Products Details

Paper chemicals designate a group of chemicals that modify the properties of paper, which including Emulsions, Resins, Retention Aids, Sizing agent, Flocculating agent, Dry strength agent, Wet strength agent,Softening agent, Binders, Fillings, Cooked Starch, Coating Pigments, Anti-foaming agents, CMC, Polymers,Specialty Chemicals etc. These chemicals can be used to alter the paper in many ways, including changing its color and brightness, or by increasing its strength and resistance to water.

 

What pumps used to convey paper-making chemicals during production? Bonve Rotary lobe pumps are to be found in numerous processes, including the Coating kitchen, at the Sizing Press and on the Coating Section; all providing gentle handling of shear sensitive media and long trouble free service. We call these lobe pumps Paper chemicals transfer pump.

Pump working principle



Bonve lobe pumps are designed based on the exploration of more than 3,000 fluids in various industries. They are particularly, effectively pumping for High viscosity, High solids and Corrosive fluids.


Paper chemicals transfer pump


Bonve lobe pumps basically consist of two lobe rotors, which rotate synchronously driven by a pair of synchronous gears in the gearbox. The rotors are driven by the main shaft and sub-shaft to rotate in a synchronous reverse direction, which changes the pump capacity, builds up high vacuum and discharge pressure, thus an efficient pumping is formed. Gap is kept between the rotors and between the pump casing, no friction, long life, no damage, no physical and chemical reaction to the pumped products.

Special design



Seal Type: According to the different characteristics of the medium, you can have the Single-face balancing mechanical seal, Double-face water cooled mechanical seal, Heat resisting bellows mechanical seal, etc. Targeted seal used ensures zero leakage. All these types can be universally interchanged.
