Investment Casting for Pumps and Valves

In pump and valve parts, flow-path geometry, sealing surfaces and corrosion resistance determine performance.

Why Investment Casting for Pump and Valve Parts?

Internal channels and impeller vanes can be cast as one piece. A smooth surface helps the flow, and sealing surfaces are machined where needed.

Typical Parts

Valve bodies and discs, ball valve parts, pump impellers, volutes, throat bushings and connecting elements.

Material Selection

316 is used with chloride-bearing fluids and 304 in general water and mild environments. Bronze is considered for seawater and wear. For details, see our 304 vs 316 comparison.

Tolerances and Quality

We cast parts to customer drawings. We can produce parts from 1 g to 25 kg and meet VDG P690 D3, the most precise class of the standard. See our tolerances page for the values.

Design Points for Pumps and Valves Parts

• State the pressure, temperature and medium for the body or impeller.
• Keep internal channels smooth and accessible for shell removal.
• Mark sealing faces and threads for machining after casting.

Frequently Asked Questions

Which materials are used for Pumps and Valves parts?

316 and 304 stainless steels and bronze are the most common choices.

Can you cast valve bodies with internal channels?

Yes, if the geometry allows the shell to be removed. Send the 3D model for assessment.

What part sizes and tolerances can you cast?

We cast parts from 1 g to 25 kg and meet tolerances up to VDG P690 D3.

What do you need for a quotation?

A drawing or 3D model, the material and the annual quantity. Price and minimum order quantity depend on the part.
