Product Description
Sodium Hydroxide Transfer Lobe Pump/ Rotor Pump/ Rotary Pump
Paper making lobe pumps are widely used to transfer PAM, starch slurry, liquid rosin, rosin gum. paper slurry, dry-strength agent, wet-strength agent, sizing agent, defoaming agent, coloring starch, coating and so on.
We have cooperated with UPM, STORA ENSO, Ning Dragons Paper, OJI paper, Lee & Man paper, APP paper and so on for many years. Lobe pump is very well used in the industry and it has gradually replaced the screw pump in many working conditions of paper making industry. Lobe pump 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
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--0.8um, got 3A, FDA certification.
10. Hygienic safety valve is built-in structure.

| 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. |
