60 Hz PRODUCT RANGE1.4 GR (GRINDER)Grinder pumpsThe GRINDER (GR) family consists of electric pumps with multi-channel open impeller with a grinding system .The intended use varies depending on whether 2 or 4 pole motors are used; in the former case, applications are in the residential sector andlivestock farming where sewage is present. In the second case, applications are mainly in agriculture and livestock farming, with particularlyheavily soiled liquids.0.74 ÷ 4.1 kWThe GR impeller, designed to provide high heads and high efficiency, is appliedto motors with power up to 4.1 kW, for use in the livestock farming, food andresidential sectors and wherever grinding of the pumped liquid is required. Thediffuser plate incorporates the Anti Clogging System (ACS), consisting of groovesin the plate to facilitate the ejection of solids, which ensures that the pump willnot become fouled and restarts quickly even with lower power ratings.H (m)m 3 /hGR BluePROGRS-GREGRNl/mGR BluePROElectromechanical assembly in EN-GJL-25 cast iron. 2 (two) opposing silicon carbide mechanical seals in oil sump, V-ring indirect contact with the liquid.
