The Duba pump is a wheel-operated lift pump used for depths of up to 100 metres. The minimum borehole diameter required is 100mm. This pump meets VLOM requirements.
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.
