SELF PRIMING PUMPS
FOR
CLEAR LIQUIDS
A normal Centrifugal pump cannot be used for volatile solvents for negative suctions, because foot-valve elastomers give problems and the pump also faces cavitations.
Self Priming pump developed by POLYQUIP, removes the above problems, but, can be used for clear liquids only. The pump is provided compulsorily with Mechanical seal, it does not come with Gland packing arrangements. It can take a negative suction pipe length of 3to4 meters, without foot valve. Initially, the casing only is to be filled with liquid to avoid damage to the seal due to dry running.
Self Priming pump is provided with star vane type impeller and can be used for low capacities only, upto 50 L.P.M. and heads upto 40 meters. An ideal pump for underground storage tanks, barrel emptying and other applications. The pump is available in S.S. material of construction, only.
