LPS-7A wet gunite machine use hydraulic pumping S valve structure, two oil cylinders reciprocating motion alternately to pump concrete from conveying pipe to nozzle, Add compress air to wet gunite machine outlet and add A percentage of the accelerator at nozzle, concrete slurry be sprayed to surface directly.

LPS-7A wet gunning machineoutput could be adjusted continuously: main oil pump is variable displacement plunger pump, spraying volume could be adjusted freely. Accelerating adding quantity could be adjusted continuously: according to concrete spraying volume adjust step-less.  Leadcrete equipped self-lubrication system for the wet gunite machine to automatic lubrication for main sealing parts, thus could lengthen wearing parts working life greatly.


LPS-7A wet gunite machine used for wet concrete spraying in mine, tunnel, culvert, metro, hydropower engineering, underground construction, slope protection etc. or for filling, grouting pumping concrete mortar etc.

1. Pneumatic wet gunite machine uses S valve reversing, good sealing performance, longer working life;
2. Wet Gunite Machine is equipped floating wearing ring on S valve, could self-compensating wearing;
3. High outlet pressure, could meet the demands of concrete pumping for high building;

4. Hydraulic system adopt air-cooler, easy operate, don’t need water;

5. Pneumatic wet gunite machine with reverse function, reduce pipe plugged;
6. Wet gunning machine main oil pump is variable displacement plunger pump, spraying volume could be adjusted freely;
7. PLC control, With wireless remote control, easy to operate;

8. Air wet gunite machine is with guide pulley,  easy to move, location;
9. Accelerating adding quantity could be adjusted continuously;
10. This wet concrete spaying machine Equipped self-lubrication system to automatic lubrication for main sealing parts, lengthen wearing parts working life.
