Principle of Operation

Submersible centrifugal pumps work following the electric submersible pump operating principle. An encapsulated electric motor drives the centrifugal pump while the fluid’s kinetic energy increases. This energy is then partly converted into pressure, which lifts the fluid through the pump. The design uses a vertical shaft to rotate the impellers and pressurise fluid. The entire unit is submerged in the fluid, so it requires the use of mechanical seals to protect the electrical motor from failing.
