Product description

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.

Depending on intended use;

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

What Are the Specifications of the Wilo Jet HWJ202 Multistage Centrifugal Pump, 35 m, 4.5 m³/h?

This compact centrifugal pump system with a horizontal suction inlet and vertical discharge outlet consists of the following:

A self-priming, single-stage jet pump with a pump shaft running through the motor and a mechanical seal independent of the direction of rotation.
A directly flanged single-phase and three-phase motor with an integrated thermal motor protection switch and, in the single-phase model, a capacitor.
A pump control unit with a mounting set comprising a diaphragm pressure tank, a pressure switch, and a pressure gauge (0–6 bar). All fluid-contacting parts are corrosion-resistant.
The pump system comes pre-assembled and ready to connect, with 2 m cables and electrical plugs already wired.
Ideal for garden and hobby use. The three-phase model is connected via the terminal box.
