Rotary Lobe Pumps For Starch Adhesive
More often than not, when you check your front door, there’s another package waiting-usually in form of a cardboard box. The creation of cardboard boxes and other paper products relies on starch-based adhesives to hold things together. Bonve Rotary lobe pump has the ideal solution for pumping starch adhesive for the paper and corrugating industries.
In any case, the reliability of pump operation and low maintenance costs have become the most basic requirements. Bonve lobe pumps are widely used and recognized in the paper industry, thanks to the modular design, qualified material used, reliable sealing, no shearing, no pulsation, less wearing parts, and low maintenance.
About Starch Adhesive:
1.Raw starch is derived from plant.
2.Plants include corn, wheat, and potatoes.
3.Mixed in equipment commonly referred to as a starch kitchen.
4.Tend to be shear - thickening.
Industries of Starch Adhesive:
1.Corrugating adhesives
2.Bookbinding
3.Sizing & finishing of textiles
4.Paper cartons
5.Paper
6.Paperboard
Working Principle
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.

Note:
1. Tested medium: water. Your liquid's density, viscosity
and temperature are necessary to supply when choose the pump.
2. Speed, flow rate, electrical power and pressure will be
varified according to different liquid properties.
3. Port size can be changed as needed.
