As these pumps are smaller in flow and work at lower pressures to an irrigation pump or a commercial pump, then there is less chance of damage occurring and they generally don't cycle as much. As well as that, most house pumps these days also are controlled by electronic pressure controllers ( or press controls) and these also measure water flow too so they don't cycle as rapidly.

Peristaltic pump in motion. A peristaltic pump, also commonly known as a roller pump, is a type of positive displacement pump used for pumping a variety of fluids. The fluid is contained in a flexible tube fitted inside a circular pump casing. Most peristaltic pumps work through rotary motion, though linear peristaltic pumps have also been made.
Dynamic pumps are classified into different types but some of them are discussed below like Centrifugal, Vertical centrifugal, Horizontal centrifugal, Submersible, and Fire hydrant systems. 1). Centrifugal Pumps. These types of pumps are most commonly used worldwide. The working is very simple, described well and carefully tested.
Pump manufacturers provide information on the performance of their pumps in the form of characteristic curves on head versus capacity, commonly known as pump curves. By superimposing the characteristic curve of a centrifugal pump on a system-head curve, the duty point of a pump can be determined.
