The high-pressure plunger pumps of the 2-series, with operating pressures up to 750 bar and flow rates up to approx. 224 l/min, are ideal for the cleaning of pipes and tube bundles, vessels, and containers. Variant V of the 2-series has been specially developed for applications with elevated inlet pressure.

The sealing system of this plunger pump is particularly service-friendly due to fewer wearing parts and easy maintenance. The ceramic plungers used are highly resistant to acidic and basic fluids. Alternatively, the pump is available with coated steel plungers for increased wear resistance and resistance to thermal shocks. The sealing water system prevents leakage, enables higher durability of the high-pressure seals, and counteracts the ingress of air. As a result, the 2-series offers a high price-performance ratio even in rough working conditions.
