GRD Series Screw Grout Pump

Description

This pump features with newly designed structure which avoids the shortcoming of usual pumps when grouting thick mortar. It is more safe and efficient to use. This machine consists of motor, gearbox, slurry conveying part, supercharge worm, supercharge stator, pressure capsule, hopper, electric control, and sprayer when it is applied for spraying.


Feature

1. Simple structure, more stable with imported parts

2. Easy-maintaining

3. Light-weight, wheel-type, easy-transporting

4. Wide range for cement and water, suitable for thick mortar

5. Wide range for cement and sand ratio, wide range for aggregate

6. Continuous grouting which avoids large instantaneous pressure fluctuation of piston pump

7.  When grouting fully, pressure increases gradually, make it is easy to control and maintain pressure.

8. Could relief pressure reversely when the grouting pressure reaches the designed.

9. Could spray the lower inner and external wall and skimming coat when working together with air compressor and sprayer.

Application

This pump can be widely used in anchor grouting and consolidation grouting in road, railway tunnel, metro and hydropower station, pressure grouting in dam, side slope consolidate soft rock, and spraying protection of lower inner and external wall and skimming coat in city building constructions.
