LPS-7A small 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 portable concrete pump outlet and add A percentage of the accelerator at nozzle, concrete slurry be sprayed to surface directly.

LPS-7A small portable concrete pump output could be adjusted continuously: The main oil pump is a variable displacement piston pump, and the fuel injection amount can be adjusted freely. Accelerated addition can be continuously adjusted: stepless adjustment according to the amount of concrete sprayed. Leadcrete small mini concrete pump equipped self-lubrication system for the mini concrete pump to automatic lubrication for main sealing parts, thus could lengthen wearing parts working life greatly.  

► Application:

1) Small concrete pump that transports green soil in ecological environment construction;

2) Small mini concrete pump for conveying various engineering constructions in ordinary concrete and fiber concrete;

3) Mini concrete pump for conveying lightweight foamed cement, mortar and fine aggregate concrete for floor heating;

4) Small concrete pump with adjustable capacity for conveying refractory materials and insulating materials;

5) Adjustable capacity concrete pump can be used for pressure grouting of foundation piles.

► Features:

1. Accelerating adding quantity could be adjusted continuously;

2. With guide pulley, easy to move, location;

3. With reverse function, reduce pipe plugged;

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

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

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

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

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

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