Zenit DDG400 Cast Iron 4 Pole Industrial Vortex Drainage Pump (Max 1660LPM/110kPa)

The Zenit DDG 400 is a rugged, high-capacity 4-pole submersible vortex drainage pump, purpose-built for industrial and municipal wastewater applications. With a maximum flow of 1660 LPM and a head of 11 metres, this unit is ideal for lifting stormwater, sewage, and dirty liquids containing suspended solids in hazardous or demanding environments.

Constructed entirely from EN-GJL 250 cast iron and equipped with a set-back vortex impeller, the DDG 400 ensures excellent solids handling, clog-free operation, and long-term durability. Fully ATEX certified (Ex d), it meets safety requirements for installations in explosive atmospheres.

FEATURES

• ATEX Certified Ex d — Safe for use in hazardous areas (II 2G Ex db IIB T4 Gb, Ex h IIB T4 Gb)
• Set-Back Vortex Impeller — Offers full free passage up to 80 mm for solids-laden liquids
• Robust Cast Iron Construction — Casing and impeller built from EN-GJL 250 cast iron
• Efficient 4-Pole Motor — Low speed for smooth, continuous duty operation
• Silicon Carbide Mechanical Seals (2SiC) — Dual seal system in an oil chamber with leakage detection sensor
• Universal Cable Gland (GAS Thread) — Accepts protective sheathing to safeguard power cable in turbulent or corrosive fluids
• Wet Installation — Requires base plate (ZENS9024.007) for free-standing installation
• Factory Pressure Tested — Guarantees seal and gasket integrity
