Product Description
Stainless steel self-priming pump is a special pump optimized based on the principle of centrifugal pump. It achieves "dry start" through a unique gas-liquid mixing and separation structure, without the need for water injection or installation of bottom valves. Its core components (pump body, impeller, etc.) are made of 304/316L stainless steel, which combines corrosion resistance and structural strength, and is suitable for complex medium transportation.
Working principle: Before starting, a small amount of liquid is pre stored in the pump chamber, and the impeller rotates to form negative pressure, which mixes the gas and liquid in the suction pipeline; After the gas-liquid mixture enters the separation chamber, the gas escapes and the liquid flows back to the impeller to participate in mixing again. It circulates until the gas is exhausted and enters the normal water delivery state.
Structural composition: including motor, stainless steel pump body, impeller (flexible or rigid design), mechanical seal, gas-liquid separation chamber. Specially designed volutes or diffusion tubes enhance self-priming efficiency, and quick detachable structures facilitate cleaning.

Feature:
Strong corrosion resistance:
304/316L stainless steel material can withstand corrosive media with pH 1-14 (such as acid, alkali, organic solvents), and its service life is significantly extended compared to cast iron pumps.
Excellent self-priming performance:
The self-priming height can reach 6.5 meters, and the suction can be completed within 30-90 seconds after starting, without the need for bottom valves or vacuum assisted equipment.
Wide adaptability to media:
It can transport gaseous liquid (such as foam), mild paste slurry (solid content ≤ 15%), and media containing solid particles (particle size ≤ 60% of pipe diameter).
Efficient energy saving and low maintenance:
Hydraulic optimization design improves efficiency (55% -68%) and reduces energy consumption by 20% -30%; The mechanical seal has a long service life and supports quick disassembly and replacement.
Safety and Convenience:
Compact and lightweight structure (reducing weight by 30% compared to traditional pumps), supporting the selection of explosion-proof motors; Operating noise<75dB, minimal vibration.
