Area of use

The BELKI Smart Unit is used to separate particles and tramp oil from process fluids - primarily cooling lubricants. It is a mobile unit that can be easily moved between the individual machine tools. Due to its slim design and the low demands on the electrical supply, this unit is suitable for almost any metal working work shop.


The process fluid is skimmed off by one of the skimming devices of the BELKI Smart Unit, or with a suction device to filter the bottom of the machine sump. The particles are separated via the deep bed filter, the tramp oil is separated via the integrated oil separator. Even the finest ferritic particles can be retained by the optional magnetic filter. The separated oil is stored in an inner tank, the particle load is fed into a sludge box and the used filter paper is automatically wound up. The cleaned emulsion is returned to the machine sump.


  • Oil separation and filtration in one operation
  • Highly mobile and easily adjustable for optimum results
  • Power connection via 230 V / 50 Hz connection
  • Robust pump for chips up to approx. 4 mm
  • An optional magnetic filter ensures that even very fine particles can be filtered out of the emulsion.
  • A very effective oil separator increases the lifetime of the emulsion

Connection and installation of the BELKI Smart Unit

The BELKI Smart Unit is started up pushing two switches. One switch starts the self-priming pump, the other switch activates the integrated deep bed filter. The deep bed filter must be active for the pump to run. The hoses are connected using the standard Camlock coupling. This is quick, uncomplicated and self-explanatory. For low tanks, a bottom suction device is installed, which also fits into small access openings. A standard 230 V socket is sufficient for the electrical supply. The scope of delivery includes two hoses 3/4'' and one hose 1 1/4''. All hoses are 3 m long.

Suitable accessories for the BELKI Smart Unit are surface skimmers and bottom suction devices, various brackets and connection as well as a magnetic filter. The available variants are listed here.
