Zenit DRE100/2/G50HMGSIC A0 Cast Iron Automatic Drainage Pump for Site Dewatering with Open Impeller

Site dewatering tasks require a robust submersible pump capable of managing rainwater runoff and groundwater seepage from excavations or collection pits. This professional Zenit model is designed to handle slightly soiled liquids in construction and site environments, ensuring that water levels are managed effectively to maintain safe working conditions. Its rugged build is specifically suited for wet installations where continuous reliability is critical.

Hydraulic performance is tailored for dewatering, delivering a maximum flow of up to 540 L/Min and approximately 12.5 m of maximum head. Driven by a 0.9 kW motor on 240v single-phase power, the pump provides consistent discharge capacity to clear site pits quickly. This unit's design is optimized for professional duty, ensuring it can handle the varied inflow rates common in dewatering scenarios.

The unit features an open channel impeller, specifically engineered to pass slightly soiled water without hydraulic compromise. This design facilitates smooth liquid handling while preventing internal clogging from small suspended solids or site debris. The submerged installation assists motor cooling during continuous operation, allowing the unit to maintain stable performance during periods of intensive use.

Mechanical construction utilizes a heavy-duty cast iron EN-GJL 250 body and a stainless steel shaft for maximum durability in harsh environments. Protection is provided by a mechanical seal in silicon carbide with an auxiliary lip seal for enhanced motor safety. Rated for liquid temperatures up to 40°C, the unit includes an integrated float switch for automatic level regulation on site.
