R&D evidence is mixed: a professional R&D department and ODM services are stated, but no new products were developed in the past year and no SDK is available. The supplier reports OEM service for popular brands but no Fortune 500 cooperation. Financial records are referenced for 2022–2024, but the slices do not provide enough detail to assess...

Product Q&A

Q:Why choose full stainless steel over cast iron or semi-stainless for saltwater?

For saltwater, full stainless steel (AISI 304/316) is crucial. Unlike rust-prone iron or semi-stainless, it offers corrosion resistance, longevity, and no rust contamination, ensuring lowest lifetime cost.

Q:Suitable for direct seawater or RO desalination plants?

Yes, designed for these tasks. Marine-grade stainless withstands seawater. Ideal for RO plants' high-pressure intake, brine transfer, or boosting. Use 316 for best chloride resistance.

Q:Custom pump configuration like different voltage or cable length?

Yes, as OEM/ODM, we offer custom voltage (380V/415V/480V), cable type & length, impeller material (SS304/SS316/bronze), and performance parameters. Contact for a quote.

Q:Handles other corrosive fluids besides seawater?

Yes, stainless steel suits mildly corrosive fluids, e.g., chemicals, wastewater, acidic/alkaline solutions, brackish water. Contact us with fluid details for confirmation.

Q:What is the warranty period and coverage?

Standard warranty is 12 months from delivery covering manufacturing defects only. Extended warranty up to 36 months is available as an optional plan.
