WindTrans Systems Ltd.

Quite simply, Zelda HVLS is a high volume low speed pump that will change how the world moves fluids: quickly, efficiently and easily. WindTrans Systems has produced the first high-flow rate pump that operates efficiently at low rotational speeds in either pump or turbine mode. The low working speed allows operation by hand, kinetic power or by motor making it possible for remote use or during times of power failure. At 220rpm Zelda displaces 330 US Gallons per minute or 75.9 cubic meters per hour.
