The Heidra 250 Hydraulic Submersible Pump is a self-contained, diesel powered 10" pump available for heavy duty municipal and industrial dewatering and solids handling pumping applications. The Heidra 250 offers flow rates up to 3500 gpm with up to 185' of total dynamic head and solids handling capability of 3-1/8" in diameter. The unit consists of a sturdy cast iron submersible pumpend and hydraulic power pack mounted on a rugged steel skid. A variable displacement hydraulic piston pump on the power pack delivers hydraulic fluid to a fixed displacement piston motor that drives the pumpend's shaft, bearings, and cast steel impeller. Simple engine throttle adjustments allow changes to pump flow and head performance.
