What pump type is characterized by its low to mid speed of 200-1200 rpm?

The diaphragm pump is characterized by its ability to operate at low to mid speeds, typically ranging from 200 to 1200 RPM. This type of pump utilizes a flexible diaphragm that moves up and down to create a pumping action, which effectively draws fluid in and pushes it out as the diaphragm flexes.

Because of its design, the diaphragm pump is capable of handling various types of fluids, including those that are thick, viscous, or contain solids. The lower operating speed can be beneficial for maintaining a gentler flow and reducing shear stress on sensitive materials. This characteristic makes diaphragm pumps an excellent choice in applications where controlled doses or variations in flow are necessary, as well as in situations that require the handling of aggressive chemicals without the risk of leakage.

In contrast, the other pump types mentioned operate under different principles and speed ranges, which do not align with the specified 200-1200 RPM range. For example, centrifugal pumps typically operate at higher speeds to create the necessary centrifugal force for moving fluids. Piston pumps can have variable RPMs but are usually designed for higher pressures and specific applications. Roller pumps also operate at various speeds but are generally used for transferring fluids at higher rates. Thus, the diaphragm pump is uniquely suited to the characteristics
