They can be used either as vacuum pump or as a small compressor, and they are able to deliver 100% oil-free compressed air, at a maximum pressure of 1 bar. They consist of: - A small single-phase electric motor, with protection class IP 00 (assembling execution), aircooled. - A pump body made of plastic material resistant to corrosion, complete with fittings at both suction and blowing ports. - A diaphragm, integral to a connection rod, made of special materials, resistant to wear and corrosion. - A connection rod with builtin long-life bearing, driven by a balanced eccentric system splined to the motor shaft. - Aluminium bracket to hold the pump, available in two versions. The diaphragm small vacuum pumps are very noiseless (<50dBA), have low vibrations and can be installed in every position. Without lubrication, no maintenance is needed. Their compact size and light weight makes them particularly suitable for installation on portable equipment. They are suitable for intermittent and not heavy use only. 7.01

2 Small vacuum pumps They are very small vacuum pumps with rotating vanes that can also be used as a small compressor for pressures up to 2 bar. They are made up of a singlephase induction electric motor with capacitor (upon request they can be supplied with D.C. motor), a self-lubricating stator in sintered metal, a rotor in white metal splined to the motor shaft and grooved for housing the hardened steel vanes and a silencer on the exhaust. The operating principle is the same as the vacuum pumps with rotating vanes of the bigger series. They are noiseless, completely lubrication-free and they do not need any maintenance. Due to their very small size and weight, they are particularly suitable for the installation on portable equipment. They are suitable for intermittent and not heavy use. Model.

3 Vacuum pumps VTL 2 and 4 These small vacuum pumps have a suction capacity of 2 and 4 cum/h. They are wick oiled with loop lubrication system and because the rotor is overhanging splined to the motor shaft, they are of small dimensions. Motor and pump are cooled by the motor fan (surface cooling). These pumps are provided with a small tank placed on the same axis of the pump, containing the lubricating oil as well as a separation filter that prevents oil mists and reduces noise as well. It is recommended to install a check valve and a suitable filter on the pump suction inlet. Pumps VTL 2 and 4 can also be supplied with single-phase electric motor.

They consist of: - A small tank in welded steel plate having a perfect vacuum seal. - A vacuum pump with rotating vanes, having a small capacity, either dry running or lubricated. - A small vacuum switch for the maximum vacuum degree adjustment. - A vacuum gauge for direct reading of the vacuum degree. - A switchgear contained in a special protected box. - A manual valve for the vacuum interception. The holding of the vacuum degree in the tank, preset by means of the small vacuum switch, is fully automatic. The small pumpsets are suitable to equip small stationary or mobile working units (they can also be supplied with motors at 12 and 24 V/d.c.), which require vacuum, such as: - Trolleys with cups for fixing and moving glasses and crystals. - Stirrup systems with vacuum for the ski maintenance, to drill or pantograph marbles, to polish pewter, copper or silver objects etc. - Tackles with cups for lifting television sets, various electrical household appliances, to fix glasses into window and door frames, to feed plates into presses etc. 7.21

21 Horizontal pumpsets Currently produced in various capacities and ranges, they are made up of: - A tank in welded steel plate having a perfect vacuum seal. - A vacuum pump to be selected according to the required suction capacity and vacuum degree. - A vacuum switch for the adjustment of the operative vacuum degree range. - A vacuum gauge for direct reading of the vacuum degree in the tank. - A switchgear, contained in a proper tight metal box, with magnetic starter with overload and undervoltage protection, fuse carrier with fuses to protect the plant, transformer for the supply of the low voltage auxiliaries, mains switch with pilot lamp, a switch for the continuous or automatic operation of the pumpset and an hour counter (starting from the 100 litres tank). - A manual valve for the vacuum interception. - A drain cock for the condensate removal. They are normally used for moving particularly heavy or valuable loads, because in the event of electric current failure, they allow the cups to hold the load for a certain time after failure (variable according to the tank capacity). They are also recommended in multi-point applications, to centralize vacuum. In both cases the use of the pumpset is particularly profitable under the point of view of the energy consumption, because the pump starts working only when vacuum is required by the machine Art.

They are basically made up of: - A horizontal tank in welded steel plate having a perfect vacuum seal. - Two vacuum pumps to be selected according to the required suction capacity and vacuum degree. - Three vacuum switches, two of which to adjust the vacuum degree within which each pump must work and one to fix the minimum safety value to be assured in the system, under which the alarm device must trip. - A manual interception valve to cut out or to connect the pumpset to the user system. - A drain cock for the condensate removal. - A switchgear contained in a proper tight metal box, consisting in magnetic starters with overload and undervoltage protection, protection fuses, transformer for the supply of the low voltage auxiliary controls, automatic time reverser, terminal blocks for the electric connection and, on the panel, main switch with door opener lock, warning lights for the mains and for the pumps operation, commutators for selecting manual or automatic running, alarm device with sound and light signal, push buttons for the alarm test and hour counter. The safety pumpset with this layout normally provides the operation of one pump and the subsequent connection of the second one in case of higher consumptions and when, for whatever reason, the vacuum degree of the plant goes under the fixed value. The automatic time reverser, installed in the switchboard, exactly alternates the priority starting of the pumps, in order that they are submitted to the same mechanical wear. The warning device on the switchboard and the remote one start up when the vacuum degree of the plant goes under the minimum safety value fixed. 7.23

23 Vertical pumpsets Currently produced in various capacities and ranges, they are made up of: - A vertical tank in welded steel plate having a perfect vacuum seal. - A vacuum pump to be selected according to the required suction capacity and vacuum degree. - A vacuum switch for the adjustment of the operative vacuum degree range. - A vacuum gauge for direct reading of the vacuum degree in the tank. - A switchgear, contained in a proper tight metal box consisting in: low voltage transformer for the supply of the auxiliary controls, protection fuses, remote control switch with thermal cutout, terminal block; on the control panel there are the main safety switch with door opener lock, a line warning light, a commutator for selecting manual or automatic pump running and an hour counter to show the real pump working time. - A manual valve for the vacuum interception. - A manual valve to drain condensate. Pumpsets are mostly used for the interlocking of several machines with vacuum, and for safety reasons, for moving particularly heavy or valuable loads, because in the event of electric current failure, they allow the cups to hold the load for a certain time after failure, in proportion to the tank capacity. In both cases, the use of the pumpset is particularly profitable under the point of view of the energy consumption, because the pump starts working only to restore vacuum in the tank, within the fixed values and its operations depends exclusively on the real sucked air quantity at the use Art.
