Overview

This horizontal pump with double suction impeller and a between bearing design is perfect for pipeline applications as it is constructed under the API standards. The additional diffuser ensures a high efficiency. By changing the impeller and diffuser the BEP can be shifted in a wide range to achieve low power consumption and a long lifetime of the pump. It can also be used for other applications.
