FAQS
Frequently Asked Questions
Still have a question? Our field engineers reply within one business day.
How Fast Can You Deliver Replacement Parts?
Our standard lead time for custom replacement pump & compressor spare parts ranges from 4 12 weeks, subject to material availability, part complexity, casting / forging process and inspection requirements. For emergency breakdown cases, we offer expedited service: including laser cladding, shaft repair, impeller reconditioning and critical spare parts fast track production to minimize your equipment downtime.
Can You Reverse-Engineer a Part from a Sample or Drawing?
We support full reverse engineering based on physical samples, original worn components or legacy customer drawings. Our workflow includes 3D scanning, dimensional inspection, material analysis, FEA validation, and full size manufacturing. We can produce parts fully compliant with API standards to match original equipment performance. Typical lead times run 4 8 weeks depending on material, casting method and machining complexity. Urgent repair work — like laser welding or shaft restoration — can be fast tracked.
Which Materials Can You Cast and Machine?
We cover a wide portfolio of industrial alloys for pump and compressor components: carbon steel, stainless steels (304/316L, 904L), duplex & super duplex stainless steel, CA6NM, WCB, titanium alloy TC4, high temperature martensitic steels and various nickel base alloys. We are capable of investment casting, sand casting, forging plus precision CNC machining for impellers, casings, shafts, seals and rotating assemblies.
What Quality Documentation Do You Provide?
We supply complete quality documentation package upon request: material test reports (MTR), chemical & mechanical certificates, non destructive testing reports (NDT: UT/MT/PT), dimensional inspection records, heat treatment records, balance test reports, impeller overspeed test certificates and third party inspection documents. All records meet API requirements for global project deliveries.
Do You Handle Small Quantities or One-Off Prototypes?
Typical lead times run 4–8 weeks depending on material, casting method and machining complexity. Urgent repair work — like laser welding or shaft restoration — can be fast-tracked.
