Pumps are a vital part of successful manufacturing and we strive to match the right pump with the right application to ensure trouble-free operation and high standards of hygiene. Gerhard Unger partners with Alfa Laval, one of the world’s leading pump specialists, to offer centrifugal pumps, liquid ring pumps and rotary lobe pumps.

We recommend pumps using state of the art Computational Fluid Dynamics (CFD). This is a type of flow technology that models how a pump will handle a liquid, allowing us to identify the perfect match that is fully optimised for efficiency. You can rest assured knowing that each Gerhard Unger pump offers superior performance thanks to its design and sturdy construction.

All of this comes together to offer you ease of maintenance, retrofitting and seal conversion.
