CEMO Pump CTX3 Mobile Dewatering System for Mining

Reliable Mobile Mine Dewatering

All Pumps “Fish Tank” Mobile Dewatering System is designed to provide dependable mine dewatering performance in demanding field conditions. Built for mobility, durability, and ease of maintenance, the system helps mining operations manage water efficiently while minimizing downtime.

Key Features

—

Dewatering Tank: Dewatering Tank improves slurry handling and separation of large solids.

—

Stainless Steel End Covers, Clamp Plates, and Stator Stainless Steel End Covers, Clamp Plates, and Stator for extended service life in saline and harsh mine water conditions.

—

Maintenance-Free Flexible Drive Shaft No pins or wearing rubber sleeves

—

Internal Anti-Reverse Clutch These are available on Mark 1 Models and stop back flow

—

Easy Repair Stator Clamps Much easier to work on than pumps with long connecting rods that hold the pump together. They have proven to be more reliable under pressure in highly corrosive environments.

—

Reliable Belt Drive System Over-engineered and highest quality belts are used to minimize downtime. All systems leave our factory laser-aligned.

—

Pump Transfer Cradle Suitable for removing the pump only when rotating a pump for maintenance, underground minimizing downtime.

CEMO Pump Applications

Open Pit Transfer Pump Station Application

In open pit mining operations, reliable transfer pumping is essential for moving slurry, water, and process fluids across long distances. CEMO pump systems are designed to handle abrasive solids, fluctuating flow conditions, and demanding site environments while maintaining consistent performance.

Underground Mining Application

Underground mining environments require compact, durable pumping solutions capable of operating reliably in confined and challenging conditions. CEMO pump systems support critical underground operations such as dewatering, slurry transfer, and process fluid handling, helping maintain safe and efficient mine operations.

They have proven to be the lowest cost dewatering for underground mining where flows of 100 liters per second or lower are experienced with high discharge head pressures.
