Lutz double diaphragm pumps · Functions In detail: the overpressure created in the chamber (A) closes the suction valve and opens the pressure valve so that the liquid is pumped into the pressure line. At the same moment, the same procedure is performed in reverse in chamber (B) in the negative pressure area. The pressure valve closes and the suction valve opens, enabling the liquid to flow in on the suction side. The Lutz double diaphragm pumps are oscillating The flow rate is determined by the number of cycles displacement pumps and operate volumetrically. per unit of time multiplied by the...
