Pump and Valve Castings
What are Pump and Valve Castings?
Pump and valve castings are crucial metal components used in a wide range of industries to control and move fluids (liquids and gases). These castings form the core of pumps, which transfer fluids, and valves, which regulate or stop their flow. For both simple household plumbing and complex industrial processes, efficient and reliable fluid handling relies heavily on pump and valve castings. These components must withstand various stresses, pressures, and environmental conditions depending on their specific application.
Processes for Pump and Valve Castings
We produce pump and valve castings of varying sizes and complexities using processes such as investment casting, sand casting, shell mold casting, and die casting. We are capable of applying the optimal casting process, taking into account the application, component design, and performance needs, to make sure that each client’s unique specifications such as dimensions, chemical composition, physical and mechanical properties are precisely met.
Our investment casting process is designed for pump and valve accessories requiring high precision, high reliability, and intricate structures, such as precision valve bodies, complex pump impellers and critical components like mechanical seals. With our advanced silica sol process, we achieve excellent surface finish and dimensional accuracy for castings up to 50 kg, with near-net-shape capabilities significantly reducing machining. We offer customized investment casting services, producing a wide variety of pump and valve castings with diverse sizes, performance characteristics, structures, and materials to meet specific customer requirements.
Beyond investment casting, our professional sand casting production line efficiently produces large pump and valve components, including substantial pump housings and valve bodies, weighing up to several tons, suitable for applications where surface smoothness is not critical.
Our shell mold casting process provides an efficient and repeatable solution for medium to high volumes of pump and valve components demanding consistent quality and dimensional accuracy, offering a budget-friendly alternative to investment casting for parts like valve bodies, pump impellers, and smaller housings.
For high-volume production of lightweight (especially aluminum alloy) and precisely dimensioned components, our die casting methods—including high-pressure, low-pressure, and gravity casting—are an efficient choice for valve bodies, low-pressure pump housings, and control boxes, providing good surface finish and dimensional accuracy. In our specialized aluminum casting workshop, our gravity casting process can handle pump and valve parts up to 25 kg and over 1 meter in dimension.
Materials for Pump and Valve Castings
The demanding operating conditions of many pump and valve applications require the right material. We offer expertise in casting materials specifically chosen for their ability to withstand stress, wear, corrosion, and other environmental factors. Our material area of expertise for cast valve and pump components includes various grades of steel (carbon steel, alloy steel, stainless steel), cast iron, aluminum, and other non-ferrous materials such as zinc, bronze, and brass. Speak to us today to let us know your required material specifications.
Stainless steel cast parts are known for exceptional corrosion resistance and strength in harsh environments, especially when cast as valve bodies and pump impellers; common grades that we routinely cast include 304, 316, 347, and 2205.
Carbon steel casting provides a budget-friendly balance of strength and durability, often chosen for valve bodies and pump housings. Various grades of alloy steels used for cast pump and valve parts deliver high strength, toughness, and wear resistance for critical load-bearing and friction-prone components.
Aluminum, unlike other materials, is a great option for lightweight, corrosion-resistant, and thermally conductive parts such as pump impellers and low-pressure valve bodies. Cast iron, including both gray iron and ductile iron offer decent strength for most pump components and valve bodies at a much lower cost than steel. Let our experts know your requirements, including size and weight, performance criteria as well as your bugdet, so we can provide you with a quote based on the optimal materials.
