Stainless steel vortex water pump

Compact, stainless-steel single-stage vortex pump designed for reliable circulation and transfer of clean liquids in industrial systems. The W-type vortex (cantilever) design features a vertically upward inlet and outlet and an impeller that can move axially on the shaft to maintain a controlled gap; the gap is adjustable with shims (paper pad) for simple performance tuning and wear compensation.

Key features

• Construction: Stainless-steel wetted parts for corrosion resistance and hygienic service. Single-stage cantilever / vortex impeller design.
• Seal options: Packing seal or single end-face mechanical seal to suit different service requirements.
• Mounting: Pump and motor pre-assembled on a common base for straightforward installation and alignment.
• Operating range: Temperature -20°C to 80°C; maximum fluid viscosity up to 5E; not suitable for liquids containing solid particles.
• Performance range: Flow rates from 0.7 to 14.4 m3/h; head from 20 to 105 m; motor power 0.75 kW to 11 kW; standard speed 2,900 RPM.

Applications

• Process water circulation and supply in chemical, petrochemical, textile and power industries
• Industrial boiler feed and heating-water circulation
• Water supply for high-rise buildings and municipal systems
• Fire protection systems and HVAC loop circulation
• Cooling circuits for manufacturing and refrigeration cycles
• Catering and sanitation (e.g., high-pressure tableware disinfection)

Advantages for B2B buyers

• Compact, lightweight footprint reduces installation space and simplifies retrofits
• Durable stainless-steel construction lowers maintenance frequency in corrosive or hygienic environments
• Axially free-moving impeller and simple shim adjustment extend service life and simplify on-site maintenance
• Available with mechanical seal option where leakage control is required

Typical model example: 50W-45. For selection, provide required flow (m3/h), total head (m), liquid temperature, and seal preference so the correct motor size and sealing arrangement can be specified.
