Centrifugal pump

for chemicalselectricself-priming

Self-priming horizontal centrifugal pumps are an intelligent alternative to vertical pumps and submersible pumps. Having an appropriately modified screw, they are able to generate vacuum in suction that allows priming of the pump even in the negative suction head situation. This allows installation at ground level, on the edge of a pool, with the possibility of easily accessing the pump for maintenance operations. Economic advantage deriving from a simpler and faster maintenance that does not require to lift and move the pumps as it happens for vertical and submerged ones.
