Zenit DRG 300 2.20kW 415v Cast Iron 4 Pole Drainage Pump (Max 1940LPM/120kPa)

The Zenit DRG 300 is a robust, ATEX-certified submersible drainage pump from the Zenit Grey Series, designed for medium head, high-flow drainage and wastewater applications in civil and industrial installations. With a 4-pole motor, the DRG 300 delivers powerful yet efficient performance at lower speeds, moving up to 1940 litres per minute with a total head of up to 12 metres.

Its heavy-duty multi-channel open impeller easily passes solids, making it ideal for pumping clear or slightly soiled water with suspended solids. The pump’s rugged cast iron construction, integrated leakage detection system, and large oil chamber ensure safe, reliable operation — even in areas requiring ATEX Ex d flameproof certification.
