Heat transfer medium of the pump structure, materials, and auxiliary systems put a higher demand, water pumps, energy experts, energy-saving Technology Co., Ltd. Cheung Sha Haichuan talk about following the different requirements of temperature on the cooling pump and the company for:
 1. For the medium temperature is below 120 ¡æ, do not usually set up a dedicated cooling system, multi-media to use its own lubrication and cooling. Like the DFL (W) H chemical pump, DFL (W) PH shield chemical pump (more than 90 ¡æ, the protection shield of the motor should be H-level); and DFCZ common type and IH chemical pump allows the use of a suspension structure temperature Limit to 140 ¡æ ~ 160 ¡æ; IHF fluorine pump the maximum temperature up to 200 ¡æ; only CQB Magnetic Pump ordinary temperature does not exceed 100 ¡æ. It is worth mentioning that the particles crystallize or the media containing the sealing surface should be flush with pipe (the design of the interface are left.)
 2. For more than 120 ¡æ, 300 ¡æ within the media, the general cooling in the pump chamber cover shall be provided, seal chamber should also be connected to the cooling liquid (should be fitted with double mechanical seal), when the media is not allowed when the cooling fluid into Should be taken to their cool media access (which can be achieved by simple heat exchanger.) The company has DFCZ type of chemical process pumps, GRG HPK heat pumps and hot water pipe circulation pump (under development) are available for selection, another CQB-G can be used for high temperature magnetic pump less than 280 ¡æ high temperature media.
 3. For more than 300 ¡æ high temperature medium, some of the needs not only the pump head cooling, the suspension should also be equipped bearing room cooling system, pump structure generally as the center bearing, mechanical seals metal bellows type is best, but the price is high (Price is 10 times more common mechanical seal).
