Heidra 300

The Heidra 300 hydraulic submersible pump is a self-contained, hydraulic-powered 12" (300mm) submersible pump with a diesel-driven hydraulic power unit available for heavy duty municipal and industrial dewatering and solids handling pumping applications.

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.

  • Cast iron pumpend with cast chromium steel impeller designed for general pumping with solids handling up to 3.75" (95 mm) in diameter.
  • Capable of flow rates to 6,000 GPM (1,363.3 m3/h) and heads to 200' (61 m).
  • Unique double mechanical seal immersed in isolated oil bath for unlimited dry running capability.
  • Integral 200 gallon (757 l) 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.
  • Standard PrimeGuard Controller provides programmable operations including setting maintenance timers.
  • Integrated steel cage on pumpend protects pump while submersed, provides a lifting bale for easy transfer and provides an anchor spot for the hydraulic fittings.
  • “Quick Disconnect” hydraulic fittings simplify setup, installation and shutdown.
  • Standard JD6068H engine. Other models, including electric drive versions, available.
