Mini Diaphragm Liquid Pump 7121

The 7121 series is a high-performance micro diaphragm pump independently developed by Keyto, which can realize the liquid line suction function. It is mainly used for cleaning, waste discharge, reagent mixing, vacuum creation and other working conditions within the instrument. The biggest advantage of this product is its long service life. It provides a variety of brushless and brushed versions to choose from. The brushed diaphragm pump supports a continuous working life of 3,000 hours and the brushless diaphragm pump supports a continuous working life of 10,000 hours. Secondly, the product has a variety of sealing materials to choose from, including EPDM ethylene propylene rubber, FKM special fluororubber and PTFE coating solutions; it has good sample reagent tolerance, and low vibration and noise. It is widely used in medical equipment, environmental protection equipment, instrumentation, mechanical chemical industry, laboratories and other fields.
