What Are The Factors That Affect The Rotary Lobe Pump Speed

The rotor pump speed is the number of revolutions per minute of the pump shaft in r/min. The rated speed of the lobe pump is the speed at which the pump reaches the rated flow rate at the rated size. If the lobe pump runs beyond the rated speed, it will not only cause the power machine to overload or turn, but also the parts of the lobe pump will be easily damaged; the lobe pump's efficiency will be reduced if the speed is reduced. Under normal circumstances, the speed range of Ace lobe pumps is 10-650r/min.

Factors affecting lobe pump speed

1, viscosity affects the lobe pump speed

The operating speed of the pump needs to be selected according to the size of the medium viscosity, the higher the viscosity of the material, the lower the corresponding pump speed should be. The appropriate speed will enable the pump to obtain better results and longer service life, too high a speed will lead to pump operation cavitation, vibration and noise.

2、The solids content affects the lobe pump speed

The speed of the pump needs to be selected according to the size of the solids content of the medium. The higher the solids content of the material, the lower the speed of the pump should be. The right speed will enable the pump to achieve better results and longer service life, while too high a speed will lead to abnormal wear and tear of pump components, high failure rates and high maintenance or replacement costs.
