Dlsb low-temperature coolant circulating pump, also known as refrigeration pump / low-temperature pump / low-temperature circulating pump / low-temperature constant temperature reaction bath, is a high-precision constant temperature source with its own refrigeration, and has the function of a small chiller. It is widely used in research departments of petroleum, chemical industry, metallurgy, medicine, biochemistry, physical properties, testing and chemical analysis, colleges and universities, factory laboratories and Metrology and quality inspection departments. According to the size of the opening of the bath, the constant temperature experiment can be carried out in the bath, and it can also be connected with other equipment through a hose, which can be used together with the constant temperature source.

● internal circulation: cyclic huff and puff of liquid medium in the tank through the pump to increase the uniformity of temperature in the tank and reduce temperature fluctuations.

● external circulation: through the circulation capacity of the pump, the water outlet is used to connect the insulation hose with the external equipment to form a closed loop, which flows back to the water inlet of the equipment. It is to introduce the constant temperature medium in the tank and establish an external constant temperature field.
