Difference between cold water pump and hot water pump

Commonly used cold water pump refers to the pump can transport liquids below 80 ° C called the cold water pump, the temperature between 80 ° C to 120 ° C called the hot water pump. Now to say the difference between cold water pump and hot water pump. The difference between cold water pump cold water pump and hot water pump 1, the characteristics of cold water pump Cold water pump commonly used seal packing or NBR rubber mechanical seal, the most commonly used packing sealed pump IS single-stage single suction centrifugal pump The pump Is also the earliest cold water pump products, as the filler itself requires liquid cooling lubrication, so the pump is the highest temperature resistance of only about 80 degrees, and packing sealed cold water pump there is the phenomenon of drip, the pump base and the pump have a certain environment around Of such products have been gradually replaced by ISG and ISW centrifugal pump series, ISG and ISW series of cold water mechanical seal it will not leak phenomenon, and are all used in the direct structure of the impeller on the motor shaft , Above the noise and vibration is superior to the old IS series of cold water pump This type of pump products are commonly used in air-conditioning water cycle so it is also known as air-conditioning chilled water circulation pump. 2, the characteristics of hot water pump Hot water pump is ISG and ISW centrifugal pump series based on the optimal design of the hot water pump products, especially IRG hot water circulating pump the largest amount, because the pump uses vertical motor The upper part, there is a short bracket between the pump and the motor, will not cause the motor water to burn out the motor due to the leakage of the mechanical seal, and can also be designed as a mechanical seal on the basis of the IRG hot water pump and tap water Cooling device hot water temperature pump products can reach the maximum temperature of 240 degrees.
