The ARP-series has operating pressures up to 400 bar and nominal flow rates up to approx. 1,680 l/min.

A special feature of this series is its high reliability even when conveying media contaminated with granular or fibrous solids up to a solids concentration of 3,000 mg/l and a grain size of up to 300 μm. This series is particularly suitable for sewer and pipe cleaning, as well as descaling in the steel industry.

The pump head of the ARP series up to gear size 250 can be ordered as a cost-effective cast variant or as a robust NIRO variant. On request, the use of super duplex steels can also be tested for maximum resistance (deviation of technical data may apply).

On request, an ATEX version is also available.
