Precise Modeling And Engineering Practice Of Sanitary Centrifugal Pump Installation Height Based On Npsh

6. The addition of a self-priming device can realize automatic water absorption, that is, it can be started without a bottom valve, vacuum centrifugal pump sanitary or backfilling. hygienic pumps. 72m, single-stage double suction hygienic pump, single-stage double suction
hygienic pump for food processing is a new type of high-efficiency and energy-saving water hygienic centrifugal pump. Under the same energy consumption conditions, its operating efficiency can be nearly 20% higher than the original water sanitary gear pump. 1. Compact structure, beautiful appearance, good stability, easy installation. 2. The optimized design of the double-suction impeller, smooth operation, reduces the axial force to a minimum, and has a blade shape with excellent hydraulic performance. After precision casting, the inner surface of the shell and the impeller surface are extremely bright, with significant anti-cavitation performance and high efficiency. 3. The bearings use SKF and NSK bearings to ensure smooth operation, low noise and long service life. 4. The shaft seal is BURGMANN mechanical seal or packing seal. It can guarantee 8000 hours of leakage-free operation.
