Pumps head
WebHead. This term is an important energy concept (DIN EN ISO 17769-1) in centrifugal pump engineering. A distinction must be made between the pump head and the system head. … WebPump Shut-off head. The shut-off head is one of the most important parameters in the pump. It is defined as the head with respect to zero volumetric flow rate. Pump Static head. Static head means the height difference between the elevation of the source of liquid and the elevation of the discharge liquid.

WebGenerally, pump head is one of the parameters of interest when dealing with forced flow systems. Specifically, it measures the maximum height that a pump can take a fluid against gravity and provides a way to rank pump capacity. There is a misconception that head and pressure are the same due to their directly proportional relationship. WebMar 23, 2024 · We have just accomplished 100 feet of water column, or 100 feet of head. The obstacle is gravity. A pump having a higher head rating can create a higher water column. A higher head AND flow rating means more water, higher. For the purposes of this brief lesson, we will talk about closed-loop flow as it relates to hydronic heating …
