lobe transfer pumps

Designed according to 3A standard, widely used for transfer viscous media in the food-processing, cosmetics and pharmaceutical industries. Horizontal TUL Series and vertical TUR series, different rotor shapes(tri-lobe rotors butterfly type rotors, etc.

Ransmission Section Selection:
● Motor + Fixed Ratio Reducer: this method of transmission is simple, the rotor speed is constant,
which also determines the flow rate is not adjustable.
● Motor + Mechanical Friction Type Stepless Transmission: this type of transmission is manually adjusted to achieve variable speed. It is characterized by safe and reliable, large torque, flow adjustable stepless. Disadvantages are non-automatic adjustment and more troublesome. The speed must be adjusted in the working process, and it must not be adjusted under stop state. Please refer to the manufacturer’s instructions for use and maintenance
specifications.
● Converter Motor + Converter: the speed can be automatically adjusted in this way, which means that the flow can
be adjusted steplessly. The advantage is that the degree of automation is high and the low speed torque is large; the disadvantage is that the price of the inverter is relatively high. Please refer to the manufacturer’s instruction manual for maintenance specifications.

Rotor pump is also named rotary lobe pump, three-lobe pump,sole pump,etc. When the 2 simultaneous reverse rotating rotors(with 2-4 gears)revolve, it produces suction force at the inlet(vacuum),which intakes the material delivered.The 2 rotors divide the rotor housing into many smaller parts and revo-Ive in the sequence of a→b→c→d.When it revolves to position a,only housing I is filled with medium;when it revolves to position b,housing B encloses part of the medium,when it goes to position c,housing A encloses medium,and finally it goes to position d,then housing A,B and II are interlinked and the medium is transported to the outlet.As this process is repeated，medium(material) is transpor-ted continuously.
