Pump Components FAQ
What pump components can you manufacture?
We manufacture custom pump components including pump housings and volutes, impellers and diffusers, shafts and sleeves, mechanical seal components, bearing housings, valve bodies and seats, and custom pump hardware. Our CNC machining capabilities cover single-off prototypes through production runs.
What materials are best for corrosive pump applications?
For corrosive applications, stainless steel 316 and 316L offer excellent general corrosion resistance. Duplex 2205 and super duplex stainless provide superior resistance to chloride stress corrosion cracking. Titanium and Inconel are used for extreme corrosive or high-temperature environments. Aluminium bronze is ideal for seawater applications.
What tolerances can you hold on impeller balancing?
CNC machining holds tolerances to ±0.05mm on general features. High-precision work achieves ±0.01mm. For impeller balancing, we work to ISO 1940 balance standards (G2.5 for centrifugal pumps, G1.0 for high-speed turbomachinery). Dynamic balancing is available for rotating components.
What is the typical lead time for pump components?
Simple pump components: 2–3 weeks. Medium complexity: 3–4 weeks. Complex precision assemblies: 4–6 weeks. We provide a detailed quote with lead time based on your specific geometry, material, and quantity.
Can you manufacture replacement parts for obsolete pumps?
Yes. We reverse-engineer obsolete pump components from samples or detailed drawings. We manufacture replacement pump housings, impellers, and wear parts in original or improved materials.
Do you offer dynamic balancing for pump impellers?
Yes. Dynamic balancing is available for pump impellers and rotating components. We balance to ISO 1940 standards and provide balance certificates upon request. This is essential for high-speed centrifugal pumps.
