Which pump type is known for having a hydraulic agitator?

The roller pump is recognized for its hydraulic agitator because it effectively moves fluid through the use of rotating rollers that compress a flexible tube. This design not only facilitates the movement of fluid but also creates turbulence, which is beneficial for mixing chemicals or suspensions within the liquid. The hydraulic agitator enhances the pump's ability to keep particles in suspension, thereby improving distribution and effectiveness in various applications, including pest control situations.

In contrast, other pump types like piston pumps and diaphragm pumps are more oriented towards generating pressure and flow without the same level of agitation, while centrifugal pumps rely on rotational energy from a rotating impeller to move fluid, which does not inherently include a hydraulic agitation feature. The roller pump's unique combination of pumping and agitating properties makes it particularly suitable for applications where thorough mixing is essential.
