Product Overview
Sewage and blackwater containing fibres or filaments require efficient grinding and pumping systems that maintain performance without clogging. The Zenit GRG 300/2/G50H COET5 is a 2.2 kW submersible grinder pump with ATEX Zone 1 certification, featuring a high-efficiency grinder system with a high-speed rotary knife that slices particles before they reach the impeller. The unit is suitable for civil, residential, professional, and industrial applications including underground carparks and livestock farms.
Maximum head reaches 29.9 metres with a maximum flow of 324 L/Min, driven by a 415V three-phase motor drawing 4.6 Amps. The 2.2 kW motor uses direct starting with 28.2 Amps starting current and produces 7.3 Nm of rated torque. These performance characteristics suit medium-head applications requiring effective solids grinding and pumping.
Hydraulic design incorporates an open channel impeller with grinder system, with the impeller manufactured from Cast Iron EN-GJL 250. The grinder mechanism uses a chromium steel cutter and cutting disk (X102 CrMo17 KU) that process all solids and fibrous materials. Free passage is 0 mm as all solids are reduced by the grinding system before pumping. Hydraulic efficiency is rated at 49.4%.
Construction features a Cast Iron EN-GJL 250 casing with bi-epoxy 200 ?m sea water resistant coating. The shaft is stainless steel AISI 431, and sealing uses two mechanical seals in silicon carbide (2SiC). Motor protection includes Class H insulation, IP68 rating, thermal protection, and a leakage sensor. Cable length is 10 metres with 4G1,5+3x1 configuration, and the unit weighs 43.2 kg. A ZENS9024.006 Ring Stand is required for free-standing operation.
