Zenit DRBLUE40/2/G32VMGEX Cast Iron 0.3kW Submersible Drainage Pump for Residential Drainage with Open Impeller

Residential drainage systems often face challenges with slightly dirty water accumulation that must be evacuated promptly to prevent damage. This Zenit submersible pump provides an ideal solution for clearing basements, rainwater sumps, and domestic seepage areas. Engineered for domestic duty, it thrives in wet installations where consistent performance is needed for light drainage tasks.

The unit is capable of reaching a maximum flow of up to 210 L/Min and a maximum head of approximately 7 m. Driven by a 0.3 kW single-phase motor at 240v, it provides sufficient hydraulic lift for standard residential transfer applications. This performance profile ensures that liquid is moved effectively while maintaining a low power draw and high operational stability during use.

Hydraulic design centers on an open channel impeller that is fully submerged for optimal cooling and flow behavior. This configuration is specifically engineered to handle liquids containing small suspended solids up to 7 mm, preventing the clogging issues associated with standard centrifugal designs. The submerged installation assists motor cooling during continuous operation, maintaining hydraulic efficiency over long periods.

Structural durability is provided by the cast iron EN-GJL 250 construction, which is built to withstand domestic service environments. Protection features include a double mechanical seal with silicon carbide and alumina graphite faces to prevent liquid from entering the motor housing. Rated for 40°C maximum liquid temperature, the unit also includes an integrated float switch for automated startup and shutdown.
