What is the difference between positive displacement pump and centrifugal pump?

Volumetric pumps are proportional to the speed and flow, such as gear pumps. Screw pumps, piston pumps, such as their rotation speed of 100 cubic meters when the flow, while the 1000 rpm can be understood as 10 cubic, but the actual efficiency Losses, traffic is about 9.5-9.8 cubic meters. Centrifugal pump by motor high-speed rotation of the medium (usually less viscous medium: water, diesel, kerosene, gasoline, etc.) by the impeller runner to throw out the medium. There are volumetric pumps can transport medium viscosity is relatively large, such as heavy oil, viscous oil, asphalt and other viscous medium; Centrifugal pump can only transport some of the less viscous medium, and his delivery viscosity can only be less than 3Cst ).

Diaphragm pump

The micro Diaphragm Pump produced by our company has compact structure, long service life, convenient maintenance, safe and reliable use. The medium conveyed by the pump will not touch the air valve, and can convey viscous liquid. Even if it is idling, it will not have any influence on the pump. This is the advantage of this pump.


Diaphragm pumps have a wide range of applications, and friends who are interested are welcome to consult and purchase!
