MAH SLURRY PUMP SERIES
MAH Heavy duty horizontal slurry pumps. High efficiency transfer of abrasive and high density slurries with extended wear life and reliable service intervals. MAH pumps feature a rugged cast iron construction with replaceable wear liners available in 27% chrome white iron, rubber or urethane to suit a wide range of applications, slurry types and consistencies. MAH Horizontal Slurry Pumps are 100% fully interchangeable with the most common slurry pump design in the mining industry.
• Bearing assembly- large diameter shaft with short overhang contributes to long bearing life.
• Liners – easily replaceable liners are bolted, not glued to the casing for positive maintenance.
• Casing – casing halves of cast or ductile iron provide high operating pressure capabilities.
• Impeller – front and rear shrouds have pump out vanes that reduce recirculation and seal contamination.
• Throat bush – wear is reduced and maintenance simplified by the use of tapered.

SEAL ARRANGEMENTS
Shaft sleeve
An easily removable shaft sleeve manufactured in either hardened or ceramic coated stainless with o-ring seals at both ends protects the shaft from abrasive or corrosive contaminants.
Hi-Seal
External gland sealing water is avoided in most applications by utilizing the “Hi-Seal” expeller design. Where flushing water is unavoidable, restricted flow glands keep this to a minimum.
Mechanical seal
Available for most applications, single or double mechanical seals can be offered as an alternative to a conventional seal.
