Dragflow EL 1204 HH Electric Pump – High Performance for Abrasive Slurries
The Dragflow EL 1204 HH Electric Pump is a high-performance solution designed for demanding dredging, mining, and industrial applications where reliable handling of abrasive solids is essential. Built with decades of engineering expertise, this heavy duty electric submersible slurry pump delivers consistent performance in some of the harshest working environments, including deep water dredging and high-density sediment removal.
Developed by Dragflow, a global leader in solid pumping technology with over 25 years of experience, the EL 1204 HH is engineered specifically for challenging site conditions where conventional pumps fail. From offshore operations to inland dredging projects, this model is widely used across industries requiring continuous, efficient slurry transport.
Engineered for Deep Water and High Head Performance
The Dragflow EL 1204 HH is designed as a deep water dredging submersible pump capable of operating in high head conditions up to 72 meters. This makes it suitable for complex dredging projects where long discharge distances and vertical lift are required.
Key performance highlights include:
High head capacity up to 72 m
Pump capacity range: 100 to 300 m³/h
Heavy-duty electric submersible design
Stable performance under continuous operation
Its robust configuration ensures reliability in both shallow and deep water environments, making it ideal for industrial-scale sediment removal and slurry transport.
Built for Abrasive Slurry and High Solid Content
One of the defining strengths of this electric pump for abrasive slurries is its ability to handle materials with high solid concentration. The pump is engineered for:
Solids with specific gravity up to 1.6 t/m³
High abrasion resistance components
Low-speed operation to reduce wear
Continuous heavy-duty pumping cycles
The integrated agitator helps break down compacted material and ensures smooth solids handling, making it a dependable industrial slurry pump for demanding operations.
