apparatus comprising the membrane-based piston pump

A high-pressure homogenizer, comprising: a plurality of pumping pistons (), for feeding a liquid to be homogenized toward a manifold (), each piston being associated with a respective oil hydraulic cylinder; a homogenizing valve positioned downstream of said pumping pistons (); and an electronic system () for controlling and regulating said pumping pistons (), which controls the law of motion of each individual piston () independently. Said electronic regulation system () is connected to a transducer placed on the manifold () to regulate the delivery of oil to the individual cylinders () according to the pressure, sensed in the manifold (), of the liquid to be homogenized pumped by said pistons () in order to maintain a stable flow rate and pressure.
