| Structural | Gap is kept between the rotors and between the rotors and the pump body, no friction, long life. | There is a certain gap between the screws, but the wear of the front axle sleeve will cause the wear of the screw, the gap will become larger, and the flow rate and efficiency will decrease. | Rubber stator is easy to wear. |
| Simple structure, low failure rate and convenient maintenance. | There is a shaft sleeve in the front section, which is easy to wear and tear. The pump needs to be disassembled for replacement, and the maintenance is complex. | There is a shaft sleeve in the front section, which is easy to wear and tear.

| working principle | The rotor pump adopts two synchronous rotors. The rotor is driven by a pair of synchronous gears in the box. Driven by the main and auxiliary shafts, the rotor rotates in the opposite direction synchronously, which changes the volume of the pump, thus forming a higher vacuum degree and discharge pressure. | A plurality of closed volumes are formed between the meshing screws and the shell, and each closed volume is one level. When the transmission shaft drives the main screw to rotate clockwise, the closed volume at the left end gradually forms, and the volume increases to the oil suction chamber; the closed volume at the right end gradually disappears, and the volume decreases to the oil pressure chamber. | |
Product features:
1. Gap is kept between the rotors and rotors & pump body, no friction, long using-life.
2. Simple assembling and disassembling, easy to maintenance and clean, less easily-damaged parts.
3. High efficiency and energy-saving, low failure, reliable sealing and low noise.
4. In the same type pump, different type rotor can be interchanged.
5. Capable to pmp the viscous medium from 1cp to 2million cps.
6. Capable of pumping mixture of gas, fluid and solid medium.
7. Equipped with inverter, the flow can be adjusted as requirement of end-user.
8. Flange, screw or clamp connection can be selected as required.
9. Higher hygienic grade, support CIP, SIP. The surface roughness is 0.2--0.6mm, got 3A, FDA certification.
10. Hygienic safety valve is built-in structure.
