Product Q&A

Q:What's the energy-saving advantage of LQDMF permanent magnet variable frequency pump?

Adopts IE4 ultra-high efficiency permanent magnet synchronous motor with integrated intelligent VFD drive. It automatically adjusts rotating speed based on actual water demand, saving over 30% power consumption compared with traditional fixed-speed pumps, and realizes stable constant pressure water supply without pressure fluctuation.

Q:What material are the pump's wetted parts? Is it suitable for drinking water?

All fluid contact parts are made of SS304 stainless steel, smooth inner flow channel, rust-proof, anti-corrosion, no secondary water pollution. It fully meets domestic pure water, building water supply and light industrial clean water transportation requirements. We can upgrade to SS316L for weak corrosive liquid on request.

Q:Can this pump work with different voltage & frequency for overseas markets?

Yes. We support customized single/three-phase voltage (220V/380V/415V) and 50Hz/60Hz frequency to match global power grids. The built-in intelligent driver supports wide voltage range, and the digital panel can display real-time pressure, flow and fault codes.

Q:How long is the warranty period of LQDMF pump? Do you supply spare parts?

Standard warranty is 18 months after shipment or 12 months after installation, whichever comes first. We provide complete spare parts including mechanical seal, impeller, motor and controller at factory cost after warranty, and offer remote technical guidance for installation & troubleshooting.

Q:Can you customize pump parameters or print customer logo for OEM orders? What info do I provide for quotation?

We accept OEM & ODM service, support logo printing, customized pump head, flow rate and packaging. To get accurate quotation, please offer required flow, head, medium temperature, voltage, frequency and usage scenario. MOQ is flexible for trial orders.
