Pump type MA is the standard heavy duty slurry pump which designed for the continuous pumping of highly abrasive, high density slurries with
minimal maintenance requirements. It maintains high efficiencies over the wear life of its components. This type of pump typically used in heavy
minerals processing, mineral recovery process plant transfers, wet waste processes, recycling-washing plant, sand plant duties and chemical
process plant. Typical Application
Mill Discharge
Coarse Sand
Tailings
Mineral Concentration
Heavy Media
Coal Washing
FGD
Chemical Processing
Bottom/Fly Ash
Metal Smelting

3. 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.

M26R is soft natural rubber, normally used for liners, and is required in fine
particle slurries applications.
M33R is a premium grade material for use where M26R does not provide
sufficient wear life.
M38R is a black natural rubber, of medium hardness, M38R is used for impellers
where superior erosive is required in find particle slurries.
M55R is a premium grade material for use in a high wear application. Superior
physical properties give increased cut resistance to hard, sharp particle slurries.
M02S is an acid resistant rubber which is of medium abrasion resistance.
M12S is synthetic elastomer which is generally used in low abrasion/erosion
application. It provides excellent resistance to oils, fats and waxes.
M21S exhibits excellent chemical stability and good resistance to heat and
oxidation. It is generally used in acidic applications.
M31S exhibits an excellent balance of chemical resistance to both hydrocarbons
and acids.
M42S provides improved resistance to temperature, weather and ozone attack. It
has excellent oil resistance.
M51S has exceptional resistance to oils and chemicals at elevated temperature.
Limited erosion resistance.
