1.1 MH Series Centrifugal Mining Slurry Pumps Description:

Sand Excavation Slurry pump is used for delivering slurry with strong abrasion and high concentration for metallurgy, mines, coal and power plant, etc.Such as, Ore Slurry ,Coal Slurry ,Slag Slurry ,Ash Slurry ,Lime Slurry etc.

Sand slurry pump's body is used double-deck structure, in other words, being made of inside lining and outside shell.

1.2 MH Series Centrifugal Mining Slurry Pumps Installation:

Mining slurry pump's body is used double-deck structure, in other words, being made of inside lining and outside shell.The discharge can be oriented to any 8 positions by 45 degrees to suit installations and applications.

1.3 Features

1. Cantilevered, horizontal, centrifugal,single stage slurry pump
2. Widely application: the slurry pumps are designed for handling abrasive, high density slurries in the metallurgical, mining, coal, power, building material and other industrial departments.
3. Long bearing life: The bearing assembly is with large diameter shaft and short overhang. 
4. Easily replaceable liners: Liners are bolted to the casing.
5. Simple maintenance throat-bush: the mating face of the throat bush is tapered, so the wear is reduced and removal is simple.
6. Easy adjustment of impeller: An impeller adjustment mechanism is provided below the bearing housing.
7. High efficiency and high head design are also available.
8. Sealing type: packing seal, impeller sealing and mechanical seal. 

1.4 Seal type

There are three standard shaft seal methods: Packing seal, Expeller seal, Mechanical seal.

Packing Seal :
As one of the most commonly used seals for rotating shafts, the packing seal can come with low-flush or full flush arrangement which uses flushing water to prevent media from escaping the pump housing. This kind of seal is suitable for use under all pumping conditions. In situations where corrosive solids or high temperature might be encountered, Teflon or aramid fiber is used as the packing material for the gland. For high abrasion conditions, a ceramic shaft sleeve is available.

Expeller seal:

The combination of impeller and expeller creates the pressure needed to seal against leakage. Together with the gland seal or lip seal which is used as the shut-down seal, this type of seal can handle sealing requirements for applications where full-flush gland seal is impractical due to lack of water on the site, or sealing water is allowed to enter inside the pumping chamber to dilute the slurry.

Mechanical Seal :

MH series heavy duty slurry pump utilizes a leak-proof mechanical seal design which allows easy installation and replacement. Other types of mechanical seal are among options to suit the slurry pump for various pumping applications.
