Water Pump Head

We will get to that later.

Water pump head. If you have to pump a liquid up 30 feet and your pump doesn t have at least 30 feet of head then there is no chance it will work. The greater the pump head the greater the pressure that the pump can generate. This is important to know especially since your water source and pump will likely be lower than its access points on your property. If you need a pump to develop 30 psi of water pressure then buy a pump that develops 70 feet of head.

Allow me to refine a couple of points. Your pump will need at least 30 ft. The pressure at the bottom of a 40 foot lake or a 40 foot high thin tube would be identical since only height is involved. Most pump applications involve moving fluid to a higher level.

Ok so head is somehow linked to pressure in what way. Hydraulic head or piezometric head is a specific measurement of liquid pressure above a vertical datum. The given head is fluid independent. Or in h2o or metric.

Head loss filters heater chiller skimmer uv etc. The pump head or discharge head of a water pump is a measure of the power of a pump. Select nominal pipe diameter inches using the pull down menu. If you were to attach pipes to your pump and extend them vertically upwards how far can your pump pressurise water against gravity.

Water head pressure is static pressure caused by the weight of water solely due to its height above the measuring point. So it turns out that back in 1965 the pump sales rep was trying to show me the correct pump for my application. Definition of head and pressure headis the height given by the pump to the fluid and it is measured in meters of liquid column m l c or simply indicated in meters m. Connect a tube to the discharge of a pump and measure the water height that the head of the pump.

This statistic is measured in meters or feet and is calculated by placing a tube on a pump s discharge and measuring the maximum height to which it can pump water. Different fluids with different specific gravities are all lifted at the same height. For now let s agree to state that the more pressure the pump delivers the higher the head will be in the figure 2. Enter the number of pipe fittings elbows tees.

Pumps develop differential head or differential pressure. Pump head is about water pressure your pump can handle only vertically. The value may be expressed as pounds per square inch psi or inches of water column pressure in. Head is the height at which a pump can raise water up that s it it s that simple.

Intuitively a pump that exerts more pressure should be able to pump water higher and therefore have a higher head. Plus the friction loss to get the required flow at the discharge point. So the discharge pressure is equal to. Figure 2 the meaning of head.

This means the pump takes suction pressure adds more pressure the design pressure and generates discharge pressure. It is usually measured as a liquid surface elevation expressed in units of length at the entrance or bottom of a piezometer in an aquifer it can be calculated from the depth to water in a piezometric well a specialized water well and given information of the piezometer s elevation. Enter total pumping lift or height feet water is pumped vertically. This basic calculation is widely used to solve many different practical problems involving water and other liquids of known.
