concrete spraying pump for sale

The refractory concrete spraying pump uses a hydraulic or pneumatic system to deliver dry-mixed refractory materials (such as refractory castables and spray coatings) to the spray gun, where they are mixed with high-pressure water or air and sprayed onto the work surface. Its core principles include:
Dual-cylinder alternating feeding: Similar to a dual-cylinder piston engine, one cylinder draws material while the other pushes it, achieving continuous and uninterrupted spraying and ensuring stable pressure.
Hydraulic drive: A hydraulic pump provides power to drive the piston in reciprocating motion, adapting to the delivery of high-viscosity, high-density refractory materials.
S-tube distribution valve: Automatically compensates for wear gaps, providing excellent sealing performance and reducing the risk of grout leakage and pipe blockage.
Wear-resistant design: Key components (such as spectacle plates and cutting rings) are made of wear-resistant alloy materials, extending their service life.

High quality concrete spraying equipment is widely used in various construction projects, including but not limited to:
Tunnel and underground projects: used for tunnel lining, reinforcement and repair to ensure the stability and safety of underground structures.
Bridge and road projects: used for the construction of bridge piers, bridge deck paving and road reinforcement to improve the bearing capacity and durability of the structure.
Water conservancy projects: used for the reinforcement and repair of water conservancy facilities such as reservoirs and embankments to ensure the safe operation of water conservancy facilities.
Construction projects: used for reinforcement and waterproofing of basements, basement roofs, walls and other parts to improve the overall quality and safety of buildings.

According to the structure of the multifunction hose type concrete spraying pump for sale from china suppliers, the pump is divided into: vertical pump and horizontal pump; according to the sealed form, it is divided into: open pump, semi-sealed pump, and fully sealed pump.
