SN Positive Displacement Horizontal Triple Screw Pump

>> Features

1. Advanced structure and excellent performance: The traditional high-pressure balance technique is replaced with a low-pressure axial force balance system for power and idler rotors, ensuring even stress distribution, minimal deformation of the screws, stable operation, no pulsation, and reduced noise.
2. Unique design and reliable sealing: The pump uses mechanical sealing, with the sealing cavity connected to the suction side. A cooling cycle is designed into the structure to ensure effective sealing and prevent leakage.
3. Optimized design and aesthetic appearance: Inlet and outlet positions are reconfigured to be on opposite sides in a straight line, improving aesthetics. The design allows for easy swapping of inlet and outlet without changing pipelines.
4. Easy maintenance with pump core assembly: The compact and simple structure allows the pump core to be removed as a whole, making maintenance and repairs more convenient.
5. Pressure relief valve for pump protection: The built-in valve provides transient protection against overload, though it is not intended for use as an overflow valve.
6. Flexible inlet and outlet configurations for easy piping installation.
7. Multiple mounting options to suit different working conditions.


>> Usage:
Ideal for handling oil and lubricating media. Suitable for viscosities ranging from 1cst to 760cst, and temperatures below 150°C. Flow rates range from 0.3m³/h to 321m³/h, with heads up to 4MPa.
>>> Application:
