Zenit DRE200/2/G50HMGSIC A0 Cast Iron Automatic Drainage Pump for Heavy Drainage with Open Impeller

Heavy drainage applications require a powerful submersible unit capable of managing high inflow rates and significant hydraulic head. This automatic Zenit model is designed for professional site management, clearing soiled liquids from deep excavation pits, high-volume sumps, and industrial groundwater collection areas. Its integrated level control and robust build make it a preferred choice for sites requiring rapid, autonomous liquid turnover.

Hydraulic capability is a standout feature, delivering a maximum flow of up to 720 L/Min and reaching approximately 18.1 m of maximum head. The 1.5 kW motor operates on 240v single-phase power, providing substantial force for demanding heavy drainage tasks. This performance profile is engineered to clear large volumes of liquid efficiently, ensuring site safety and operational continuity during heavy rain or seepage.

The unit utilizes an open channel impeller, specifically configured to handle liquids containing small suspended solids common in heavy-duty drainage. This configuration promotes consistent fluid turnover while minimizing the risk of internal blockages that could stall operations. The submerged installation assists motor cooling during continuous operation, supporting lasting performance in demanding conditions.

Mechanical design features a rugged cast iron EN-GJL 250 body paired with a stainless steel AISI 431 shaft for superior mechanical resilience. Sealing is provided by a mechanical seal in silicon carbide with an auxiliary lip seal for enhanced motor protection. Rated for liquid temperatures up to 40°C, the unit includes an integrated float switch for fully automatic level management.
