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 output 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.


Use S valve reversing, good sealing performance, longer working life;

  Equipped floating wearing ring on S valve, could self-compensating wearing;

  High outlet pressure, could meet the demands of concrete pumping for high building;

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

  With reverse function, reduce pipe plugged;

  Main oil pump is variable displacement plunger pump, spraying volume could be adjusted freely;

  PLC control, With wireless remote control, easy to operate;

  With guide pulley,  easy to move, location;

  Accelerating adding quantity could be adjusted continuously;

   Equipped self-lubrication system to automatic lubrication for main sealing parts, lengthen wearing parts working life.
