Zenit DDG1000 Cast Iron 2 Pole Industrial Vortex Drainage Pump (Max 2910LPM/200kPa)

The Zenit DDG 1000 is the most powerful 2-pole vortex drainage pump in the Zenit Grey Series. Designed for high-volume wastewater and sewage applications, it delivers a massive 2910 LPM (48.5 L/s) at a maximum head of 20 metres. Built entirely from heavy-duty cast iron EN-GJL 250, the DDG 1000 is ideal for pumping heavily contaminated fluids in civil, industrial, and municipal environments — especially where ATEX-certified Ex d equipment is required.

Equipped with a set-back vortex impeller, this pump offers exceptional solids-handling up to 80 mm, while maintaining excellent reliability and hydraulic efficiency. It is best suited for large sump pits, sewage lift stations, and explosive or corrosive environments where maximum performance and ATEX compliance are a must.

FEATURES

• ATEX Ex d Certified — Safe for explosive atmospheres (Ex db IIB T4 Gb, Ex h IIB T4 Gb)
• High Solids Handling — Set-back vortex impeller with 80 mm free passage
• Rugged Cast Iron Construction — Casing and impeller in EN-GJL 250 for superior durability
• Heavy-Duty Motor — 2-pole motor with high-speed operation for maximum flow
• Dual Silicon Carbide Mechanical Seals — Enclosed in a large oil chamber with leakage detection sensor
• Universal Cable Gland — GAS thread design accepts sheathing for enhanced cable protection
• Wet Installation — Designed for use with base plate (ZENS9024.114) for free-standing operation
• Pressure Tested — Factory-tested for seal and gasket integrity
