Automatic air system

Filling of the air cushion of pressure vessels for installation of centrifugal pumps

Aerator for centrifugal pumps for automatic filling 

of the air cushion in galvanised pressure vessels.

Max. operating pressure: 10 bar

 

Available in two dimensions:

  • Pressure vessels to 500 l - connection: ½" x ½"

  • Pressure vessels to 2.000 l - connection: ½" x ¾"

A - The centrifugal pump stops. The vessel is full of water.

B - When the centrifugal pump starts, negative pressure is generated and the water is sucked out of the vessel. Air enters through the aerator valve.

C - The aerator fills with air until the ball closes the hole connecting it to the pump.

D - When the centrifugal pump stops, the air in the aerator enters in the pressure vessel due to the principle of communicating vessels and, being lighter, flows upwards into the pressure vessel.

Sniff valve - water outlet valve - level switch

Filling of the air cushion of pressure vessels for installation of submersible pumps

The sniff valve is located below the check valve in the area above the water level

(must be able to draw in air) is installed in the riser pipe and is used for filling

of the air cushion in galvanised pressure vessels when operating a submersible pump.

 

The submersible pump must not have a ckech valve incorporated,

otherwise, this must be removed or a water outlet valve must be installed in the

water-bearing layer above the pump.

 

The level switch is installed in the pressure vessel and releases any excess air if necessary.

 

When the submersible pump switches off, the water flows back into the well either through

the submersible pump or through the water outlet valve. The sniffer valve allows 

air to fill the pipe. The air is forced into the pressure tank the next time the pump is started.
