CR Series

The basic CR Series, which can be applied in almost any industrial solution, is already in itself the broadest range available. Through our modular approach, we have made it even broader.

The basic CR Series is available in four different materials: cast iron, two grades of stainless steel and all-titanium. There are eleven flow sizes, capable of producing up to almost 50 bar of pressure, and with a variety of shaft seals, rubber materials and supply voltages.

Pump parts which are typically vulnerable to difficult liquids or particularly demanding operating conditions can be optimised for their purpose and designed for specific requirements.
