The 50HSD is a high efficiency hydraulic submersible pump powered by a diesel-driven hydraulic power pack capable of delivering flows of up to 48m3/hr and heads of up to 26m.

Pioneer hydraulic pumps come as standard in fully bunded, sound-attenuated canopies complete with 120% containment and lockable doors, allowing the pumps to be used in urban bypass applications at less than 65dB(A) at 7 metres.
