Technical Specifications of Dragflow EL 1204 HH
The pump is designed for powerful performance in sediment-heavy environments:
Flow Capacity
100 m³/h to 300 m³/h
Motor Power
75 kW to 90 kW
Head Capacity
28 m to 72 m
Solids Handling Capability
Specific gravity up to 1.6 t/m³
More than 70% solids concentration by weight
Construction Features

Engineered for Harbour Dredging Operations
Harbours and ports continuously accumulate sediment due to tidal movement, river inflow, and marine activity. Without regular dredging, navigation channels become shallow and unsafe.
The Dragflow EL 1204 HH is ideal for:
Port maintenance dredging
Navigation channel deepening
Sediment removal in harbours
Dock and berth cleaning
Marina maintenance projects
Its integrated agitator ensures continuous suspension of solids, allowing efficient pumping even in dense seabed material.
Dam Dredging Equipment for Water Infrastructure Maintenance
Dams and reservoirs gradually lose capacity due to sediment accumulation. Efficient Dam Dredging Equipment is required to restore storage capacity and maintain water quality.
The EL 1204 HH supports:
Dam sediment removal
Reservoir cleaning and restoration
Irrigation system maintenance
Flood control improvement
Water capacity recovery projects
Its high solids handling capability ensures efficient removal of thick sediment layers.
