Stainless steel positive displacement polyurethane transfer pump



Bonve stainless steel rotary lobe pumps are widely used in the chemical industry, due to the low speed operation, the pumps are particularly suitable for the medium that is easy to foam, high viscosity, high concentration and strong abrasion. Polyurethane are used in a wide range of manufacturing applications. They can be used for pressure sensitive adhesives, floor and carpet backing, and even paint to ensure it turns into a solid when spread into a thin layer. Bonve chemical grade lobe pumps are effective to transfer Polyurethane 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 steam or oil,ensure the resin can move smoothly at the appropriate temperature.
  • Effectively to transfer the resin 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.



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.
