The rotary pumps have less spare parts, simple maintenance and low cost, long service life and so on.They are very well used in the paper-making industry, by more and more people choose. It has gradually replaced the screw pump in many working conditions of paper making industry.
Rotary pumps maily used following positions:
Preparation of starch glue and feeding and conveying of starch.---- S.S. lobe pump
Coating preparation and coating feeding and transportation.---- S.S. lobe pump
Chemical unloading and chemical addition.---- S.S. lobe pump

| Working Principle of Lobe Pump | ||||||
| Twin-Rotary pumps are multi-functional and bi-directional positive displacement pumps, produced with fine technology. The manufacturing engineering and precision of the pumps approach the advanced level of the world. Rotary pumps use synchronic rotors, driven by a pair of synchronic gears in the gear box. Transmitted by the main shaft and the sub-shaft. The rotors move synchronically in counter-clockwise directions, which, consequently, varies the pump capacity and builds up high vacuum capacity and emission pressure. It is particularly suitable to pump sanitary medium, high-corrosive and high-viscous medium. |
