Zenit DRG 750 5.50kW 415v Cast Iron 2 Pole Drainage Pump (Max 2470LPM/250kPa)

The Zenit DRG 750 is the powerhouse of the Zenit Grey Series, engineered to handle the most demanding drainage and wastewater challenges in industrial and civil environments. Designed with a multi-channel open impeller and robust cast iron hydraulics, this ATEX-certified unit delivers an outstanding maximum flow of 2470 litres per minute and a head of up to 25 metres.

Ideal for stormwater pits, wastewater treatment plants, industrial process water, and civil lift stations, the DRG 750 is built for continuous duty where high flow capacity and reliable solids handling are essential. ATEX Ex d flameproof certification makes it safe for installation in potentially explosive atmospheres.
