Cooling Tower Pump Cooling tower water circulation pumps are critical to the chiller system they serve. Your chilled water system may even have more than one type of chilled water pump, with one main pump circulating water through the chiller and another main pump circulating water through the building. All chilled water or condensate pumps should have good seals, bearings, rotating parts and drive motors. Both circuits have controls, bypasses and valves that are often overlooked during inspection and maintenance. Pump filters should also be clean. Characteristics Of Cooling Tower Pump a.Stable operation: the absolute concentricity of the pump shaft and the excellent dynamic and static balance of the impeller ensure smooth operation without vibration. b.No leakage: cemented carbide seals of different materials ensure no leakage of different media. c.Low noise: the water pump supported by low noise bearing runs smoothly, and there is basically no noise except the weak sound of motor. d.Low failure rate: the structure is simple and reasonable, the key parts are equipped with international first-class quality, and the trouble free working time of the whole machine is greatly improved. e.Easy maintenance: easy to replace seals and bearings. f. Less land occupation: the outlet can be left, right and up, which is convenient for pipeline layout and installation and saves space.
