WebFor a common application - where the pump lifts a fluid from an open tank at one level to an other, the energy or head at the surface of the tank is the same as the energy or head before the pump impeller and can be expressed as: h 0 = h s + h l (4) where. h 0 = head at surface (m, in) h s = head before the impeller (m, in) WebMax Head refers to a pump’s capability to push water upwards (also known as ‘vertical lift’). So for example, a pump which states ‘Max Head: 7m’ means the pump will be able to push water flow up to 7 metres high from the water surface. What is often overlooked is that at 7 metres lift, the pump will deliver zero flow!

‘Head’ and ‘pressure’ in pumps Water Technology

WebHead is the height to which a pump can raise water straight up. Water creates pressure or resistance, at predictable rates, so we can calculate head as the differential pressure that a pump has to overcome in order to raise the water. Common units are feet of head and pounds per square inch. WebLift definition, to move or bring (something) upward from the ground or other support to a higher position; hoist. See more. WebSuction head = h s = p s / ρg + v s2 / 2 g. From the definition of vapor pressure head, Vapor pressure head = h v = p v / ρg. In the simplest language, we can say, NPSH = Pressure head at the inlet or suction – vapor pressure head. Let’s see the formula or equation of NPSH, NPSH = hs – hv. lydia herrera mata
