Medium Pressure

HSN Series
Universal three-screw pump with wide application
HSN
Product Features:

1. Advanced structure and excellent performance: The traditional high-pressure balance technique is changed, and the axial force balance of power and idler rotors at low-pressure is adopted, with even stress distribution, almost no deformation of screw, reliable and stable operation, no impulse, and low noise;
2. Unique design and reliable sealing: The mechanical sealing method is adopted for pump, with the sealing cavity interlinked to the suction; at the same time, the structure is designed to provide sufficient cooling cycle to the sealing, to ensure the sealing effect and no leakage;
3. Optimized improvement and aesthetic appearance: The traditional inlet and outlet positions are changed, so that they are located at both sides of the pump but in a straight line, resulting in a pleasing appearance; meanwhile, the design is innovated and therefore the inlet and outlet could be exchanged on user’s site without any change to pipelines;
4. Pump core assembly for convenient maintenance and accessory replacement: The pump is in a simple and compact structure, and the pump core assembly is in assembly construction; therefore, the pump core can be taken out as a whole, which is convenient for maintenance and repair;
