Displacement Positive Pumps for Paper Coatings
Paper Coatings Pumps
Application for Paper Coatings
Industry
Bonve pumps are to be found in numerous processes, where their reliable low shear flow characteristics are ideally suited to the transfer of paper coatings. We select the pump according to the characteristics of paper coatings and condition of the technological requirements, bring you the best pump for your critical process. Bonve conducts analysis and research on coatings and has developed Paper Coatings Pumps.
Typically pumped media: Calcium Carbonate(up to 70% solid content), Coatings (Pre-Coating,
Intermediate Coating, Top Coating, Back Coating).
Applications: Up loading, Transfer.
Bonve offers the broadest range of its Rotary Lobe Pumps for paper
industry. As an excellent pump manufacturer, our hard technical barriers have
become a powerful help for our Bonve pumps reform and innovation. So far, Bonve
pumps have developed to the fourth generation and are mature.

adjustment, no rotor collision problem.
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.

Main Parts of the Complete Pump
Bonve complete pumps are usually composed of bare shaft pump,
coupling and its guard, geared motor and baseplae. With your order, bare shaft
pump or complete pump is supplied.
Bare Shaft Pump Structure
Based on the port direction, we have the pump with horizontal
port and vertical port to meet your site installation.

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.
