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.
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 Cooling Tower 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.
In industrial environments, cooling is a critical process to ensure equipment and systems do not overheat. Therefore, cooling pumps are often supplied in a duty/standby configuration, with a second pump providing backup to the main pump in case the main pump requires maintenance or, in the worst case scenario, fails.
Cooling water pumps often need to run continuously, which means they need to be extremely durable and often have larger 4-pole motors that run at half speed to reduce wear. For most industrial applications, long-coupled pumps are usually supplied as it reduces the risk of any fluid entering the motor if the mechanical seal fails.
Centrifugal pumps are often the cooling pump of choice due to their greater efficiency when handling low viscosity fluids such as water. While there is this similarity in cooling systems, the specific application at hand does mean there are some differences in the specifications of the pumps offered.
Power plant cooling tower
Power Plant – This is one of the easiest examples to imagine because everyone has seen the large cooling towers outside of a power plant. High flow, low head centrifugal pumps are commonly used to move large volumes of water into cooling towers.
Marine Engines – Engine cooling is an important process for ship safety and operation. Modern ships usually use a closed cooling system, which uses fresh water to directly cool the engine, and then uses seawater to cool the fresh water in the secondary exchanger. This system means that only seawater cooling pumps need to be manufactured from more expensive materials such as bronze or stainless steel that are compatible with corrosive salt content.
Manufacturing/Processing – Cooling of engines and gearboxes used in production lines, lifting equipment and any other large equipment operating in near-continuous operation.
HVAC – Unlike other mechanical examples, HVAC cooling units are designed to provide comfort to people, such as in hospitals, schools, and large commercial buildings. Such cooling water pumps are typically low head and low flow single stage centrifugal pumps as they tend to be smaller systems than industrial cooling.
