Systems for a continuous provisioning generally contain one or several vacuum pumps mounted on a vessel. This includes in the scope of delivery, in addition to connection hoses, also pressure switches, filters, vacuum meters and non-return flaps or valves.

   

PumpstandThe vacuum pumps to be used can be oil-free (VT 4.16 – VTLF 2.250) s well as oil-lubricated (U 4.20 – U 4.400) units. This makes it possible to achieve a vacuum of 90 % or otherwise 99.5 %. Side-channel vacuum pumps can also be employed for a lesser vacuum. Vessels are available in the sizes 90, 250, 500, 1000 and 1500 litre in horizontal versions. Upon request, they can be hot-dip galvanised inside and out.

 

For the automatic regulation of the vacuum level, the systems, which may also consist of a different number of vacuum pumps, can additionally be equipped with a control cabinet. It includes a transformer for power supply of the pressure switch, time relay, On-switch, main switch, operation and fault indicator as well as operating hours counter. 

 

  All systems have been designed so flexibly that they can be equipped with additional accessories uch as separators, ball valves, and so forth without a problem.

 

Beyond even larger oil-lubricated vacuum pumps, 2000 litre vessels can be used with centralised systems. In this case, pumps and vessel are set up separately.

If vacuum provisioning has already been arranged for or is not required, the pumps may also be consolidated in a space-saving rack system. For instance, a medicine rack can be equipped with 3 oil-free vacuum pumps of the VTLF series (or KVT), secretion separators and control cabinet..
