Optional low temperature coolant circulation pump considerations
Low-temperature coolant circulation pump is to take the mechanical form of refrigeration cryogenic liquid circulation equipment, which can be combined with rotary evaporator, vacuum freeze-drying oven, circulating water vacuum pump, magnetic stirrer and other equipment to produce chemical reactions Homework and play a role in the storage of drugs, so highly respected. However, many consumers at the time of purchase due to the lack of professional and technical personnel guidance, a direct result of loss of production and cost waste, and some will have a safety accident, affecting the life of the pump. Therefore, it is very important to choose a safe and durable cryogenic coolant circulation pump. Buy low temperature coolant circulation pump considerations Low temperature coolant circulation pump purchase Points to note: First, we must first determine the temperature range used, different test requirements require the temperature is not the same, the lower the required temperature The more expensive the price; the second is to determine the volume of coolant, the larger the volume of coolant, the more cooling liquid installed, so the amount of cooling is also very large, and its price is very expensive; Third, is to look at the cooling water pump is corrosive environment? If you want to use stainless steel shell, if not on the use of engineering plastics on it. Some manufacturers of cryogenic coolant circulation pump can not directly into the liquid cooling bath, only the external cooling cycle. While some manufacturers have both the direct cooling liquid can be placed in the bath, but also an external cooling cycle. Large size with a bath, small size without a bath, like the size of the mainframe computer, customers should also pay attention to the purchase. In general the lower the temperature of the cryogenic coolant circulation pump the more expensive the price, the larger the price the more expensive, the price of stainless steel shell on the contrary, the price is relatively cheap, so be sure to pay attention to when buying. The above is the selection of low temperature coolant circulation pump should pay attention to the matter, I hope your purchase to provide some help.
