Filtering hydraulic oil with the filter-pump unit<\/h1>

The filter-pump unit is a mobile oil maintenance unit for filtration during the filling of systems as well as for the pumping of hydraulic and lubricating media.<\/p>

It is suitable for filtering hydraulic oil<\/a>s and pumping in hydraulic and lubricating oil systems. Further information on the topic of fine filtration of hydraulic oil<\/a>. <\/p>

Advantages of filtering hydraulic oil with the filter-pump unit<\/h2>
  • Easy handling and transport<\/li>
  • Simple filter replacement<\/li>
  • Convenient off-line filtration<\/li>
  • Suction of contaminated media<\/li>
  • Filling and filtering of fresh oils<\/li>
  • Cleaning to specific NAS\/DIN ISO classes<\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
