Lobe pump is a positive displacement pump. The left cam is driven by the drive shaft and the right cam is mounted on the drive shaft and driven by the gear. The two cams rotate synchronously without interfering with each other. 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 variable frequency speed adjustable output lobe pump has many configurations for pumps and frequency converters.
Motor: ABB/SEW/Siemens, domestic brand optional
Frequency converter: Delta, Siemens, SEW, domestic brand optional
