The difference between mixed flow pump and rotor pump

lobe pump

1.Working Principle

Mixed Flow Pump: After the impeller is rotated by the prime mover of the mixed flow pump, the action on the liquid is Very large, both centrifugal force and axial thrust, belonging to the centrifugal pump and axial flow pump, is a kind of pump between the centrifugal pump and axial flow pump, mixed flow pump between 300-500, between the centrifugal pump, axial flow pump.

lobe pump: lobe pump is a volumetric pump, the pump flow is positively correlated with the speed, mainly relying on the generation of negative pressure way to transport media, with the characteristics of high flow, low speed, high head.

2. Scope of use

Mixed flow pump: mixed flow pump is mainly used to transport clear water, but also used to transport the concentration of not more than 3% pulp or PH = 3 ~ 10, fiber length of less than 80mm solution, as well as other liquids with physical and chemical properties similar to water, it should be noted that the temperature of the liquid being transported is preferably It should be noted that the temperature of the liquid to be transported should preferably be less than 50°C.

lobe pump: lobe pump can be used to transport all kinds of media, the scope of use will be more extensive, and can achieve gas-liquid mixed transport and idle suction.

3. Performance range

Mixed flow pump: the performance range of mixed flow pump is as follows: flow rate 180~900m³/h, head 3~12.5m, inlet diameter 150~300mm, supporting power 4~30kw, etc.

lobe pump: lobe pump flow 0-2000m³/h, self-priming height 8.7m, pipe diameter DN25-DN450.

What is the difference between mixed-flow pump and lobe pump is introduced to you here, mainly from the working principle, use range, . Performance range and other aspects of the difference.
