The Key Elements of Great Heating
A booster pump is just a pump, with a bladder tank or without, that allows you to raise domestic water pressure or maintain it in the pipes during times of heavy demand. Pool owners will find it smart to operate at relatively high pressure because automatic cleaners and other robots are do better at removing encrusted dirt.
You may want to get a swimming pool booster pump for your system. But what factors are considered in determining booster pump power, flow and pressure?
Pressure refers to the force of the water in B (bars) at discharge point, depending on pump pipe cross-section. Manufacturers can also indicate pressure in terms of CMW (column metres of water).
Pressure is flow’s best friend. This is a fundamental law of hydraulics: for a particular flow, a bigger-section pipe will produce less pressure compared to a smaller-section.
The unit used to express discharge height is CMW. It’s a vital criterion because you have to make sure that the pumped water gets to the intended discharge point. Surface pump manufacturing companies often report a discharge height (the difference in level between pump and discharge point) or a TMH (the total manometric height expressed in metres).
The central technical property of water systems is none other than flow. The flow rate refers to how much water is pumped as a function of time.
When choosing a pump, keep in mind though that flow rate will vary on the basis of suction depth and the discharge height. For a particular diameter of pump pipe, the same pump will create less flow as the height difference goes up.
On the other hand, the shorter the height between your suction and discharge points , the greater the flow rate. 250m3/h for each additional person. If it’s for watering a garden, 1m3/h should be adequate for 400m? and 3.
Around 2 to 3 B is considered the ‘comfortable’ domestic water pressure range, depending on how far the water supply point (water reservoir or tower) is located. Hence, the most remote, “end of the line” properties may experience low pressure and find a booster helpful.
If you suck water from a well, be aware of the suction depth along with the type of water you’re pulling up. Pay attention to discharge height too i.e. the height of the surface pump relative to where the water is distributed – for example, if you plan to water a garden that lies high above the well. Those who use an automatic watering system should take time to determine their required flow. Obviously, you will need more water the more watering points you have.
