Baoding Guokun manufactures a diverse range of pump castings, including:

pump casings, pump bodies, cast pump bodies, pump mounting brackets, cast pump impellers, volutes, pump casing covers, rear liners, pump volutes, pump bearing brackets, pump vanes, and all other customised pump casting components.

These are suitable for centrifugal pumps, vertical centrifugal pumps, fire hydrant pumps, gear pumps, vane pumps, piston pumps, vacuum pumps, and water pumps. Depending on pump type and requirements, Baoding Guokun employs heat-resistant stainless steel, ductile iron, grey cast iron, aluminium alloys, and other metallic materials for casting and machining various pump replacement components.

What is a pump casing?

The pump casing is a metal-cast housing, volute, or pump shell designed to contain the pump body and protect internal components. It permits fluid passage while maintaining pressure and prevents leakage by sealing the pump's interior from atmospheric exposure.

Centrifugal pumps primarily feature two casing types: volute and diffuser. The diffuser configuration represents the most common casing classification, wherein the diffuser comprises a series of guide vanes encircling the impeller to receive the discharged fluid.

Pump body casting machining processes:

Precision Cast Steel Pump Components: The silica sol precision casting process is a highly efficient and accurate casting technique. It delivers high-precision, near-net-shape castings with smooth surfaces for stainless steel pump components in grades such as UNS S31600, 316, 304, 316L, CF8, and CF8M, thereby reducing machining operations.
