Typical Application
The MH high head slurry pump is cantilevered, horizontal, centrifugal slurry pump, which is specifically designed to combat the need to run
conventional design slurry pumps at excessive speeds to generate high heads often required in many modern slurry pumping applications. Single
pump unit rather than series pumping can be adopted, at greatly reduced capital cost, while still offering optimum wear life and efficiency.

Centrifugal Seal or Expeller Seal or Dynamic Seal-The centrifugal seal consists of expelling vanes on the back of the impeller and an
expeller which rotates in unison with the impeller. The expeller is located in a separate chamber behind the impeller. The expeller acts
as a turbine to reduce the pressure of the slurry attempting to escape around the back of the impeller. The expeller forms a pressure
ring within the expeller chamber and prevents the slurry from passing into the secondary seal area.
Gland Seal-The gland seal comprises a number of soft packing rings, compressed in a chamber (stuffing box) against a protective wear
sleeve which fitted to the pump shaft. This type of seal requires continuous clean flushing water lubrication and cooling between the
rotating shaft sleeve and the compressed packing, to prevent over heating due to the friction.
Mechanical Seal-When it is essential for the leakage to be prevented entirely, then mechanical seals should provide a solution. The
mechanical seal consists of a stationary and rotating face pressed together under mechanical and hydraulic pressure to prevent leakage.

Alloy M05 is particularly suited for greater impact load and fair
corrosion resistance, and it is used when pH range is 5-12.
Alloy M07 has lower wear resistance but higher impact resistance
than Alloy M05. It is used when pH range is 5-12.
Alloy M49 has certain erosion resistance and better corrosion and
abrasion resistance, which is used in mild acid application with pH =4,
particularly suitable for Flu Gas Desulphurization (FGD) applications.
Alloy M33 excels in erosion resistance and corrosion resistance, which
can be used in oxidizing medium with pH =1, such as delivery of
phosphogypsum and nitric acid, sulfuric acid and phosphoric acid, etc.
Alloy M12 has better wear resistance than Alloy M05, but it is not best
suited for corrosion application. It can be selected when pH ranges of
6-14, where Alloy M05 provides fair wear life.
Alloy M61 has better toughness compared to Alloy M12. Alloy M61
can be further hardened by adjusting heat treatment, thereby improve
its wear resistance. It is suitable for high abrasive slurry with fine
particles with pH ranges of 6-14.

A major advantage of the slurry pump is the number of optional materials avaliable. This enables a pump to be constructed with the
most appropriate materials specifically to meet the duty requirements.
