China wholesale HH High Pressure Centrifugal Pump to Italy Factory Detail:
Type AH, HH, M pumps are cantilevered, horizontal, centrifugal slurry pumps. They are designed for handling abrasive or corrosive slurry in the metallurgical, mining, coal, power, building material and other industrial departments etc.
AH(R), HH are also called heavy duty slurry pumps, are used to transport the strong abrasive high density or low density high head slurry. Under the allowable pressure, the pumps of this type also can be installed in multistage series. HH type pump is mainly used for transport low density high head or high density low abrasive high head slurry.
M(R) is a kind of middle duty slurry pump, is used to transport the fine particle size and middle density slurry.
The liner and impeller of AH(R) and M(R) model can be changeable and material can be either anti-abrasive metal or rubber, but material of liner and impeller of HH model only can be metal version. Rubber material wet parts are mainly used for transport the slurry which contains fine, non-sharp particle size.
The shaft seals for type AH(R), M(R) and HH pumps can be adoptable of gland seal, expeller seal and mechanical seal. The discharge can be positioned at intervals of 45 degrees by request and oriented to any eight positions to suit installations and applications.
1. Discharge branch can be positioned at intervals of 45 degree.
2. Good replaceability of components with original pump.
3. Wear-resistant metal and long service life time.
4. With greater axial and radial load rating capacity,
5. Discharge direction can be installed at intervals of 45 degrees as request and oriented to any eight positions to suit applications.
6. Suit different working condition.
7. Wide application, high efficiency and easy to maintain.
8. Wide options for impeller.
9. Bearing assembly use grease lubrication.

What is GOLD DREDGE? What does GOLD DREDGE mean? GOLD DREDGE meaning, definition & explanation.
Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license.
A gold dredge is a placer mining machine that extracts gold from sand, gravel, and dirt using water and mechanical methods.
The original gold dredges were large, multi-story machines built in the first half of the 1900s.
Small suction machines are currently marketed as “gold dredges” to individuals seeking gold: just offshore from the beach of Nome, Alaska, for instance.
A large gold dredge uses a mechanical method to excavate material (sand, gravel, dirt, etc.) using steel “buckets” on a circular, continuous “bucketline” at the front end of the dredge. The material is then sorted/sifted using water. On large gold dredges, the buckets dump the material into a steel rotating cylinder (a specific type of trommel called “the screen”) that is sloped downward toward a rubber belt (the stacker) that carries away oversize material (rocks) and dumps the rocks behind the dredge. The cylinder has many holes in it to allow undersized material (including gold) to fall into a sluice box. The material that is washed or sorted away is called tailings. The rocks deposited behind the dredge (by the stacker) are called “tailing piles.” The holes in the screen were intended to screen out rocks (e.g., 3/4 inch holes in the screen sent anything larger than 3/4 inch to the stacker).
The basic concept of retrieving gold via placer mining has not changed since antiquity. The concept is that the gold in sand or soil will settle to the bottom because gold is heavy/dense, and dirt, sand and rock will wash away, leaving the gold behind. The original methods to perform placer mining involved gold panning, sluice boxes, and rockers. Each method involves washing sand, gravel and dirt in water. Gold then settles to the bottom of the pan, or into the bottom of the riffles of the sluice box. The gold dredge is the same concept but on a much larger scale.
Gold dredges are an important tool of gold miners around the world.They allow profitable mining at relatively low operational costs. Even though the concept is simple in principle, dredges can be engineered in different ways allowing to catch different sizes of gold specimen. Hence the efficiency of gold dredges differs greatly depending on its specifications.
