Knowing when to use this pump is important to the performance of this machine. As with all Geoprobe® tools and equipment, it's important to remember Team Geoprobe is ready to answer any question you may have about tool/machine usage.
GP300 Injection Machine
The
GP300 Injection Machine is a stand alone hydraulically-driven dual piston
pump.
Originally designed to pump high viscosity materals such as HRC®,
the GP300 can deliver grouts or remediation fluids at a rate of 3.5 GPM
with pressures up to 1850 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 nitrided steel to resist corrosion from everyday use and harsh chemicals. The piston pumps can be totally dissassembled, 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.
GP300 Injection Machine Features:
- High Pressure enables grouting by small tremie tubes.
- Inject HRC® (Hydrogen Release Compound).
- Self-contained unit. No other power source required.
- Uses a reciprocating-type piston pump and Honda engine.
- Capable of providing operating pressures up to 1,800 psi at 3.6 gpm.
- Manual start, 9 Hp gas engine
- Speed control on Grout machine.
- Grout pump cycling possible in manual or automatic mode.
- 9.5 gallon (36 L) grout hopper.
- Machine weight is only 325 lbs. (147 kg).
- Easy to disassemble for cleanup.
