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
