Manufacturing Investment Castings for Submersible Pumps — Our Process
Our lost-wax casting process is engineered to deliver near-net-shape components with consistent quality across production runs.
- Wax pattern: Positive wax impressions made from precise molds to ensure repeatable accuracy across batches.
- Shell formation: Optimal ceramic shells made from up to eight coatings of ceramic slurry and stucco for favorable thickness.
- Component formation: Gradual introduction of molten alloys into the shell cavity and gradual cooling to form the required parts.
- Heat treatment: Placing knocked-out and fettled components in pre-heated furnaces to improve physical and metallurgical properties.
- CNC machining: Machining fettled parts to achieve the required surface finish and dimensional tolerances.
- Final inspection: Physical tests, non-destructive tests, and visual inspections to ensure product integrity and provide performance assurance.

Submersible Pump Applications Across Industries
Submersible pumps are preferred in the following industries for submerged applications because they avoid suction-side cavitation issues and don’t require priming.
Oil & Gas
Electrical submersible pumps (multi-stage) raise crudes to the surface of the oil wells when reservoir pressure is too low for natural flow.
Industrial processing
Handling process water, cooling fluids, and effluent treatment flows across manufacturing sites.
Construction & Mining
Dewatering excavation tunnels, mines, and foundations, including water with sand particles.
Marine & Offshore
Bilge pumping, seawater handling, and drainage applications on ships and offshore rigs.
Wastewater & Sewage
Moving sewage from wet wells to lift stations, transferring return activated and waste activated sludge, and discharging the treated effluent.

Frequently Asked Questions
Your castings for submersible pumps are for which submersible pump types?
We primarily manufacture investment castings for multi-stage submersible pumps, which are among the most requested configurations. However, we also produce investment castings for single-stage and positive displacement submersible pumps.
Do you assemble the investment castings for submersible pumps?
No, we do not assemble the investment castings for submersible pumps. We produce and supply them as-cast, roughly machined, or finely machined, as per requirement.
Can you customize your investment castings for submersible pumps?
Yes, we can customize investment-cast submersible pump components based on your proprietary design, specified alloy requirements, dimensional requirements, and branding needs.
What is the lead time for your investment castings for submersible pumps?
Our lead time for investment castings for submersible pumps is typically 30–45 days for the first batch. Subsequent batches take less time, subject to conditions.
What is the MOQ for your submersible pump castings?
Our MOQ for submersible pump castings depends on the components required, selected alloy, machining and customization requirements, and port of delivery. Please reach out to us for a tailored quote.
Do you only manufacture investment castings for submersible pumps?
