UHE-Series; with integrated overflow valve and bypass

Technical selection chart: scaled drawings

Direction of rotation of the pumps

I = indirect – counterclockwise
D = direct – clockwise

The direction of rotation can only be changed in the factory. Therefore please assure that you state the desired direction of rotation as per dimension sheet when ordering. Standard design of the pump for two pipe installation, design for one pipe installation on enquiry!
