Liquid caustic transfer pump

Liquid caustic transfer pump in sulfonate industry Lobe pump can be used to transfer liquid caustic in sulfonate industry. Considering corrosivity of caustic, special wetted parts will be used for this working conditions. We have more experience on this working conditions, and have speical design of pump structure and mechanical seal, can keep the pump in longer using life. So, we obtained patents of our-own design.   Pump pic for reference as below:
