Product Description

                   8 inches Sludge Suction Pumps for hopper dredger

1.Features of G series Gravel Pumps

(1) The G and GH pump is a horizontal cantilevered single casing centrifugal pump

(2) A typical feature of this sand and gravel pump is its one-piece case, connected using clamp bands. This design makes the outlet rotation to any angle. Minimal maintenance is required.

(3) Wide flow passage allows a large volume of slurry to pass. The sand and gravel pump is specially designed to handle high-abrasion applications that ordinary pumps can't even attempt.

(4) One-piece case and wear-resistant hydraulic parts are easy to replace and repair.

(5) The pump head is fixed to the mounting base by a few bolts. Users can adjust the clearance between the impeller and suction liner from underneath a bearing pedestal.

(6) Three shaft seal types are available. Packing seal. Expeller seal and special engineered seal. Users can easily replace one type of seal with another in order suit the specific pumping application.

2.Applications of the single Casing Pumps

The mining gravel pump is used for river course, reservoir desalting, coastal reclamation, stretching, deep-sea mining and tailing acquisition etc.
