Lobe structure:
1. Butterfly rotor pump: with butterfly rotor, it is superior to other rotor pump when transferring material with high viscosity and larger powder and effectively transports extremely stiff material.
2. Singe butterfly curved rotor pump (powder rotor pump): this pump series are specially design to transport material with larger powder. Its unique shape and curve makes it more outstanding compared to other pumps in delivering material with larger powders. It effectively prevents powders from clashing, which is the top choice of pumps transferring material with powders.
3. Tri-lobe pump: this is commonly type, the capacity and performance is better than other rotors. The shortage is high requirement to medium because its easy to damage grain medium.
Application :
edible vegetable oil pump, it's also called rotary lobe pump, three lobe pump, sole pump are widely applied in the beverage, food, dairy, pharmaceutical, chemical and process industries, to transport thick liquid material
