High Head Stainless Multistage Borehole Pump

Global water treatment and borehole pump industries witness rising demand for sanitary, low-maintenance pumping equipment, pushing All Stainless Steel Pump market share upward year after year, while heavy, rust-prone cast iron pumps gradually exit mid-end residential and agricultural projects. For 6-inch small-diameter boreholes, oil-filled submersible motors outperform water-cooled motors because they do not rely on surrounding well water for heat dissipation, suitable for shallow and deep wells with unstable water levels. The 17m³/h flow grade fills the market gap between mini household pumps and large industrial borehole pumps; the High Head Stainless Multistage Borehole Pump becomes the preferred compact pumping unit for decentralized small water intake scenarios. Overseas buyers increasingly prioritize all-stainless steel oil-filled pumps to reduce frequent maintenance and part replacement costs over the equipment lifecycle.

1. Full All 304 Stainless Steel Sanitary Construction. No cast iron parts, anti-rust, anti-scaling and free of secondary water pollution, fully safe for domestic drinking water supply. Far longer service life than ordinary cast iron type.
2. Stable Rated Flow of 17m³/h Hydraulic Design.Optimized multi-stage centrifugal flow channel keeps steady 17 cubic meters per hour constant water output under fluctuating water levels and different lifts.
3. Standard 6 Inch Outlet Water Pump. Uniform 6-inch outlet flange design conforms to global pipeline standards. As a standard 6 Inch Outlet Water Pump, it connects directly with common water supply pipes without extra conversion adapters, simplifying on-site installation work greatly.
4. Fine Sand Resistant Structure Adaptable to Complex Groundwater. Thickened dense stainless steel inlet filter screen plus precision polished hydraulic components block tiny sediment and fine gravel in boreholes.
