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.


Interchangeable


  • Interchangeable rotors, one pump multi-purpose.
  • Targeted seal for specific application, ensure zero leakage.


Easy maintenance


  • Compact structure, easy assembling and disassembling
  • Few wearing parts, low maintenance.


Long life


  • All main parts proceed by CNC, high precision fabrication.
  • No contact between the rotors, rotors and pump chamber.
  • Six bearings with separate arrangement, high balance.
  • Adjustable seal ring extends the shaft life.
  • Axis key synchronous 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.

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.
