Dalian Roland Pump Co., Ltd.


In the small power range, Roland magnetic pump is about 8~12% more efficient than comparable ordinary magnetic pump and canned motor pump; Compared with the mechanical seal pump, the efficiency is about 2% lower, and the efficiency will be about 6% lower when it is half away from the BEP point.

The overall efficiency of Roland high-power magnetic pump is basically the same as that of comparable mechanical seal pump.

(Explanation): The sliding bearing in the magnetic pump and the internal magnetic coupling produce friction loss, but the loss value is relatively constant. When the flow deviates from BEP point, the shaft power decreases, and the ratio of friction loss to shaft power increases compared with BEP point. When driving with high power, the ratio is small and can be ignored.

What are the differences between magnetic pump and centrifugal pump?

Magnetic pump is also a type of centrifugal pump. It is also called magnetic centrifugal pump, but magnetic drive centrifugal pump (referred to as magnetic pump for short). This pump applies the principle of modern magnetic mechanics


Eddy current loss of magnetic pump

The pressure bearing shell is commonly known as "isolation sleeve", and its installation position and working conditions determine the special requirements for material performance.


Sliding bearing problems

Therefore, the reliability of the sliding bearing is the key factor to ensure the continuous operation life of the magnetic pump unit.
