WOMA 2503 High Pressure Plunger Pump

The ultra high-pressure pumps of the 03-series with operating pressures up to 250 bar and flow rate up to approx. 400 l/min, are the specialist for descaling as well as for cleaning of sewers and pipes. In addition to the corrosion-resistant stainless steel version, WOMA also provides a reasonably-priced pump-head variant in grey cast iron. The seal system of this plunger pump is very easy to maintain due to fewer wearing parts. The ceramic plungers used are highly resistant to acid and alkaline liquids. An alternative available is the pump with coated steel plungers, which enhances wearing resistance and resistance to temperature shocks. The 03-series impresses with a good price/performance ratio due to long service lives – even in rough everyday work. A special feature of the 03-series is a second shaft end which allows another pump to be connected and can double the performance if required. All gearboxes of WOMA pumps have an integral oil cooling system. Additionally, all WOMA pumps are certified according to Atex (ExII2GDT5).
