Low Flow Deep Well Submersible Pump

This 2m3/h 90QJD Submersible Pump adopts food-grade 304 stainless steel stamping & welding, anti-rust and anti-corrosion for long-term underwater soaking. The motor chamber is filled with high-insulation transformer oil to realize waterproof oil-immersed sealing structure; core friction components use high-purity alumina ceramic bearings and ceramic impeller shaft sleeves, forming the core ceramic anti-sand structure.

3.5-inch 90QJD series oil-filled deep well pumps occupy the mainstream small-bore submersible pump market globally.High-head low-flow demand (2m³/h) for mountain water intake grows year by year, and clients are increasingly inclined to ceramic anti-sand oil-immersed models with stable heat dissipation. Conventional cast iron pumps have poor corrosion resistance, so all-stainless steel 90QJD products become the preferred replacement product for overseas small well water equipment.

1. Fixed 2m³/h low steady flow output, multi-stage high-lift design, ideal for mountain high-drop water transfer and small-volume water supply scenarios

2. Professional ceramic anti-sand construction, ceramic bearings & shaft sleeves resist sediment abrasion, reduce maintenance frequency and extend pump service life

3.90QJD 3.5-inch slim outer diameter, compatible with all standard narrow deep wells of 90mm inner diameter, wide well adaptability

4.Pure copper winding motor with low energy consumption, high conversion efficiency, save electricity cost for long-term use

5.Compact integrated structure, lightweight, easy to install, lift and maintain without complicated auxiliary equipment.
