Polymer solutions transfer lobe pump with ATEX motor

Lobe pumps for Polymer solutions



Bonve chemical grade rotary lobe pumps are sucessfully to transfer polymer solutions due to the below main features. 


  • All contact parts (except seal rings) are made of super stainless steel, high corrosion resistance and abrasion resistance.
  • Elastic material is PTFE or FFKM, temperature resistance is upto 280C degree.
  • Gap is kept between the rotor and rotor, rotor and pump chamber, no friction and long service life.
  • Targeted seal structure and material used to make sure no leakage trouble.
  • Jacket design to run cold or hot liquid to ensure a consistant pump temperature.
  • Effectively to transfer the polymer solutions at different viscosity.
  • Low noise, no vibration, energy saving, low maintenance.
  • Simple assembly and disassembly, nearly no wearing parts.
  • Pump flow can be adjusted at will by VFD.
  • ATEX approved motors.


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.
