Product Description
The DLSB-20/30 series low temperature coolant circulation pump is also known as low temperature cooling water circulation pump, cryogenic pump, low temperature circulation pump, low temperature cooling circulation pump, etc. The water tank volume is 24.38L, and the minimum no-load temperature can meet -30°C. On the basis of refrigeration, a water circulating pump is added to enable the cooled liquid to pass through the pipeline for external and internal circulation, and can provide low temperature liquid for external equipment such as a double-layer glass reactor, an organic synthesis device, a rotary evaporator, etc. It can also be combined with a rotary evaporator, a vacuum freeze drying oven, a water circulating vacuum pump, a magnetic stirrer and the like to perform multi-functional chemical reaction operations and drug storage at a low temperature.
The DLSB-20/30 series low temperature coolant circulation pump can maintain constant current and pressure. The circulating fluid can provide cooling water to meet the requirements of temperature and water purity, for large equipment such as high purity metal, rare substance purification, environmental experiment and magnetron sputtering, vacuum coating, etc. The low temperature coolant circulation pump can also meet the cooling needs of electronic instruments, electronic probes, ultra-high vacuum sputtering instruments, X-ray machines, lasers, accelerating leveling lamp and other valuable equipment. It is especially suitable for chemical, biological and physical laboratories that need to maintain low temperature and normal temperature conditions. It is an essential equipment for medical and health, chemical industry, food industry, metallurgical industry, colleges and universities, scientific research, genetic engineering, polymer engineering and other fields. ( The large-capacity low-temperature coolant circulation pump can be customized according to user needs.)
