Zenit DG Blue 40 Series 0.30kW 240v Cast Iron Vortex Drainage Pump (Max 270LPM/60kPa)

The Zenit DG Blue 40 is a compact, robust vortex drainage pump designed for reliable handling of dirty water, biological wastewater, and sewage in residential and domestic settings. With a maximum flow rate of 270 litres per minute and a head of 6 metres, this pump easily manages soiled wastewater containing suspended solids up to 40 mm, making it ideal for household pits, small lift stations, garages, and workshops.

Built with a durable cast iron hydraulic section and a recessed vortex impeller, the DG Blue 40 guarantees excellent solids expulsion while minimising the risk of clogging. Its IECEx Zone 2 approval ensures safe use in potentially explosive areas where flammable vapours or gases may be present.
