How to choose Shanghai Bilang cryogenic coolant circulation pump.
The purchase of low-temperature coolant circulation pump: first of all, we must first determine the temperature range used, the temperature required for different tests is different, the lower the required temperature, the more expensive the price; the second is to determine the volume of the coolant , The larger the volume of coolant, the more coolant is installed, so the amount of cooling is also large, and its price is very expensive; the last thing is to look at the corrosive environment of the cooling water pump, if there is It is necessary to use a stainless steel shell, or engineering plastic if it is not available.
In short, the lower the temperature of the low-temperature coolant circulation pump, the more expensive the price, and the larger the volume, the more expensive the price. If you choose a stainless steel shell, the price will be expensive, otherwise the price will be relatively cheap; Take the Great Wall Instruments DLSB-series low-temperature cooling circulating pump as an example:
