WebThis is known as the “shut-off head”, it’s the amount of head a pump can produce at zero flow. To choose your required pump, you need to know two things: the total head and what flow rate you require. As you might expect, these two quantities are related. The maximum head (shut-off head) is achieved at a flow rate of zero. Web22 mei 2024 · Suction cavitation, or also classic cavitation, occurs when a pump is under low pressure or high vacuum conditions. It is also called inadequate NPSHa cavitation. Thermal Engineering Suction Cavitation Suction cavitation, or also classic cavitation, occurs when a pump is under low pressure or high vacuum conditions. clara barthez instagramWebYour pump will need at least 30 ft. plus the friction loss to get the required flow at the required discharge point. Head pressure will vary with the fluids you are pumping. For example, we have bought a pump that can provide 150 feet of head (45.72m). Then we use it to pump water, the pressure will be around 54.25 psi (4.485 bar). clara baldwin
