Paper Pulp Transfer Rotary Lobe Pump With High Efficiency and
High QualityDifferent structure and material of mechanical
seal for paper coating, can extend service life of seal.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 more than 60 domestic and foreign paper
industry users, more than three thousand rotary pumps are procured
for use in paper making industry. Such as UPM, ECOLAB, GAW, Stora
Enso, Kemira, ASIA Symbol, Nine Dragons Paper, OJI paper, Lee & Man
paper, APP paper...... Now, we have a very mature R & D technology
and application technology,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 pumpCoating preparation and
coating feeding and transportation.----S.S. lobe pumpChemical
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.

Lobe PumpTwin-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. Technical
