Product details
Catalog selections are divided between 1,450 and 2,900 r/min. The model code provides dimensional information: in IH80-65-160A, 80 identifies the inlet diameter in millimetres, 65 the outlet diameter and 160 the nominal impeller diameter; the A suffix denotes an impeller trim. A trimmed variant should not automatically receive the untrimmed model’s curve.
The performance table includes the IH80-65-160 selection at 50 m³/h and 32 m head with an 11 kW two-pole motor. This individual row is a more specific selection reference than the series-wide extremes. Actual absorbed power remains dependent on the liquid and the operating point.
The manufacturer lists stainless material alternatives within the range. A material option is not a universal corrosion-resistance statement: the fluid composition, concentration and temperature must be matched to the selected wetted parts and seal. The adjacent product families on the catalog page have separate parameters and are not included in the IH envelope here.
