Casting Pump

A pump is a mechanical device that moves a fluid (liquid or gas, slurry). Pump casting is the process of designing and casting pump parts from different metals or metal alloys. It can provide higher strength and corrosion resistance and handle liquid substances.

We are one of the pump casting manufacturers and experts in China. We can produce any pump castings or cast pump parts in our foundry. Most of them are exported to USA, Germany, Japan and India and Pakistan markets.

We Offer Cast Pump Parts

We supply cast pump body, pump casing, impeller casting, pump mounting bracket. As well as other pump castings for oil fields, oil extraction and refining, petrochemical industry, water treatment industry, solid waste treatment, concrete construction, etc.

We can use various metal materials according to customers' needs. Such as heat resistant stainless steel, ductile iron, gray cast iron or other alloy steel. Our QC team and spectrometer ensure accurate alloy composition.

Pump casting production process.

Pumps come in many shapes and sizes for different applications. From very large shapes to very small shapes. From handling gas functions to handling liquids. From high pressure requirements to low pressure requirements. From high capacity to low capacity. So pumps can be divided into different types. Such as water pumps, hydraulic pumps, vacuum pumps, trash pumps, sewage pumps, etc.

For different pump types, we can use different casting processes.

 The main processes in our factory are as follows:

Lost Wax Casting

When the pump casting is made by stainless steel investment casting. Lost wax casting will be preferred. The casting has a smooth surface and tight tolerance. Just like valve castings. The lost wax process will reduce machining work and result in a uniform net shape casting. This will save time and cost by reducing most post-treatment and machining work.

Aluminum Die Casting

The die casting process is suitable for thin wall thickness requirements and special aluminum alloy materials. For example, mounting brackets. Aluminum die castings can achieve high strength and perfect quality. When you have wall thickness requirements, aluminum die castings are the better choice.

Sand casting

If pump casting choose iron or cast iron as raw material. Sand casting will be a better solution. Because sand casting has the advantage of low cost and good inherent quality. However, compared with investment casting, more machining allowance will be obtained.

In general applications, cast iron pumps are pump castings. They are more often used for water transportation. Stainless steel pumps are used for transporting corrosive media.

We will use tempering heat treatment process. To improve the mechanical properties, hardness, wear resistance and strength.

Casting Pump Parts Manufacturer

Zen Young manufactures a wide range of cast pump parts, and other pump casting industries for solid waste handling, oil extraction and refining, concrete construction, petrochemicals, and water treatment. We use a variety of casting alloys such as heat resistant stainless steel, ductile iron, gray cast iron, etc. depending on your needs. Our spectrometers ensure accurate alloy composition, regardless of material.
