Zenit DRG 1000 7.50kW 415v Cast Iron 2 Pole Drainage Pump (Max 2700LPM/350kPa)

The Zenit DRG 1000 is the largest and most powerful model in the Zenit Grey Series, purpose-built for high-capacity, heavy-duty drainage and wastewater transfer in industrial and civil installations. Delivering a maximum flow of 2700 litres per minute and a total head of up to 35 metres, this pump handles tough conditions with reliable solids handling and continuous-duty performance.

Featuring a multi-channel open impeller and robust ATEX-certified cast iron construction, the DRG 1000 is ideal for lifting stormwater, process water, sewage, and liquids with suspended solids in demanding applications. ATEX Ex d flameproof certification ensures safe operation in potentially explosive atmospheres.

FEATURES

• ATEX Certified Ex d — Flameproof for safe use in explosive atmospheres (II 2G Ex db IIB T4 Gb, Ex h IIB T4 Gb)
• Massive Flow & High Head — Up to 2700 L/min (45 L/s) and 35 m max head
• Multi-Channel Open Impeller — Efficiently passes solids up to 40 mm
• Rugged Cast Iron Construction (EN-GJL 250) — Impeller and casing designed for harsh wastewater conditions
• Stainless Steel Shaft (AISI 431) — Corrosion-resistant, strong, and tapered coupling to the impeller
• Dual Silicon Carbide Mechanical Seals (2SiC) — Isolated in a large oil chamber with leakage sensor for protection
• Leakage Detection System — Monitors the oil chamber to protect mechanical seals and motor
• Universal GAS Thread Cable Gland — Accepts protective sheathing for cable safety
