Product details
The IHF family uses fluoroplastic wetted construction, with FEP and PVDF alternatives described in the catalog. These alternatives require selection for the actual chemical, concentration and temperature. A general acid or alkali application label does not establish compatibility with every process mixture.
The selected 2,900 r/min row reports 2.83 kW shaft power, 38% efficiency and 2 m required NPSH. Shaft power is distinct from the 4 kW motor rating. Efficiency and NPSH belong to the listed catalog duty; neither is a guarantee across the complete operating curve.
The table also contains a lower-speed version under the same size designation. This page retains the 2,900 r/min selection so its flow, head and motor values remain together. The official image shows an IHF coupled assembly; installation dimensions, impeller trim, lining grade and the supplied seal arrangement must be confirmed for the ordered unit.
