    The filter assembly consists of a filter block with an integrated electric motor, a gear pump, a filter housing and a filter element. With its double-bearing drive shaft design, the internal-gear pump is extremely quiet and virtually vibration-free, with excellent suction capacity and sophisticated mechanical- and volumetric efficiencies.

    The filter aggregate is fitted with a 2-step filter element with MAHLE Premium Select (PS) filter media. The first filtration stage consists a 10 µm fine filter and the second stage a 50 µm safety filter. Other degrees of filtration are available on request. All retention rates are according to ISO 16889.

    This filter assembly with MAHLE PS filter elements achieves an excellent cleanliness class up to 17/15/11 and even better according ISO 4406/1999. For monitoring the filter element, optional a differential pressure indicator is available. For customized requirements we offer a wide range of MAHLE differential pressure indicators with 1 or 2 setting-points, LED indicators, various types of contacts, analog outputs, temperature suppression and connecting plugs.

    The pump units are suitable for all mineral-oil-based hydraulic oils and lubricating oils.

    The standard scope of supply includes the complete unit with electric motor, internal-gear pump, filter housing and filter element.

    Units are available for prompt delivery.
