How To Distinguish Rotary Lobe Pump And Gear Pump

Ace recommends that you start with the working principles and characteristics of both.

I. Working principle and characteristics of lobe pumps.

The lobe pump is driven by a pair of gears meshing to drive the two rotors, the purpose is to achieve synchronous reverse rotation, in the process of rotation of the inlet will produce a vacuum, so as to suck the liquid to be transported, this is a volumetric pump. It is characterised by its wear and corrosion resistant properties. The lobe pump is used for the transport of highly concentrated, viscous and hygienic materials in the food, chemical, pharmaceutical and other hygiene industries.

Second, the working principle and characteristics of gear pumps.

Gear pump is a volumetric rotary pump, there is a pair of meshing gears, one of the active gears is driven by the motor to rotate, the other driven gear and the production gear mesh and rotate, when the two teeth gradually separated will form part of the vacuum, the liquid in the atmospheric pressure through the suction tube to suck in the liquid, the liquid sucked in along the inner wall of the pump body by the gears squeeze out, features handling small, high head, very suitable for like soap horn, Silicone oil, rosin, paint, heavy oil and other viscous liquids, semi-solid high viscosity materials, is the first choice for the transport of these materials.

In short, whether it is a lobe pump, or gear pump, have their own unique characteristics, although both can be flat transport high viscosity material, but the gear pump shortcomings are not wear-resistant, unreliable operation, while the lobe pump operation process is basically no wearing parts, easy to clean, less maintenance, long life.
