Engineered Specifically for Cooling Towers
Our Cooling Tower Circulation Pump is designed exclusively for cooling tower systems, not as a general-purpose water pump. Towers require low head pressure and high water flow, and conventional pumps waste energy.
- Water flow: 5–1,200 m³/h
- Head pressure: 12–50 m
- Works for open and closed cooling towers
- Saves 5–8% electricity compared to standard pumps
- NPSH: 2.5–4.0 m, reducing cavitation and extending pump life
Long-Life Seals and Bearings
- Mechanical seal: SiC-SiC with Hastelloy C-276 spring, lasting 12,000+ hours
- Bearings: SKF or NSK, rated for 60,000 hours (L10)
- Pump shaft: 2Cr13 stainless for iron pumps; 316L for stainless models
- Motor: IE3 efficiency, IP55 protection, Class F insulation
- Inlet screen included; Y-strainer recommended to protect the pump
Tested for Performance and Reliability
