What Is a Booster Pump?

Booster pumps are automatic pumps used to pressurize water where mains pressure is insufficient. They can be used on their own or, in some plumbing systems, together with a water storage tank.

They pressurize mains water in homes, apartments, buildings, villas, and residential complexes, or deliver water from a storage tank to the plumbing system under pressure.

What Are the Applications of Booster Pumps?

    • Booster pump systems are used in homes and gardens, detached houses, and villas, as well as in low- and multi-story buildings, apartment complexes, and large structures such as schools, hospitals, office centers, and shopping malls.
    • They are used to maintain the desired pressure and flow rate at a constant level for comfortable water use. To ensure a long service life and reliable water supply, pressure and flow rate calculations must be carried out carefully based on the installation site.

By intended use, booster pumps are available for:

  • Domestic water supply,
  • Fire-fighting water supply,
  • Irrigation water supply,
  • Process water supply.

What Are the Features of the Pedrollo JSWm 3BH Digital Jet Twin-Pump Booster Set?

These types of twin-pump booster sets are systems used in apartment buildings, villas, schools, hospitals, factories, and housing complexes.

The booster pump automatically activates the moment water consumption begins and automatically stops when water consumption ends.

These are small domestic booster pumps ideal for residential use. With a suction lift capacity of 9 m, they deliver maximum suction even in locations where the water supply is intermittent. They can be used safely in applications requiring high pressure with low power consumption. These long-lasting booster pumps are suitable for buildings of up to 12 floors and 8 apartments, as well as for garden irrigation.

All settings are pre-configured; only the plumbing and electrical connections need to be made. Covered by a 2-year warranty.

The pre-charge gas pressure of the expansion vessel must be checked every 6 months and any pressure loss must be topped up.

In booster sets, the advantage of the expansion vessel is that when a small amount of water is used, the booster pump does not activate — it first uses the water stored in the tank, and only when that is depleted does the pump start. This means the pump will not stop and start with every water use, resulting in a longer service life. In other words, the larger the expansion vessel on your booster set, the more water it stores, meaning the pump will work less hard and last longer.
