The pumps are available in pneumatic, hydraulic and electric models, and can be supplied in either 12 bar or 24 bar sizes. All varieties are capable of flow rates in excess of 70 lpm.
An upper 150 litre mixing tank mixes the cement and water in these grout pumps, before the mixture is fed into a holding hopper via a large 125mm butterfly valve.
Once in the holding hopper, operators can initiate the grout pump and grout whilst beginning the mixing cycle again.
This configuration offers significant advantages for operators. Mixing and pumping are constant, while the use of a helical rotor pump allows for the smooth pumping of cement. This significantly reduces the pulsations associated with piston pumps.
Housed on a heavy duty skid, these grout pumps have been designed to fit in IT baskets, or to be trailer mounted.
Hydraulic versions of the CM60 also feature a central control unit and flow control valves so operators can vary the speed of both the mixer and grout pump as required.
