Wilo booster pump options
The Wilo booster pump category includes models for a range of needs, from detached houses to medium-sized apartment buildings. The Jet HWJ series are classic twin-pump booster sets that combine a self-priming multistage pump with an expansion vessel. The Aqua series automatic booster pumps are designed for domestic use with their tank-integrated structure and automatic controls. The Isar BOOST5 is a variable frequency drive (VFD) model that operates quietly and focuses on maintaining constant pressure.
Which model is right for whom?
- Jet HWJ 202, 203, 204: Detached houses, gardens, and buildings with few apartments; head increases with model number.
- Aqua SPG and SPS Mini: Tank-type automatic booster pumps; domestic use up to the number of floors and apartments indicated in the product names.
- Isar BOOST5: Larger buildings requiring quiet operation and constant pressure.
Thanks to their self-priming design, Jet HWJ models can draw water even in systems where the unit is installed above the tank level.
Installation recommendations
Install the booster pump on a flat, solid surface in a location that allows easy maintenance. The suction pipe should be as short and straight as possible, with a foot valve at its end. The pump casing must be filled with water before the pump is started for the first time. On variable frequency drive (VFD) models, the target pressure is set according to the requirement at the top floor of the building.
Frequently asked questions
What is the advantage of a variable frequency drive (VFD) booster pump?
It adjusts the motor speed according to consumption, keeping pressure constant while reducing noise and energy use.
What is the difference between Jet HWJ models?
As the model number increases, the pump's head and flow rate increase. Compare the product specifications and select the model that matches your building's height.
Where can I find other Wilo pumps?
For circulation, submersible, and drainage pumps, you can visit the Wilo brand page.
Are there other brands with similar capacity?
Yes; you can browse the domestic booster pumps category for comparison.
Why does the Wilo booster pump's tank matter?
The tank stores pressurized water, preventing the pump from starting up for brief uses. Checking the tank's air pressure once a year prevents the pump from cycling too frequently.
What is the maximum suction lift?
Self-priming models can draw water in installations above the tank level; however, efficiency decreases as suction lift and suction pipe length increase. Do not exceed the suction limit stated in the product specifications.
