Pneumatic Grouting pump is designed for pressure and filling grouting of cement and bentonite slurries. It is primarily used for injecting (grouting) bar anchors and the drill holes in order to reinforce the loose rock mass. The maximum grain size cannot exceed 0.2 mm.
Grouting pump operation and maintenance is simple, safe and reliable. This pump is used in mines operating under difficult conditions because it is reliable and explosion-proof.
Basic Pneumatic Grouting pump include: An air inlet, the pneumatic cylinder, mounting base frame and stand, pressure gauge, pumping cylinder, outlet with quick release coupling and wheels.
How it works
Pneumatic pressure in the air cylinder exerts a high pressure on the grout mixture which leads to ejection of grout with a high pressure and velocity. The valves of the air cylinder in the pump function automatically to actuate the cylinder. The pneumatic cylinder then moves the plunger up and down to complete the pumping cycle.
Pneumatic grout pump can be driven even without Electrical power supply in remote areas by using engine driven compressor.
Applications
The pump is majorly used in construction and mining industry for injecting material into wide and medium size gap in beams, columns ,basement walls and flooring, lift shaft concrete wall fill-up etc. In mining industry it is used to fill up cement solution where there is a gap exists between structure and rock and for soil stabilization.
Detachable design tends to easy maintenance and transportation. Challenging works like Grouting in Bridges.

This pump is widely used in tunnels, coal mine, bridges and dams, building foundation, and other underground projects, and inflammable, explosive sites and other bad environment.
It has application in chemical industry also to pump out chemical slurries.
The pump is electricity free so, can be used at any site condition whether it is rural or urban.
Mining Pneumatic Grouting pump has a larger discharge slurry adjustment range. Generally the final amount of the grouting volume is 8 or10 times of the amount in the beginning. And the final grouting amount proves that filling is compacted.
Simply put; Pneumatic high-pressure grouting pump is specially designed for high-pressure grouting. And it adopts full hydraulic drive, it’s pressure and flow can be adjusted according to the requirements of grouting,(The flow of grouting pump is 0-100L/min, pressure of discharge is 0-10MPa).besides, This Pneumatic high-pressure grouting pump can be used for grouting single or double fluid.
High-pressure grouting pump is mainly used for highways, railways, water and electricity, construction, mining etc. ground/underground construction.
Benefits
Mining Pneumatic Grouting pump has the advantages of low energy consumption, small vibration, low noise, small size, high efficiency, reliable performance, pressure and flow control, long life and so on. Common mine grouting pump has pneumatic injection pump, dual fluid injection pump, extrusion injection pump and piston injection pump.
Pneumatic grout pump is also Light weight and with a wheelie design it can be carried easily. It is designed for easy operation and low maintenance. Last but not least its spare parts are easily available.
