Heidra 250
The Heidra 250 Hydraulic Submersible Pump is a self-contained, diesel powered 10" (250mm) 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.
- Rugged construction of cast iron pumpend with cast chromium steel impeller.
- Flow rates to 3500 gpm and heads to 185'.
- Unique double mechanical seal immersed in isolated oil bath for unlimited dry running capability.
- Integral 175 gallon fuel tank capacity provides over 24 hours of continuous operation.
- Safety shutdown system incorporated into engine controls prevents equipment damage from engine fault or failure.
- Impeller designed for general pumping with solids up to 3-1/8" in diameter.
- “Quick-Disconnect” hydraulic fittings simplify setup, installation, and shutdown.
- Standard John Deere 6068T engine — other models including electric drive versions available.
