>>>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;
5. Pressure relief valve for the protection of pump: The valve equipped on the product can provide transient protection to the pump, to prevent overload, however, it can not be used as the overflow valve for the pipe.
6. Various combinations of inlet and outlet, convenient for piping on site;
7. Various mounting available, to meet different mounting requirements in the working conditions.
