About Hydroman Submersible Dredge Pumps in China

Hydroman was founded in the late 2008's as a manufacturer of high quality submersible dredging pumps for the Chinese market. With early successes we expanded the product line to a full range of electric and hydraulic dredge pumps and small turn key dredges.

Through our commitment to quality submersible slurry pumps, dependable service and continuous improvement Hydroman has become established worldwide as the submersible pump of choice for severe service conditions where other pumps fail.

Hydroman offers the toughest Slurry Agitator Submersible Pumps and Dredges in the Industry for handling rocks, gravel, sand, minerals, bentonite, bitunen and others, with the shortest delivery times to the site. 

Hydroman Submersible Dredge Pump and Side Cutter Features:

HYDROMAN PUMPS are very heavy duty submersible pumps 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 Hydroman submersible dredge pumps saves labor and maintenance costs.

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

Optional iShot™ water jet rings and cutter heads (shown in picture) allow these hydroman submersible pumps to disaggregate and pick up sediments in a slurry of high density and high specific gravity.

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 submersible dredging pump discharge.


Low operating RPM promotes low wear rates and extended component life. When compared to other dredge pumps of similar capacity Dragflow has a lower operating speed. For example the 150TJQ has an amazingly low operating speed of 650 rpm.


All hydroman submersible electric motors are oversized and are designed for slurries up to 1.6 SG. An Hydraulic drive version is also available providing higher output. Hydroman hydraulic cutters ExPro™ can be attached directly to the THY hydraulic slurry pump creating a self contained excavating system for hard compacted sand where a mechanical excavator would otherwise be required. 


Long life and reliability are guaranteed by robust heavy duty construction. Extra strong wear components provide extended life between spare part changes. 150TJQ weights 3,500 Kg. which is significantly heavier than comparable 150 HP submersible sand pumps. All wear parts that are exposed or subjected to abrasive wear are manufactured in GS 500 or High Chrome alloys.


All Hydroman pumps have been designed with dual thrust bearings to reduce vibration and counter thrust loads in both directions.


Hydroman submersible 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 120 mm).


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

Reversible agitator: doubles the life of the agitator

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.


Hydroman pumps are being used in the world's harshest environments. Our global sales and service network ensures that we provide the highest level of sales and after-sales service.
