The Duba pump has no reciprocating movement in its mechanism; all moving parts either rotate or oscillate and have roller bearings. It can be used for very deep wells and can discharge against a positive head of up to 20 m, if required. The pump can be easily equipped with an electrical motor, diesel engine, or a mechanism for animal traction.
