Unlike the conventional borehole pump which uses centrifugal force as the energy to move the water, the Subrotor uses the progressing cavity rotor/stator principle to draw water up.
Being a helical rotor pump, the Subrotor will produce a steady flow and is not affected by changes in differential pressure either in the bore or on the surface.
Features and Benefits of the Subrotor Helical Rotor Pump:
The rotor sweeps the full surface of the rubber stator so it is impossible for growth or iron oxide deposits to develop on the surface
The progressing cavity pump principle does not just spin water along, it pushes encapsulated water with positive force, so that ample volume is maintained at high heads
Subrotor pumps waste the least possible energy on internal friction, especially compared to multi-stage and jet pumps
Electric single or three phase option
Hard chrome plated rotor which is 4 times harder than the stainless you find in centrifugal pumps
With only one moving part, the rotor, the pump is easy to maintain with just a wrench
