Pump: Working Principles, Function & Diagram

The flow rate remains the same with positive displacement pumps regardless of the output pressure, unlike centrifugal pumps. So, the positive displacement pump falls into the category of constant flow pump equipment. As the pressure increases, however, the internal leakage will also increase slightly, resulting in a flow that is not truly constant.

Understanding Your Pressure Storage Tank | Horticulture,

One way to select the proper size for a pressure tank is to base it on the pump''s flow rate. A typical private water supply pump supplies water at a rate of 5 to 10 gallons per minute (gpm). Multiply the flow rate by four to determine the size of a diaphragm or bladder tank. For example, a 9-gpm pump would require a 36-gallon storage tank.
