Dragflow heavy-duty pumps have been designed and built to work especially in burdensome conditions where generally normal pumps cannot operate.

Our advanced design is based mainly on the agitator which is fixed on the main shaft.

Dragflow agitator enables our pumps to rise and convey liquids and mixtures with medium-high specific weight such as mud, slimes, silts, sand and gravel with sizes up to 120mm.
Our pumps can work in such bad conditions thanks to the special materials used to construct every pump. Agitator, impeller, lower and upper wear plate have been made of cast iron, including 30% chrome. dedecms.com
That means a hardness of about 600HB / 650HB and, as a consequence, an incomparable abrasion resistance.
HEAVY DUTY SUBMERSIBLE PUMPS RANGE
Heavy-duty submersible pumps with agitator are available either in hydraulic or in electric version.
- Electric version power output: from 3.7kW up to 110kW
- Hydraulic version power output: from 9kW up to 300kW
The pump can be equipped with cutters, which coupled with the agitator stir up the solids settled on the bottom in order to be easily pumped out and creating a homogeneous mixture with higher percentage of solids, getting a higher efficiency. 本文来自织梦
Please consider that Dragflow is the sole manufacturer of cutters in Europe. 织梦好，好织梦

DREDGES
Dragflow leads this field into the innovative design of systems, able to improve productivity and to minimize downtime. Our products are well known for pumping large quantities of solids by the agitator and the cutters, which put in suspension the material settled at the bottom. Thanks to such features, Dragflow pumps deliver a higher quantity of dry tons per hour, than any other dredging system.

MODULAR AND TRANSPORTABLE DREDGING UNITS
In addition, based on its long-term experience in submersible pumps, Dragflow has started to design and manufacture modular and transportable dredging units. 织梦好，好织梦
The use of simple components means low cost and easiness of maintenance, simplicity to repair possible breakdowns and low prices of spare parts. 内容来自dedecms
As a result of flexibility of our equipment and modularity of its components, Dragflow can manufacture different types of dredges to comply with the different client requests. On demand, we can supply dredges in accordance to the rules of the Italian Naval Registration (R.I.N.A.). dedecms.com
We are able to supply also automated and unmanned dredges and remote controlled dredges. These equipments let minimize labour and maximizing production of solids at the set flow rate.
