BGLH 50-125A, 55, (11/16), 1,1kW, 2880 stainless in-line pump with tandem mechanical seal

A pump with a tandem mechanical seal for pumping mash, bards, alcohol, residue concentrate, paint, food products. Industrial pumps made of stainless steel AISI 304, (housing, shaft, impeller). On a standard BGLH pump, there is a single mechanical seal that works in a pumped medium with a high dry matter content, in contact with a friction pair, which burn and are deposited on the friction pair, creating a crust from flour, sugar, yeast, etc. Upgrading the seal with a chamber for cooling and flushing fluid, we eliminated this kind of problem by supplying water with a pressure exceeding the pressure in the working fluid pump. This seal is used when the supply of the sealing fluid to the seal is impossible. This mechanical seal is absolutely hermetic, but its service life is less than that of a double mechanical seal with a shut-off fluid. In addition, this seal interacts worse with abrasive-containing and crystallizing liquids.
