Dredging Pump / Submersible Slurry Pump Features

Dragflow dredging / slurry pump and cutter features

 

DREDGING PUMP / SUBMERSIBLE SLURRY PUMP FROM DRAGFLOW

 

Our very heavy duty dredging pumps /submersible slurry pumps /sludge pumps /sand pumps are capable of handling sand and slurries with up to 5-inch rocks.

The slurry can be piped to its destination eliminating haul trucks, conveyor belts, and other mechanical earth-moving equipment. Using Dragflow pumps saves labor and maintenance costs.

All you need is water and power. Pumps are available with electric or hydraulic motors.

With its incorporated agitator, the pump will dig into the material and is capable of handling up to 70% solids by weight.

Optional water jets and cutter heads (shown in picture) allow these pumps to disaggregate and pick up sediments in a slurry of high density and high specific gravity.

FIFTEEN REASONS FOR CHOOSING DREDGING PUMPS / SLURRY PUMPS FROM DRAGFLOW

 

1. HIGH-EFFICIENCY HIGH CHROME REVERSIBLE AGITATOR

Doubles the life of the agitator. The excavating action is created by the hardened high chrome agitator blades. They create a current that lifts settled sediments conveying them to the suction of the impeller which delivers a continuous flow of solids to the pump discharge.

2. LOW OPERATING RPM

Low operating RPM promotes low wear rates and extended component life. When compared to other pumps of similar capacity Dragflow has a lower operating speed. For example, the 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 up to 1.6 SG. A Hydraulic drive version is also available providing higher output. Dragflow hydraulic augers EXHY can be attached directly to the pump creating a self-contained excavating system for hard compacted sand where a mechanical excavator would otherwise be required.

4. ROBUST CONSTRUCTION

Long life and reliability are guaranteed by robust heavy-duty construction. Extra strong wear components provide extended life between spare part changes. El-150 weights 7,720 lbs (3,500 Kg.) which is significantly heavier than comparable 150 HP slurry pumps. All parts that are exposed or subjected to abrasive wear are manufactured in GS 500 or Hi Chrome alloys.

5. THRUST BEARINGS

All Dragflow models have been designed with dual thrust bearings to reduce vibration and counter thrust loads 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 and solid size up to 5 inch (120 mm).

7. STRUCTURAL CHARACTERISTICS

Adjustable Hi-Chrome suction side Wear Plate maintains maximum performance for extended periods by a simple adjustment of the gap between the wear plate and the impeller.

Service Bolt: These bolts allow easy pump disassembly, a built-in service tool.

Replaceable wear parts: casings, impellers, wear plates all can be replaced independently

Lube oil inspection ports: A wide-angle port outside the pump ensures easy inspection of shaft seal oil levels as well as providing easy access for oil replacement.

8. LARGEST RANGE OF SUBMERSIBLE PUMPS

From 5 HP to 400 HP and discharge diametes from 3" to 16" 

9. HIGH HEAD PUMP IN THE MARKET

Handling slurries of up to 1.6 SG.

10. OPTIONAL MECHANICAL SEAL, LIP SEAL OR HYBRID SEAL SYSTEMS

According to the application.

11. CUTTERS HEADS AVAILABLE 

Both Hydraulic and Electric, for hard compacted soil.

12. OPTIONAL WATER JETS RING SYSTEM

For hard compacted soil and very dry materials.

13. OPTIONAL PRESSURE COMPENSATORS

For applications at great depth.

14. OPTIONS FOR SEVERAL APPLICATIONS

High chrome casing, Cooling Jacket, Anti corrosion package, Anti abrasion package, Lower membrane proctection, Cutter knife, Temperature and moisture sensors, custom frames to fix the pump in the boom of excavator machines.
