  • GP300


    GP300The GP300 Injection Machine is a stand alone hydraulically-driven dual piston pump. Originally designed to pump high viscosity materials such as HRC®, the GP300 can deliver grouts or remediation fluids at a rate of 3.5 GPM with pressures up to 1300 PSI. The power plant behind this pump is a manual start 9 HP Honda gasoline engine. It features a hydraulic cooler for longer pumping intervals, such as when pumping permanganates, and a battery for a reliable electrical system.

    Dual pistons on this pump provide a nearly constant flow of material. The pump components are constructed of stainless steel and nitride steel to resist corrosion from everyday use and harsh chemicals. The piston pumps can be totally disassembled, cleaned, and reassembled in less than 5 minutes.

    Although the GP300 was originally designed to pump HRC®, it is certainly not limited to pumping the most abrasive grouts and the most caustic remediation fluids.
