Project: Bonve chemical grade pump used to transfer High Corrosive Polymer solution

A chemical company in Russia used Bonve lobe pump for their Polymer solution transfer. The product is very high corrosive with PH of 3. In 2017, the customer ordered one unit pump with material of stainless steel 316L. After one year's running, pump part of rotors appeared corrosion and pump performance reduced. In 2018, the customer started to do the test on different material and found out the suitable material. They ordered one pump with 904L. In 2020, the customer confirmed us the pump worked very fine. Till now, they have ordered our Bonve lobe pump 18units in total.

Below is the duty information and customer's feedback

Bonve offers its chemical grade rotary lobe pump, which is an ideal choice because of the below main features.

  • All contact parts (except seal rings) are made of super stainless steel, high corrosion resistance and abrasion resistance.
  • 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, ensure the instant temperature.
  • Effectively to transfer the polymer solutions at different viscosity.
  • Low noise, no vibration, energy saving, low maintenance.
  • Simple assembly and disassembly, no wearing parts except o-rings.
  • Pump flow can be adjusted at will by VFD.
