Diesel shotcrete spray pump machine
Shotcrete machines are widely used by many contractors. The diesel shotcrete spray pump machine has excellent quality and reliable performance; good sealing performance and less dust; reasonable design and easy movement; the four-point clamping device is convenient for adjusting the pressure between the sealing plate and the rotor disc, without air leakage and dust leakage, and prolongs the service life of wearing parts. The use of fine flow conveying and vortex conveying makes the spray flow uniform, continuous, and stable, improving the quality of concrete spraying.
The diesel shotcrete spray pump machine is equipped with a rotor feeding system, which can work continuously to ensure long service life and low maintenance costs. We provide a variety of hose and nozzle options to meet the needs of shotcrete applications. It is widely used in concrete spraying operations in tunnels, culverts, subways, hydropower projects, underground projects, and high-gas tunnels in coal mines.
