Dragflow was founded in the late 1980's as a<br />

manufacturer of high quality submersible<br />

dredging pumps for the European market.<br />

With early successes we expanded the product<br />

line to a full range of electric and hydraulic<br />

pumps and small turn key <strong>dredge</strong>s.<br />

Through our commitment to quality products,<br />

dependable service and continuous<br />

improvement dragflow has become<br />

established worldwide as the pump of choice<br />

for severe service conditions where other<br />

pumps fail.<br />

Dragflow North America offers the<br />

toughest Slurry Agitator Submersible Pumps<br />

and Dredges in the Industry for handling rocks,<br />

gravel, sand, minerals, bentonite, bitunen and<br />

others, with the shortest delivery times to the<br />

US market.

Dragflow Submersible Pump and Cutter Features<br />

DRAGFLOW PUMPS are very heavy duty<br />

submersible pumps capable of handling sand<br />

and slurries with up to 5 inch rocks. The slurry<br />

can be piped to its destination eliminating haul<br />

trucks, conveyor belts and other mechanical<br />

earth moving equipment. Using Dragflow pumps<br />

saves labor and maintenance costs.<br />

All you need is water and power. Pumps are<br />

available with electric or hydraulic motors.<br />

With its incorporated agitator the pump will dig<br />

into the material and is capable of handling up<br />

to 70% solids by weight.<br />

Optional water jets and cutter heads (shown in<br />

picture) allow these pumps to disaggregate and<br />

pick up sediments in a slurry of high density and<br />

high specific gravity.


The excavating action is created by the hardened high chrome agitator blades. They create a<br />

current that lifts settled sediments conveying them to the suction of the impeller which delivers<br />

a continuous flow of solids to the pump discharge.<br />


Low operating RPM promotes low wear rates and extended component life. When compared to<br />

other pumps of similar capacity Dragflow has a lower operating speed. For example the EL-150<br />

has an amazingly low operating speed of 650 rpm.<br />


All Dragflow electric motors are oversized and are designed for slurries up to 1.6 SG. An<br />

Hydraulic drive version is also available providing higher output. Dragflow hydraulic augers EXHY<br />

can be attached directly to the pump creating a self contained excavating system for hard<br />

compacted sand where a mechanical excavator would otherwise be required.<br />


Long life and reliability are guaranteed by robust heavy-duty construction. Extra strong wear<br />

components provide extended life between spare part changes. El-150 weights 3,500 Kg. which<br />

is significantly heavier than comparable 150 HP sand pumps. All parts that are exposed or<br />

subjected to abrasive wear are manufactured in GS 500 or Hi Chrome alloys.


All Dragflow models have been designed with dual thrust bearings to reduce vibration and<br />

counter thrust loads in both directions.<br />


Dragflow sand pump parts have been specially designed and shaped to provide outstanding<br />

performance, providing superb solids handling capabilities but with reduced wear (and solid size<br />

up to 120 mm).<br />


Adjustable Hi-Chrome suction side Wear Plate maintains maximum performance for extended<br />

periods by a simple adjustment of the gap between the wear plate and the impeller.<br />

Service Bolt: These bolts allow easy pump disassembly, a built in service tool.<br />

Replaceable wear parts: casings, impellers, wear plates all can be replaced independently<br />

Reversible agitator: doubles the life of the agitator<br />

Lube Oil Inspection Ports: A wide-angle port outside the pump ensures easy inspection of shaft<br />

seal oil levels as well as providing easy access for oil replacement.<br />


Dragflow pumps are being used in the world’s harshest environments. Our global sales and<br />

service network ensures that we provide the highest level of sales and after-sales service.<br />

Dragflow's Authorized Distributors are located across the United States, including Western USA,<br />

Northeast USA, MidWest USA, SouthEast USA and SouthWest USA.

Dragflow North America offers the toughest Submersible Slurry Agitator Pumps and Dredges in<br />

the Industry for handling rocks, gravel, sand, minerals, bentonite and others, with the shortest<br />

delivery times to the US market. Manufactured in Italy, Dragflow pumps delivers massive solids<br />

production at very low operational costs.<br />

Electric and hydraulic pumps, cutters, excavators, and multiple accessories are integrated in<br />

Powerful Dredges with Operator Cabins on Board or Remote Controlled Dredges of diverse<br />

configurations including the latest Amphibious Multipurpose Dredge. Hydraulic Power Packs,<br />

Umbilical Oil Hoses on Hydraulic Reels, Booster Pump Stations and others, are part of the<br />

diversity of products that complement the highest head submersible slurry pump available in<br />

the industry. These units, capable of working at depths of 300+ feet, in adverse conditions, can<br />

pick up 4.5 inch solids in a 1.6 Specific Gravity Slurry at 70% solids by weight.
