SN Positive Displacement Horizontal Triple Screw Pump

>>> Features

1. Advanced structure and excellent performance: The traditional high-pressure balance technique has been replaced with a low-pressure axial force balance system for power and idler rotors. This ensures even stress distribution, minimal deformation, reliable operation, no vibration, and low noise;
2. Unique design and reliable sealing: The pump uses mechanical sealing with an interconnected sealing cavity to the suction side. It also includes a cooling cycle design to maintain sealing efficiency and prevent leaks;
3. Optimized appearance and user-friendly design: Inlet and outlet ports are now located on both sides in a straight line, making the pump more aesthetically pleasing. This allows users to easily switch inlet and outlet positions without changing pipelines;
4. Easy maintenance: The pump core is designed as an assembly unit, allowing it to be removed as a whole for convenient repairs and replacements;
5. Pressure relief valve: Provides temporary protection against overload, though it should not be used as an overflow valve for the pipeline;
6. Flexible inlet and outlet configurations: Offer various combinations for easier piping installation on-site;
7. Multiple mounting options: Suitable for different installation requirements in various working environments.
