Vacuum pumpsets are independent units, suitable for every application of creating and managing vacuum. They are divided in mini, horizontal and vertical pumpsets, depending on the application and their setting on the site. However, their basic discrimination depends on the way of creating the vacuum, by a pump or a vacuum generator.

Pumpsets with vacuum pump

These pumpsets are built with various capacities and they are composed of:

• A welded sheet steel tank with perfect vacuum seal.
• A rotating vane vacuum pump to be selected according to the required suction capacity and vacuum degree.
• A vacuum switch for adjusting the vacuum level within which to operate.
• A vacuum gauge for a direct reading of the vacuum level in the tank.
• A switchgear enclosed in a special plastic casing for tanks from 25 to 50 litres and in a watertight metal casing for tanks of 100 litres upwards.
• A manual valve for vacuum interception.
• A cock for condensation drainage.

The vacuum level, preset via the vacuum switch is automatically maintained in the tank. The pump operation can be either continuous or automatic.

Pumpsets are normally used for handling particularly heavy or valuable objects since, in case of electricity failure, they allow the vacuum cups to maintain the grip for a certain amount of time, according to the tank capacity. They are recommended for multi-point applications, to centralise vacuum. They offer many advantages in energy consumption, since the pump operates only when required by the machine.

Pneumatic pumpsets are fed exclusively by compressed air and they are composed of:

• A welded sheet steel tank.
• A compressed air-operated vacuum generator, equipped with an energy-saving device.
• A vacuum gauge for a direct reading of the vacuum level.
• A manual valve for vacuum interception.
• A suction filter with a paper cartridge.
• A pressure adjuster equipped with filter.
• A sleeve valve for compressed air interception.
• A cock for condensation drainage from the tank.

Pneumatic pumpsets with vacuum generator

The vacuum level in the tank, previously set with the vacuum switch, is automatically maintained.

Pneumatic pumpsets are normally used for handling particularly heavy or valuable objects since, in case of a sudden power supply failure, they allow the vacuum cups to maintain the grip for a certain amount of time (which varies according to the tank capacity). They are recommended for connecting several applications to centralise vacuum. In any case, the use of the pumpset offers a great advantage under an energy-saving point of view, since the generator operates only when vacuum is required by the application.

Pneumatic pumpsets require no electricity, only compressed air at 4-6 bar pressure. For this reason they are recommended in hazardous environments where an ignition source would be dangerous.
