The ULN series is a horizontal pump manufactured by SIHI Group. It is a single-stage volume casing pump with dimensions and nominal outputs that conform to EN 733/DIN 24255 standards.

The back pull out construction demounts the complete bearing unit to the drive side, without detaching the pump casing out of the piping. The pumps are used for applications that need to suck in and handle pure resp. turbid, and non-aggressive liquids that contain solids. It is then suitable for drinking water supply in different industries.

ULN has a maximum flow rate of 300m³/h, and a maximum speed of 3,000 rpm. It has a maximum operating temperature of 120°C, while the maximum casing pressure is 16/10 bar. The head has a maximum size of 95 m, and can be suctioned in cool water up to 5 m.
