FAQs
Q: Are your pumps compatible with common SWRO membrane configurations?
A: Yes. Our pumps are designed for stable high-pressure output (up to 85 bar), making them fully compatible with leading SWRO membrane brands like DOW Filmtec SW30, Toray TM800, and Hydranautics SWC series. They support both 4″ and 8″ membrane housing layouts used in modular skid systems.
Q: Can the pump layout be adapted to fit my skid frame and piping design?
A: Yes. We offer full customization of inlet/outlet flange orientation, pump-motor alignment, and baseplate size. You can specify front, side, or vertical discharge — ideal for containerized or space-constrained layouts.
Q: Are these pumps suitable for solar-powered or off-grid RO systems?
A: Absolutely. With up to 92% hydraulic efficiency and compatibility with VFDs or soft starters, they are ideal for solar, diesel, or hybrid-powered systems. Low start-up torque and smooth pressure ramping protect the membranes in variable energy conditions.
Q: How long does delivery take, and do you support EPC project timelines?
A: Standard HPS RO Pumps ship within 4–6 weeks. Custom builds may vary depending on configuration.
