U SERIES FAQ
Selection questions answered from evidence.
Which models are in the U 2.2-5.5 kW 2P range?
The published data groups 65U22.2, 65U23.0, 80U24.0 and 80U25.5 in one product entry, with 65 mm or 80 mm outlets and a 56 mm impeller passage.
Does every model have both catalog frequencies?
No. The current English catalog contains seven records. Three models have 50 Hz and 60 Hz records, while 65U23.0 currently has only 50 Hz.
Why do some outlet cells show a dash?
The current catalog leaves outlet diameter empty in all four 50 Hz records. Published data states 65 mm for 65U22.2 and 65U23.0 and 80 mm for 80U24.0 and 80U25.5, but this page does not overwrite catalog fields.
What installation arrangements are documented?
Published data documents movable soft-pipe installation R, hard-pipe installation Y and auto-coupled installation Z, with separate dimension tables.
Can 308 GPM and 23 m be used as one duty point?
No. They are separate maximum-flow and maximum-head limits. Confirm the operating point against the appropriate 50 Hz or 60 Hz curve.
