1. The rotor is processed by high-precision grinding, with a profile error of less than 0.01mm and a surface roughness of up to RA 0.8μm.

2. Adopting hydraulic automatic balance, with low vibration and low noise.

3. The product has the advantages of stable pressure output, no pulsation, high efficiency and strong self-priming ability.

4. The product parts adopt modular design and have two installation methods (horizontal and vertical) to meet different needs.

5. The product has a compact structure, small size and light weight, and can work smoothly at higher speed and pressure.

6. The pump body adopts a welded structure, and the liner is made of ZCuSn5Pb5Zn5 tin bronze material. The connecting flange adopts a concave convex flange type, which can effectively prevent the misalignment and detachment of the sealing gasket.

7. Screw pump can be designed according to CE, API676 and other international standards.
