refractory concrete spraying pump

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.
