1. Description of HH high head slurry pump:

HH high head slurry pump is cantilevered, horizontal, centrifugal slurry pump.They are designed for the handling highly abrasive, high density slurries in the metallurgical, mining, coal, power, building material and other industrial departments etc.The pumps of this type also may be installed in multistage series.

Packing Seal of HH high head slurry pump :
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, aramid fiber is used as the packing material for the gland. For high abrasion conditions, a ceramic shaft sleeve is available. 

Expeller seal of high head horizontal slurry pump : 

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 of high head slurry pump :
HH 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.

HH  Slurry Pumps

The frame plates for the type HH slurry pumps have replaceable wear-resistant metal liners or rubber liners.The impellers are made of wear-resistant metal or rubber.

The shaft seals for type HH high head slurry pumps may be adoptable of gland seal or expeller seal.The discharge branch can be positioned at intervals of 45 degrees by request and oriented to any eight positions to suit installations and applications.
