GR Impeller with grinder system

The GR family consists of electric pumps with immersed multi-channel impeller with a grinding system on the intake. The intended use varies depending on whether 2 or 4 pole motors are used; in the former case, applications are in the livestock farming and food industries where sewage is present. In the second case, applications are mainly in agriculture and livestock farming, with particularly heavily soiled liquids.

Power from 0.74 to 7.2 kW (2 poles)

The GR impeller, designed to provide high heads and high efficiency, is applied to motors with power up to 7.2 kW, for use in the livestock farming, food and residential sectors and wherever grinding of the pumped liquid is required. The diffuser plate incorporates the Anti Clogging System (ACS), consisting of grooves in the plate to facilitate the ejection of ground solids, which ensures that the pump will not become fouled and restarts quickly even with low power ratings.

Power from 3.0 to 4.0 kW (4 poles)

The special hydraulic unit used with 4-pole motors from 2.2 to 3.0 kW 4 comprises a grinding system consisting of a rugged "S"-shaped impeller operating snug against the diffuser plate, with toothed intake orifice. Both the impeller and the diffuser plate are in EN-GJS-600-3 cast iron, heat treated for greater surface hardness. This system is recommended in agriculture, livestock farming and civil applications for liquids with particularly high contents of solids suitable for grinding.
