## Beschreibung

## Shock absorber package for automatic submersible pumps 1" (set of expansion tank and T-piece 1 1/4").

The impact damper is suitable for damping pressure surges and for compensating small leakages

It is installed directly on the pump, in the permanent pressure area or directly in the tank,

as the tank is submersible.

### Pedrollo 1SF stainless steel shock absorber (AD) 1l connection 1/2" male

This shock absorber protects the life of your pump!

For pumps with integrated electronic control, the pump will start or stop

the pump starts or stops automatically when a tapping point is opened or closed.

This happens both activation of a solenoid valve by the irrigation controller

as well as by manual water withdrawal from a water socket.

For well pumps, this mechanism can also be achieved by a press control.

To ensure proper operation and avoid frequent restarts, and thus save more energy

the 1 SF tank (or a similar tank with a minimum volume of 1 liter) should be installed with an inlet pressure of

installed with an upstream pressure of 1.2 bar. This avoids frequent pump starts and prolongs the life of your pump.

The dimensions of the expansion tank should be suitable for the pump and the water intake volume.
