Ceramic Slurry Pump

Heavy Duty Submersible Slurry Pumps from  Dragflow

Dragflow manufactures electric and hydraulic Submersible Slurry Pumps.

All Dragflow slurry pumps, Electric and hydraulic, has the following characteristics:

Standard high efficiency agitator to lift settled solids

High abrasion resistance with high chrome wearing parts

Low rotation speed to reduce wearing effect

Able to handle up to 70% of solids by weight

Electric pumps are available in 60Hz and 50Hz versions. Pumps are CE certified. UL/CSA certification available.

We have pumps from 5 HP to 400 HP with capacities up to 6000 US gpm.

In the products section of this website you can find our pumps and their specifications.

In the documents section you can download our products catalogues and the data sheets of our products as well.

We also provide Electric Control Boxes for our Electric slurry pumps and Hydraulic Power Packs (based on diesel engines or electric motors) specifically designed to drive our hydraulic slurry pumps.

The hydraulic slurry pumps could be retrofitted in the boom of a hydraulic excavator.

Slurry Pump accessories

Cutter heads:

Hydraulic or electric cutter heads could be attached directly to the pump for compacted materials.



Water Jets Ring System:

A High pressure water jets ring system could be used for dry materials. It consists of a jet rings frame mounted on the pumps strainer and a high pressure water pump.

Mechanical seal:

Dragflow standard sealing system is its superb lip seals combination. A double silicon carbide mechanical seal in combination with a front deflector is available as an option for very abrasive applications.

Cooling Jacket:

Dragflow pumps from 3.7 to 18 kW come with top discharge that creates a natural cooling jacket for the pump. This allows the pump to work even if not completely submerged. An external cooling jacket can be available also for pumps bigger than 26kW and up to 110 kW thus allowing all the range to work also in semi-submerged conditions.

Anti-corrosion package:

 In cases of high or low pH pump strainer and lifting plates can be supplied in stainless steel (316SS). This choice together with Teflon layers in the seal zone makes Dragflow pumps suitable for environments with pH from 2 to 10."

Automatic greasing system:

Pumps installed can be equipped with an automatic greasing system that provides fresh grease to the seals on a regular basis.

This operation not only increases the overall sealing system life but also allows the operators to dramatically reduce maintenance and checks on the pump.

Anti-abrasion package:

The quality and type of casting used in Dragflow pumps are designed to face the most difficult and abrasive applications. For some specific applications an extra hardened coating layer can be applied inside the pump casing.

Hardened casing:

Pumps can be supplied with a hardened casing to ensure long life to this part. Beside our standard cast iron casing, we have available casings in S6 and High Chrome.

Lower Membrane protection:

Often the bottom of mine ponds is covered with a water-proof plastic lining.

Action of the pump during dredging operation could damage this lining. With Dragflow you have the option to add a protective ring to the pump strainer in order to prevent any damage.

Weed cutter-knife:

When the slurry is covered by a layer of vegetation, grass or seaweed, Dragflow cutter knife will help the pump to perform the task without clogging

Temperature and Moisture Sensors:

Temperature sensor, embedded in the motor; and Moisture sensor, in the oil chamber, are available to protect the pump in the most demanding applications.

Pump frames:

Dragflow pumps are used in several sectors. Custom frames can be supplied to for specific applications.

Flow rate dividers:

Dragflow have available Flow Rate Dividers to divide the oil flow (delivered by the hydraulic power pack) between the pump and the cutter heads, depending of the required configuration

Hoses and Pipes:

We have available flexible dredging hoses, HDPE Pipes and floaters in different diameters. Our commercial staff will be glad to support you in the selection of the discharge pipe line.
