GRG shredders ready for high fibre content

摘要

Zenit's next-generation GRG models are shredding-pumps with motors from 1.1 to 7.5 kW, cast iron construction and a double mechanical seal in the oil chamber. The pumps are for domestic and residential settings and in small civil or industrial plants. In civil and domestic sewage lifting systems, wastewater which has high solids and fibre content makes working conditions particularly critical for the installed submersible pumps. The optimal choice is a shredder which combines compact dimensions with high reliability.
