Abrasive and corrosive resistant slurry pump for dredger 

Sand Dredger Pump and river dredging pump

1) Cantilevered, horizontal, centrifugal, one stage, single casing gravel (sand) pump

2) High head, large capacity, high efficiency.

3) Good NPSH performance.

4) Widely application: They are designed for handling more abrasive with solids slurries in the river dredging, Sand reclamation, explosive sludge in metal melting, dredging in dredger and course of river and other fields.

5) Long bearing life: The bearing assembly is with large diameter shaft and short overhang.  

6) Wear resistant wet parts: The wet parts are made of Ni hard and high chromium abrasion resistance alloys. (more than 26% Chrome alloy).

7) The frame plate for type KM KA pumps have replaceable wear-resistant metal liners or rubber liners. The impellers are made of wear-resistant metal or rubber.

8) Easy adjustment of impeller: An impeller adjustment mechanism is provided below the bearing housing.

9) Centrifugal seal, mechanical seal and packing seal are available.

10) The shaft seals for type KM KA and KH pumps may be adoptable of gland seal or expeller seal

11) The discharge branch can be positioned at interval of 45 degrees by request and oriented to any eight positions to suit installations and applications.

Pump Parts:

1. All of the metal wet parts can are made of high chromium alloy which has superior wear and erosion resistance or grey iron which has a high rigidity.

2. As the expeller ring is assembled together with the expeller, much pressure can be reduced effectively for the impeller. Meanwhile, it can still maintain a reliable sealing performance.

3. The parts such as labyrinth, labyrinth locknut, end cover and shaft sleeve are used for bearing assembly; these parts can be changed easily and have high accuracy and longer service life.

4. Some fastening parts such as studs and bolts can be used for fixing the other parts securely. All the fastening parts can be attached easily, ensuring the safety.

5. All of the rubber parts have superior erosion resisting performance which can be used for a long life.
