Propeller pumps- type PR are suitable for transport of thin fluids applied in food and petrol-chemical industry as well as in mater-supplying systems and systems for cleaning out waste maters with insufficiently strong jots. Their main characteristic is relatively high capacity of raising of the fluid at small heights. Q-H diagram is characterized by almost horizontal curve within small heights of raising. Possible performances concerning the applied materials are steel, stainless steel or PVC plastic.
As for as constructive performance is concerned, propeller pumps are made of an appropriate mechanical seal with pressure from 0,2 to 0,7 (bars). The capacities are in three categories of pumps, and they are with capacity from 2 to 5 (m3/hour), from 7 to 10 (m3/hour) and to 20 (m3/h).
