A compact, stainless-steel self-priming jet pump engineered for clean-water applications and light industrial pressurization. This horizontal, single-stage end-suction centrifugal unit uses a closed impeller (available in reinforced engineering plastic or stainless steel) and a SUS304 pump casing and cover fabricated by precision welding and annealing to reduce stress and extend service life. The integrated jet injector is molded from high‑strength, heat‑resistant engineering plastic to deliver reliable suction performance and re-priming capability.
Key features
- Closed impeller design for efficient hydraulic performance and reduced cavitation risk
- Wetted parts in SUS304 stainless steel; impeller selectable in SUS or reinforced plastic for application-specific corrosion/wear resistance
- Jet injector made from heat‑resistant engineering plastic for durable suction assistance
- Precision welded and open‑flame annealed casing to relieve fabrication stresses and improve dimensional stability
- Lightweight, low-noise construction with low vibration and long operational life
- High suction capability and reliable self-priming behavior — suitable where periodic priming is required
- Motor: aluminum shell, B‑class insulation, IP55 protection; single‑phase versions can include an internal thermal (overheat) protector for safer operation
Suitable applications
- Domestic water supply and pressure boosting for small buildings, urban and rural households
- Industrial process water transfer, cleaning-system pressurization, and equipment or machine-tool supporting systems
- Food & beverage: transfer and filling of purified water, beverages and similar liquids (verify local hygienic/certification requirements for direct food contact)
- Medical and pharmaceutical: transport of process and pharmaceutical water (subject to regulatory compliance)
- Irrigation: small-scale farmland, orchards and garden sprinkler systems
- Chemical: handling of mildly acidic or alkaline liquids (confirm chemical compatibility for specific fluids)
Notes for buyers
- Designed for clean liquids; not intended for slurries or heavily contaminated fluids
- Select impeller material (stainless vs reinforced plastic) based on corrosion and wear considerations
- Ensure installation follows local electrical and piping codes; specify single‑phase or three‑phase motor configuration when ordering
- Regular inspection of seals, impeller and injector prolongs service life and maintains priming performance
This pump is positioned for OEMs, system integrators and facility managers seeking a compact, corrosion‑resistant self‑priming solution for boosting and transferring clean water in commercial and light industrial environments.
