Heidra 300

Summary

Product identification

• Model: Godwin Heidra 300 hydraulic submersible pump
• Part Number: 95-1205-1000
• TLPN: HS300-01-001
• Description: A compact, self-contained pumping unit featuring a diesel-driven power pack and hydraulic pump end. It offers variable speed operation to meet diverse flow and head requirements.
• Key Features:
  • Ability to handle solids up to 95 mm in diameter.
  • Indefinite dry running capabilities due to a double mechanical seal in its own clean oil bath.
  • Cast steel impeller for rugged dewatering and solids handling.
  • Safe pump end with no risk of electric shock or explosion.
  • Standard impeller designed for general pumping, slurries, and sludges.
  • Open solid handling impellers with replaceable wearplates.
  • Bearings are independent from the hydraulic gear motor, preventing pump loads from affecting gear motor performance.
• Standard Power Pack: Godwin Power Pack GHPU90 (TLPN: GHPU90-DBO-001 or GHPU90-DBH-001).
• Alternative Power Pack Options: Highway trailer, Site trolley, Electric motor drive.
