Rotary Vane Vacuum Pump and Liquid Ring Vacuum Pump are two common types of vacuum pumps. They have some differences in terms of working principle, application fields, advantages and disadvantages, etc.
The cryogenic coolant circulation pump is a combination of a circulating pump and a cryogenic cooling pump. It is a good auxiliary equipment for vacuum distillation and vacuum concentration. It is especially adapted to be equipped with a rotary evaporator, which not only reduces the use space, but also reduces the vacuum degree and saves water resources. It is widely used in modern laboratories.
Large circulating water vacuum pumps are used in many industrial sectors such as petroleum, chemical, machinery, light industry, medicine and food. Circulating water vacuum pumps are widely used in many processes of industrial production, such as vacuum filtration, vacuum water diversion, vacuum feeding, vacuum evaporation, vacuum concentration, vacuum regain and vacuum degassing. The use of large circulating water vacuum pumps should not neglect some details. Pay attention to the following when using:
