The EJCY series of vacuum-assisted self-priming centrifugal pumps delivers a highly reliable pumping performance, engineered for wellpoint dewatering systems and construction-site sump drainage. Each unit is built around the heavy-duty EJ/EJT pump, capable of handling liquids with suspended solids – for full specifications, see the EJ/EJT brochure.
Core Components and Performance
At the core of every EJCY unit operates a heavy-duty EJ/EJT series self-priming centrifugal pump, designed to handle liquids carrying suspended solids (for detailed pump specifications, please refer to the EJ/EJT series brochure).
Core Technology Structure and Principles
Integrated tightly with the liquid pump casing, a dedicated separator creates an efficient air‑liquid separation chamber. Here, air or entrained gases are effectively separated from the fluid and extracted by a vacuum pump.
Technical Advantage
This vacuum‑assisted technology enables “dry” priming—without the need to pre‑fill the pump casing with liquid—and allows the unit to manage significant volumes of air.
Application Effect
The system can quickly prime a wellpoint system and maintain it under vacuum, ensuring thorough drainage of excavations even under challenging “snore” conditions.
