DMAR series grout pump is widely used in highway, railway tunnels, subway, underground caverns and other hydropower projects anchoring perfusion pulp can be used for dams, slope, soft rock reinforcement when the soil grouting, anchoring grout is solid Results grout, backfill grouting and curtain grouting construction site ideal modern construction equipment. Features a compact simple structure, high reliability, electrical components imported components. 2, simple operation and maintenance. 3, light weight, wheel design, easy to move. 4, liquid grout cement ratio range, especially suitable for high density thick slurry design requirements. 5, sand lime slurry perfusion ratio, wide sand particle size range. 6, continuous grouting piston pump to avoid excessive transient pressure fluctuations. 7, passive boost. When the slurry filled, the pressure gradually increased, easy to control and maintain the grouting pressure. 8, after grouting pressure reaches the design pressure, pressure relief can be reversed. 9, with the compressor and injectors, can be interior and exterior primer and spray protective overcoat layer. 10, the machine is a single pump, you can not add accelerator class admixtures.

Note: different water-cement ratio, the amount of pulp vary Cautions 1. Before using the machine, check all parts of the machine assembly is solid, Tighten the screws ; 2, before grouting, the first water test machine and check the machine forward and reverse. 3, machine use is prohibited during operation disassemble, adjust the machine the parts. 4. After grouting, grout must be cleaned and grouting pump hose, each switch in the stop-off location, promptly cut off the power supply; 5, no time can hand into the hopper or hard objects placed within the operating screw conveyors ; 6, each machine has been tested at the factory is good, and the stator, the rotor tightness of fit, Do not adjust the stator fastening screws.
