Introduction
The Horizontal Cooling Tower Pump is a horizontal centrifugal pump for cooling tower circulation systems, providing stable high flow rates and highly reliable continuous operation.
Products Advantages
Multiple Material Options Available
Choose from FC200, SUS304, SUS316, and SUS316L. Suitable for circulating water environments with pH 5–9 and temperatures ranging from 0–80℃, as well as mildly corrosive environments, offering enhanced corrosion resistance and longer lifespan.
Reliable Continuous Operation
Designed for S1 continuous duty and a 3φ 380V 50Hz standard, the motor can operate stably in environments from 0–40℃, meeting the 24-hour operation requirements of cooling towers.
More Stable Operation
Designed for liquid densities ≤1.05×10³ kg/m³, resulting in low vibration and low load, extending the service life of bearings and mechanical seals.
