Hand Pump - Hand Crank Manual Operated Pump

Hand Pumping - Zelda HVLS can be hand driven by one or two hand cranks at the same time producing over 1.5 gallons per revolution. When hand cranking our test have shown that one can generate over 130 US gallons of volume per minute. These platforms are light weight and easy to maneuver making Zelda an ideal system for pumping high volumes of fluid at low rpm. Shipyards and barge bilge cleanout, Oil Spill recovery, emergency services for fire, flood and spills, irrigation and many other applications are addressed using the Zelda HVLS and her multi-platform drive capabilities
