Zenit DG Steel 37 0.37kW High Performing Compact 304 Stainless Steel Drainage Pump (Max 150LPM/140kPa)

The Zenit DG Steel 37 is a robust, compact vortex impeller drainage pump made entirely of high-grade AISI 304 stainless steel, purpose-built for handling dirty water and solids-laden stormwater in civil and light industrial applications. Delivering a maximum flow rate of 180 litres per minute and a total head of 8.7 metres, this unit provides reliable performance for stormwater dewatering, sewerage plants, car washes, livestock farms, and hydro-sanitary systems.

Its set-back vortex impeller design ensures a large free passage for suspended solids — up to 25 mm — making it perfect for demanding dirty water tasks where blockages are not an option. Rugged yet lightweight, the DG Steel 37 is protected by a multi-stage mechanical seal system and an integrated oil chamber for extended seal life.
