Screw cement grouting machine 
 DMAR--2/3/5/7 
 Widely used in road the DMAR series grout pump, anchor perfusion pulp works of the railway tunnel, the city subway, hydroelectric underground caverns can be used for dams, slope, soft rock reinforcement, soil grouting, anchor grouting, consolidation grouting, backfill grouting and curtain grouting construction site of the ideal modern construction equipment. Cement grout pumps, grout pump, concrete pumps, mortar pumps, dams, cement grouting, cement grouting pump, screw pump screw screw pump, concrete pump, screw mortar pump, mud pump, screw mud pump 

 Feature 
 1, compact and simple structure, high reliability, electrical components, using imported components. 
 2, operation and maintenance simple. 
 3, light weight, wheel design, easy to move. 
 4, grout cement ratio range is particularly suitable for the design requirements of the high concentration of thick syrup. 
 5, perfusion can be serous Fui Sha wide range of sand particle size. 
 6, continuous grouting to avoid the piston pump is too large instantaneous fluctuating pressure. 
 7, the passive boost. When the slurry is filled, the pressure is gradually increased, and easy to control and maintain the grouting pressure. 
 Grouting pressure to meet the design pressure can be reversed relief. 
 9, with the air compressor and spray the interior and exterior of the underlying and overlay layer spray care. 
 10, the unit is a single pump, can not add admixtures of the accelerating agent class.
