Features and Specifications

  • Can be used to deliver standard ASTM grout mixes, caustic remediation fluids and HRC® and HRC-X® high-viscosity materials.
  • Dual reciprocating pump-type pistons provide a near-constant flow of material.
  • The pump features a hydraulic cooling system for continuous operation at longer pumping intervals, like those required to deliver permanganates and other oxidants to remediate specific water treatment problems.
  • Operating the pump at higher pressures makes it possible to deliver grouting through a small-diameter tremie tube.
  • The unit's injection machine features a variable-speed control valve and emergency kill switch for precise operation.
  • A 9.5 gallon grout hopper is attached to the unit, making sure you have ample supply of pumping material on hand.
  • Piston pumps can be disassembled and cleaned in less than five minutes; other components are removable for easy cleaning.
  • Optional Viton seals are available for pumping harsh remediation chemicals.

  • A Self-Contained Pumping Powerhouse

    The Geoprobe GP300 grout pump is designed to act as a truly self-contained unit, requiring no external power source and capable of operation independent of a direct-push machine or carrier vehicle. Weighing 325 lbs when empty, the GP300 comes on a roller cart for easy movement around a job site. The cart's handles can be removed in order to facilitate transportation and storage.
