Heavy duty slurry pumps for a
range of mill duties, from dirty water to the most difficult water
flushed crusher services
The Warman® AH®
pump is the world’s standard for the most difficult mill
duties. A wide variety of impellers and shaft seals provide a
perfect fit for a wide range of applications. The AH®
pump provides excellent wear life while maintaining efficiency
during the wear cycle providing the best total operating cost. The
Warman® AH® pump, together with the
Warman® MC series pump, provides
a complete selection for most all duties in the mill. From cyclone
feed to regrind, flotation and tailings, the Warman®

- 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.
- 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 molded
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 molded
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.
