The piston is mechanically connected to the diaphragm. The diaphragm is mechanically operated by the piston and at the same time its outer edge ensures a watertight seal around the pumping chamber. In a “semi-hydraulic diaphragm pump”, the diaphragm is rigidly secured to the piston by means of a pin in the centre screwed to the piston itself, while in a “hydraulic diaphragm pump” the centre of the diaphragm is fixed to a floating element on the piston. The suction and delivery valves, fitted at the pumping chamber intake and delivery ports, are operated by the alternating negative and positive pressure inside the circuit.

Suction: During the suction stroke (piston retracting), the difference between the suction pressure and the pressure inside the head opens the suction valve and closes the delivery valve. The process liquid is drawn into the head by the suction line.

Compression: During the compression stroke (piston extending), the suction valve closes and the delivery valve opens due to the pressure generated inside the head by the piston. The process liquid is pumped out of the head and into the delivery line.
