Double diaphragm pump - operating principle
The double diaphragm pump is driven with compressed air.
Two diaphragms (A) are mechanically connected to each other by means of a shaft (B).
Each diaphragm generates two chambers: pumping chamber (P) and motor chamber (M).
A pneumatic distributor alternately supplies compressed air into one of the driving
chambers (M), thus producing the diaphragm's movement and consequently causing one
of the pumping chambers (P) to empty (as a result of volume decrease), while at the same
time the other chamber (P) sucks the fl uid in (as a result of volume increase). A series of four
non-return valves (C) prevents the liquid from fl owing back, thus producing the suction
and delivery phases in each pumping chamber, and generating the pumping eff ect.
The ZIP models are equipped with an internal safety valve that opens when the maximum
allowed value of air pressure supply is exceeded.
Overpressure!
Risk of injury from bursting components.
