Energy Efficient Self Priming Pump for Industrial Water Systems

EJCY Series Energy Efficient Self Priming Pump for Industrial Water Systems

EJCY vacuum-assisted self-priming centrifugal pump units are a highly reliable pumping solution, engineered for demanding applications such as well point dewatering systems and construction site sump drainage. 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 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.
