Inoxpa Hyginox SE series centrifugal pumps are compact, with hermetic connection and sanitary design. They are used in factories where sterile conditions are necessary when pumping non-abrasive liquids of low and medium viscosity (up to 200 Sp). The body and impeller are made of AISI 316L cold-pressed stainless steel, which makes it suitable for use as the main process pump in: dairy industry brewing, winemaking production of vegetable oil production of drinks, juices in other areas of the food industry pharmaceuticals cosmetic industry, etc. The liquid is allowed at a temperature of 120°C (140°C SIP, max- 30 min). Mechanical seals and others in contact with the product are made of EPDM. The default is: Single internal face seal EN 12756 l1k (according to FDA and EC 1935/2004). Moving part - Graphite (C). Immovable part - silicon carbide (SiC). Sealing elements – EPDM. Options: Friction pairs - SiC/SiC. Sealing elements – FPM. In our case, the cause of failure of the end seal of the pump Inoxpa 1G110-4452025CE EN12756 L1K MECHANICAL SEAL SIC/SIC/EPDM 25 FDA CE 1935/2004 (analog AESSEAL-B012-ADY1-025) became the so-called "dry run". The pump was running without fluid for some time, and the internal parts of the pump were subject to increased friction without sufficient lubrication. The resulting heat caused the seal to fail. Most dry run failures occur when the pump is restarted after maintenance without checking that the pump is completely filled with liquid. Just a few seconds of dry running can cause the mechanical shaft seal to most likely be permanently damaged! Inoxpa 1G110-4452025CE mechanical shaft seal required - contact BTS Engineering!
