also oiled compressed air.
2.1
Functional principle
Compressed air is applied to the pressure chamber within the housing via an external pneumatic
valve. This displaces a pneumatic diaphragm and the resulting axial movement is transferred to
the metering diaphragm via a tappet. This diaphragm impulsively expels the metering medium
from the liquid end through the pressure valve and the balls on the suction side close.
The pneumatic valve having switched, the pressure chamber is relieved and the tappet together
with the metering diaphragm is restored to its original position through the spring. The medium is
sucked into the liquid end through the suction valve and the balls on the pressure side are closed.
2.2
Pump drive
The Pneumados pump drive is operated solely pneumatically with a continuous max. stroke
frequency of 180 strokes/min.
The metering stroke is set to 10 - 100% using a stroke length adjustment (10).
The stroke length is max. 1.25mm.
NOTE
Settings should only be made with the pump in operation – when the adjustment pin of the
metering stroke is momentarily relieved!
2.3
Delivery unit
The Pneumados metering pump is equipped with genuine ProMinent
type series 1000 - 0220.
The liquid end with double-ball valves in the suction and pressure valves is available in the
following material types:
PV = PVDF
SS = stainless steel (material number 1.4571).
