Mortar spraying works under harsh conditions. Sand grains inside materials continuously wear down stator and rotor during long-time high-speed operation. Low-quality spare parts wear out rapidly, resulting in material leakage and insufficient pressure. Frequent replacement brings extra downtime and higher overall construction cost.

We adhere to craftsmanship and strict raw material inspection. Our rotors are made of high-strength alloy steel, processed by CNC precision machining and surface hardening treatment for outstanding wear resistance and deformation resistance. Stators adopt tear-resistant special rubber compound, suitable for abrasive building materials with superior anti-aging performance.

Under the same quality standard, our stator & rotor kits feature longer service life, reducing replacement frequency and maintenance cost. Every set is tested for pressure and sealing before delivery, with strictly controlled dimensional tolerance to ensure tight fitting after installation and avoid pressure loss caused by excessive clearance.

High-durability stator and rotor are critical to lower total construction cost. We focus on screw pump spare parts for spraying machines and supply cost-effective replacement parts with consistent quality for global contractors.
