Tobee TH8/6E Low Volume High Pressure Slurry Pump

Tobee^® TH8/6E Slurry Pumps are also widely used for the disposal of ash from thermal power plants. Other areas where slurry pumps are used include the manufacture of fertilizers, land reclamation, mining by dredges, and the long distance transportation of coal and minerals.

Slurry Pump Parts:

Impeller
The impeller, either elastomer, stainless steel or high-chrome material, is the main rotating component which normally has vanes to impart the centrifugal force to the liquid.
Casing
Split outer casing halves of cast contain the wear liners and provide high operation pressure capabilities. The casing shape is generally of semi-volute or concentric, efficiencies of which are less than that of the volute type.
Shaft and Bearing Assembly.
A large diameter shaft with a short overhang minimizes deflection and vibration. Heavy-duty roller bearing are housed in a removable bearing cartridge.
Shaft sleeve
A hardened, heavy-duty corrosion-resistant sleeve with O-ring seals at both ends protects the shaft. A split fit allows the sleeve removed or installed quickly.
Shaft Seal
Expeller drive seal, Packing seal, Mechanical seal.
Drive Type
V-belt drive, gear reducer drive, fluid coupling drive, and frequency conversion drive devices.

Typical Applications:

Mining & Mineral Processing
The slow running speeds of the Tobee AH Heavy Duty Slurry Pump, together with the comprehensive choice of abrasion resistant alloys and elastomers, provide unrivalled performance and service life for all abrasive mining and minerals processing applications.

Chemical Process
The interchangeability of alloy and elastomer components in the same pump casing, together with a wide range of mechanical seals, make the Tobee AH Heavy Duty Slurry Pump the most flexible choice for the chemical plant environment.

Sand & Gravel
Designed for easy and simple strip down and re-assembly, the Tobee AH Heavy Duty Slurry Pump minimises downtime, making it the ideal choice where installed stand by pumps are not available.

Sugar Processing
The premium reliability and service life of the Tobee AH Heavy Duty Slurry Pump is specified by many sugar plant engineers worldwide where uninterrupted pump operation during the sugar campaign is a critical requirement.

Flue Gas Desulphurisation
The new generation of specially formulated abrasion and corrosion resistant alloys, together with the very latest elastomer technology, positions Tobee Pumps firmly as a major supplier of pumps to the FGD industry.

Oil & Gas Exploration
Over a number of years we have developed the proven design of the Tobee AH Heavy Duty Slurry Pump ranges to suit the specific demands of offshore applications. We can now offer the most reliable top side solution to erosive wear.

Industrial Applications
Wherever abrasive solids are causing premature failure of pumps, the Tobee AH Heavy Duty Slurry Pump range has the right combination of performance, wear life and reliability to bring the customer the lowest cost of ownership.

Tobee^® 8x6inch Heavy Duty Slurry Pump Shaft Seal Arrangement:

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:
TH 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. Tobee pump also utilizes special ceramic and alloys of high strength and hardness on parts that are subjected to friction. Unique design of and seamless fit between the mechanical seal and seal chamber provides excellent resistance to abrasion and shock that ensures its effectiveness under the toughest conditions.
