For lobe pump with motor, there are two types:

● Mechanical stepless speed regulating lobe pump: the output speed can be adjusted by rotating the hand-wheel to control and regulate the pump flow

● Variable frequency speed adjustable output lobe pump:
1)fixed speed output ratio: speed is not adjustable, must pay attention to speed when selecting model

2) Variable frequency speed adjustable output: speed can be adjusted by frequency converter, if need to change speed, must configure frequency converter

Donjoy mechanical stepless speed regulating lobe pump composed of a lobe pump and a mechanical stepless gearbox---a motor and a reducer inside. The rotary speed of pump can be adjusted by rotating the hand-wheel as per the required condition. It has the advantage of simple operation, low cost and flexible applications, etc.
