Our grey cast iron pump housings are produced via resin coated sand one-piece casting with HT200/HT250 material, serving as core pressure-bearing shells for centrifugal pumps, pipeline pumps and circulating water pumps. Integrated double flange and internal flow guide ribs eliminate secondary welding, featuring stable pressure resistance, low noise and zero leakage risk. Full one-stop service includes casting, CNC machining, drilling tapping and anti-rust coating. Custom sizes, structures and paint colors are available for small samples and mass bulk orders. All goods pass water pressure leakage test before delivery.
