High pressure portable diesel self-priming pump

EJCY Series Energy Efficient Self Priming Pump for Industrial Water Systems

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.
