S-type single stage double suction centrifugal pump structure characteristics
1.Compact structure, beautiful appearance, good stability, easy to install.
2. The smooth operation and optimized design of the double suction impeller reduces the axial force to a low limit, and has excellent hydraulic performance of the blade profile, and by precision casting, the inner surface of the pump shell and the surface of the impeller are extremely bright with remarkable anti-cavitation performance and high efficiency.
3. The shaft bearing uses SKF and NSK bearings to ensure smooth operation, low noise and long service life.
4. BURGMANN mechanical seal or packing seal is selected for shaft seal. Can guarantee 8000 hours of operation without leakage.
5. The installation form does not need to be adjusted when assembling, and can be used according to the site conditions. Separate or horizontal installation.
6. Install a self-priming device to realize automatic water absorption, that is, no need to install the bottom valve, no need to vacuum pump, no need to backpour, the pump can start.
S-type single stage double suction centrifugal pump application range
The parts of the pump are pressed with stainless steel plate, made by laser welding, and there are a variety of grades of stainless steel available, so the SLG type pump is very widely used, mainly for conveying a variety of clean water and light corrosive liquid, can be used for residential water supply and pressurized industrial boiler water supply air conditioning system circulation experience water treatment and reverse osmosis system food industry, pharmaceutical industry water.
