General guidelines on water suppy
To Operate correctly, the diaphragm pump must draw liquids from a container at atmospheric pressure.
DO NOT SUPPLY THE PUMP WITH PRESSURISED LIQUIDS!
for continuous duty, the pump should not draw in water by gravity from containers with liquid level at heights of above 3metres.
For continuous duty, the pump should not draw in liquids by vacuum from containers with liquid level more than 3 metres below the
pump intake fitting and the circuit must conssit of hoses of length and diameter appropriate to the pump intake fitting free from restric
-
tions and elbows and with a filter of suitable capacity.
For occasional duty, such as filling water supply tanks, the pump can be operated at a vacuum drawing in liquids from reservoirs hav
-
ing the surface of the liquid to 5 metres below the pump intake fitting, for preiods of no more than 15 minutes.
Drawing in liquids from lower levels or for longer times causes cavitation in the pump circuit and reduces the lifetime of the
diaphragms, valves and mechnical parts.
