OS Split Case Pump Structure Features

1. Compact structure, nice appearance, stable, easy to install
2. Stable operation、the optimized design of double suction impeller minimizes the axial force. The impeller is cast to shape. Its blade has excellent hydraulic performance. The internal surface of the pump shell and the surface of impeller blades are not only very smooth, but resist cavitation very well, and work with high efficiency.
3. We use high quality SKF and NSK bearing, ensuring stable operation, low noise and long service life.
4. BURGMANN mechanical sealing or packing seal method is used for shaft seal, ensuring 8000 hours of leak proof operation.
5. No further adjustment is needed in installation. You can install it in horizontal type or vertical type according to the specific condition of the site.
