It is used in large-displacement spray mortar and pressure grouting machinery. It has high mortar conveying and spraying operation efficiency, long pumping distance, large pumping pressure, and easy to pump mortar containing large-particle aggregates.

It is suitable for all kinds of premixed mortars or freshly mixed mortars, and is used for building surface layer spraying, light steel building integrated wall filling grouting, concrete 3D printing, theme park landscape engineering decoration, heavy steel building fireproof mortar spraying, road and bridge and slope protection reinforcement grouting, large-area self-leveling ground construction, and is also used for facility construction and maintenance in wind power generation, steel and metallurgy and other industries.

Many advantages:
The machine is equipped with a unique screw pump (rotor, stator) to load and unload the guide rails immediately on site, and update and disassemble the screw pump (rotor, stator). There is no cumbersomeness at all and there is no need to bear the load.
Unique drive shaft design: The interrupted spiral sheet has the function of repeating secondary stirring of the slurry, ensuring that the mortar in the silo does not segregate, precipitate, and does not expose water, and improves the thixotropy of the mortar.
The nozzle is made of high-strength stainless steel pressure precision cast monomer molding, which is not only wear-resistant and corrosion-resistant, but also has a smooth inner cavity to reduce the resistance to slurry passing through, ensuring that there is no slurry and smooth discharge.
Special drive component sealing mechanism ensures that the drive variable speed motor does not penetrate slurry and the transmission gear is not damaged.
