RZP20
The new recirculation pump RZP 20 has been designed to complete the series for low Q/H-ranges with low power inputs. Its discharge pipe connection is DN 200. It replaces the RZP 22.
Its polyurethane propeller has got the patented hub helix.
Due to different possible propeller-combinations an adaptation to different duty points is possible.

RZP25-1
Due to the use of high-power motors the new recirculation pump type RZP 25-1 is suitable for bigger heads and capacities than its predecessor, the type RZP 25. It has got a new sealing housing with separate screwed drain plug. To protect the mechanical shaft seal against pollution the patented hub helix is used. Also new polyurethane and steel propellers increase the efficiency. Due to different possible motor-propeller-combinations an adaptation to different duty points is possible.

RZP60-3
The new recirculation pump RZP 60-3 has been designed to complete the series between the types RZP 50-3 and RZP 80-1 for pipelines DN 600. Its weight is low and its efficiency is high. A new pressure pipe connection facilitates the connection and releasing of the pump. Due to different possible motor-gearbox-propeller-combinations an adaptation to different duty points is possible.

Inline
Another variant for the use of recirculation pumps is the inline design where the recirculation pump is installed in the pipeline. This can be the case when there is no installation possibility at the beginning of the pipeline or when a new impulse is to be given to the flow.
