A solid transport device

DRAGFLOW PUMPS, are Italian dredging submersible pumps capable of handling slurries with up to 5 inches rocks and sand, convey it in a pipeline and deliver it to destination without the usage of trucks, conveyor belts and other mechanical means that are very labor intensive and create maintenance nightmares.

All you need is water and electricity or a hydraulic power pack to operate successfully.

With the pump literally in the material, DRAGFLOW with its incorporated agitator is capable of handling up to 70% solids by weight.

Options like water jets or special cutter heads are accessories that could make your DRAGFLOW unit a complete and autonomous dredging device.

1. HIGH EFFICIENCY AGITATOR
The mixing and excavating movement is created by the Hi-CR steel agitator cutter blades. The lifts and sucks in settled sediments and solids, creating a continuous uninterrupted flow of concentrated slurry into the pump.

2. LOW OPERATING RPM
Lower operating RPM guarantees lower wear rates and prolonged component life. Compared to other pumps of similar capacity Dragflow offers a lower operating speed. For example, the model EL-150 has an amazingly low operating speed of 650 rpm.

3. OVERSIZED MOTORS
All Dragflow electric motors are oversized and are designed for slurries with S.G. up to 1.6 Kg/dm3. Hydraulic driven version is also available in order to grant higher performances for hard compacted sand where a mechanical action could be required to remove it. Dragflow hydraulic excavator/s model EXHY can be coupled directly on the pump.

4. ROBUST CONSTRUCTION
Long life and performance reliability are guaranteed by robust, heavy-duty construction. Extra strong wear components provide a longer life between spare part changes. El-150 weights 3,500 Kg. which is significantly heavier than comparable 110 kW sand pumps. All parts that are exposed or subjected to abrasive wear are manufactured in GS 500 castings or chromium steel alloys.

5. THRUST BEARINGS
All Dragflow models have been designed with dual thrust bearings to reduce vibration and counter thrust drives in both directions.

6. SOLIDS HANDLING CHARACTERISTICS
Dragflow sand pump parts have been specially designed and shaped to provide outstanding performance, providing superb solids handling capabilities but with reduced wear (solid size up to 120 mm).

7. STRUCTURAL CHARACTERISTICS
HC-CR Wear Plate Adjustment: This plate, which is located at the pump inlet, maintains maximum performance for long operational periods simply by the easy adjustment of the gap between it and the impeller.
Forcing Bolt: This bolt facilitates easy disassembly. 
Compartmentalized parts: casings Separation of parts that are subjected to abrasion, allows for partial part replacements 
Lubrication; Inspection of Ports: A wide-angle port outside of the pump ensures easy inspection of shaft sealing oil levels as well as providing easy access for lubrication.
