Technical Specifications
Tobee® Heavy Duty Slurry Pumps
The heavy duty TH slurry pump range is designed to perform continuous pumping of highly
abrasive/dense slurries in processes from hydrocyclone feed to regrind, flotation and
tailings in minerals processing plants as well as other industrial applications.
Design Features
• Bearing assembly – a large diameter shaft
with short overhang minimizes deflection and
contributes to long bearing life. Only four
through bolts are required to hold the cartridge
type housing in the frame.

Above: Metal Lined, Rubber Lined, Polyurethane
Lined, Ceramic Lined is available
• Ball mill discharge
• Bottom/fly ash, lime grinding
• Coal
• Coarse sand
• Coarse tailings
• Dredging
• FGD
• Fine tailings

• Phosphoric acid
• Phosphate matrix
• Process chemical
• Pulp and paper
• Rod mill discharge
• SAG mill discharge
• Wet crushers
• Liners – easily replaceable liners are bolted,
not glued, to the casing for positive attachment
and ease of maintenance. Hard metal liners
are completely interchangeable with pressure
moulded elastomer.
• Elastomer seal rings back all liner joints.
• Casing – Casing halves of cast or ductile iron
with external reinforcing ribs provide high
operating pressure capabilities and an extra
measure of safety.
• Impeller – front and rear shrouds have pump
out vanes that reduce recirculation and seal
contamination. Hard metal and moulded
elastomer impellers are completely
interchangeable.
• Cast in impeller threads require no inserts or
nuts. High efficiency and high head designs are
also available.
• Throatbush – wear is reduced and
maintenance simplified by the use of tapered
mating faces to allow positive accurate
alignment during assembly and simple
removal.
• One-piece frame – a very robust one-piece
frame cradles the cartridge type bearing and
shaft assembly.
• An external impeller adjustment mechanism is
provided below the bearing housing for easy
adjustment of impeller clearance.
