Hydraulically Driven Submersible Pump
Conventional Suction Pumps are limited in their application by the efficiency of their priming systems and in practice such pumps are restricted to an effective suction lift of 8 to 9 metres, to such an extent that at 9 metres lift some 90% of the output flow is lost. For lifts greater than this an alternative has to be found Submersible Pumps eliminate the problem of suction lift completely, and only have to cope with the discharge head and friction loss in the discharge hose. Having eliminated the limitations of the suction lift good output is maintained to great depths.
