Zenit DRBLUE50/2/G32VMGEX Cast Iron 0.37kW Submersible Drainage Pump for Sump Dewatering with Open Impeller

Sump evacuation in domestic settings requires a submersible unit that can reliably clear rainwater, seepage, and strained wastewater. This model is particularly suited for residential areas where slightly dirty water needs to be moved from collection pits to drainage points. Its design supports continuous operation in wet installations, making it a dependable component for home water management systems.

This unit provides a maximum flow rate of up to 240 L/Min and a maximum hydraulic head of approximately 9.5 m. Its 0.37 kW motor is configured for 240v single-phase supply, delivering balanced hydraulic performance for low-to-medium lift tasks. This performance profile is ideal for applications where consistent evacuation speed is necessary for system safety.

An open impeller is at the core of this pump's hydraulic performance, enabling it to handle small suspended solids effectively. By using a fully submerged impeller design, the unit maintains efficient circulation and minimizes the risk of blockages during standard residential duty. The submerged installation assists motor cooling during continuous operation, ensuring reliable performance without hydraulic compromise.

Mechanical integrity is assured by the cast iron EN-GJL 250 body, paired with an AISI 431 stainless steel shaft for long service life. The pump incorporates a robust sealing arrangement with silicon carbide and alumina graphite to ensure the motor remains dry and protected. Capable of operating in liquids up to 40°C, the unit includes an integrated IECEx float switch for automatic level management.
