Just like garden pumps, booster pumps – also known as boosters or pressure-boosting pumps – are self-priming. The pump is commonly used to boost water pressure in pipes, irrigate gardens and lawns, and supply water to toilets, sinks, and washing machines.
The main differences between a booster and a garden pump are:
- Fitted with a tank
- Switches on and off automatically
If the pump has a tank, the initial water supply comes from the tank, preventing the pump from activating for small water demands. Additionally, the tank reduces water hammer, absorbing the “blows” in the pipes caused by sudden changes in water flow when a tap is opened or closed.
A booster pump is self-priming, which means that it draws water from the source and then applies high pressure to use it mainly for irrigation purposes. Water cannot be drawn from a depth greater than eight meters, but it can be pulled horizontally over longer distances.
When to use a booster pump?
If you want to irrigate your garden, a booster pump will be most suitable for you: for example, in combination with a hand-held sprayer. The pump will switch off as soon as you release the handle. Of course, you can also connect impellers or sprinklers to it. If you use rainwater in your home, for example for a toilet or washing machine, a booster pump is most suitable because it automatically supplies relatively small amounts of water. The pump will also need to switch on and off automatically for these appliances.
Which booster pump?
For irrigation, you can make use of a conventional booster pump such as the DAB Aquajet or the Tallas D-BOOST. If you live near a canal, river, or have a clean-water well, consider an underwater booster like the DAB Divertron or Tallas D-ESUB. These are easy to install and ideal for using rainwater in the home for toilets or washing machines. For boosting indoor water pressure, such as in a shower, the booster should be installed indoors. A fully controllable, compact pump that is also quiet and powerful is not a luxury. But if that is what you want, you can opt for a DAB e.sybox (Mini) or a Tallas D-ECONCEPT.
