Submersible Sump Pump
EBARA DSJ – Parallel-Alternating Automatic Sump Pump
The EBARA DSJ is an advanced submersible sump pump designed for automatic parallel-alternating operation. Featuring built-in float switch control, rapid motor protection, and robust construction, it provides dependable performance in demanding drainage and water transfer applications.
Key Features
Double mechanical seal in oil chamber with silicon carbide lower faces for enhanced shaft sealing reliability
Built-in motor protector guards against overload, phase failure, and locked-rotor conditions
Automatic parallel-alternating operation allows two pumps (A + J type) to alternate, or operate together under high inflow
Handles solids up to 13 mm (model dependent) and fiber length up to 50 mm
Suitable for continuous use in water temperatures from 0°C to 32°C
