GPS-7A capacity adjustable mini concrete pump

GPS-7A capacity adjustable mini concrete pump 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. Gaodetec mini concrete pump equipped self-lubrication system for the wet shotcrete machine to automatic lubrication for main sealing parts, thus could lengthen wearing parts working life greatly.
Gaodetec capacity adjustable mini concrete pump 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 shotcrete machine outlet and add A percentage of the accelerator at nozzle, concrete slurry be sprayed to surface directly. 

1) Capacity adjustable mini concrete pump for conveying greening soil in ecological environment construction;
2) Mini concrete pump for conveying all kinds of engineering construction in the plain concrete, fiber concrete;
3) Mini concrete pump for conveying floor heating lightweight foamed cement, mortar, fine aggregate concrete;
4) Capacity adjustable mini concrete pump for conveying refractory and insulation materials;
5) Adjustable capacity mini concrete pump can be used for pressure grouting of foundation pile.

1. Trailer concrete pump is equipped floating wearing ring on S valve, could self-compensating wearing;
2. Main oil pump is variable displacement plunger pump, spraying volume could be adjusted freely;
3. Use S valve reversing, good sealing performance, longer working life; 
4. High outlet pressure, could meet the demands of concrete pumping for high building; 
5. Equipped self-lubrication system to automatic lubrication for main sealing parts, lengthen wearing parts working life;
6. PLC control, With wireless remote control, easy to operate;
7. Wet shotcrete machine with guide pulley, easy to move, location;
8. Accelerating adding quantity could be adjusted continuously.
9. Hydraulic system adopt air-cooler, easy operate, don’t need water; 
10. Air shotcrete machine with reverse function, reduce pipe plugged;
