2 MAH HORIZONTAL SLURRY PUMPS Heavy duty, horizontal slurry pumps. High efficiency transfer of abraisive and high density slurries with extended wear life and reliable service intervals. VERSATILE HEAVY DUTY SOLUTION Milestone MAH series pumps are heavy duty horizontal slurry pumps designed to handle the transfer of abraisive and high density slurries in mining and heavy industry. 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. Pumps are available in sizes ranging from 1 inch (25mm) to 18 inch (45mm) discharge and feature high efficiency performance capable of flow rates from 1.8 to 65 m 3 /hour (48-286USGPM) and heads up to 125 metres (41ft) for high head models. All Milestone MAH slurry pumps are designed to be interchangeable with the most common slurry pump footprints used by the mining industry. MAH pumps are manufactured using the highest quality materials to ensure reliability and extended service life in heavy duty applications. MAH pumps are manufactured with a rugged cast iron outer casing which features reinforcing ribs for excellent high pressure strength and safety. WEAR LINERS A range of replaceable wear liners are available in 27% chrome white iron, rubber or urethane to suit the requirements of specific applications and slurry types. Wear liners are easily replaced when required by simply removing the front cover plate bolts and sliding off the front cover. This allows minimal downtime and simple servicing for maintenance staff. IMPELLERS The impeller features pumpout vanes on the rear face to prevent recirculation. s are available in 27% chrome white iron or rubber to suit the requirements of the pumped product and are easily accessible by simply removing the front cover plate bolts and sliding off the front cover. EXTERNAL IMPELLER ADJUSTMENT An external impeller adjustment bolt is located under the bearing assembly and is easily accessible. This allows for changes to be made to the impeller clearance to maximise efficiency and service life without removing the front cover plate or disconnecting pipework or the bearing assembly. The system allows quick and simple adjustments to be made to compensate for wear and changes in operating conditions and duty points. MILESTONE MAH 2x1.5B HORIZONTAL SLURRY PUMP MILESONE 4x3EHH 2

3 MAH pumps are fitted with heavy duty bearing assemblies with angular contact bearings in the wet end and single or double row deep groove roller bearings in the drive end. s are grease lubricated as standard and are available with the option of oil lubrication to meet customer requirements. assemblies are fitted to the bearing frame with four through bolts allowing for quick removal and simple servicing. SHAFT SEALING OPTIONS Pumps are fitted with packed gland type shaft seals as standard with PTFE packing and pumped product lubrication. Optional external clean water lubrication is available as an option to suit applications where product lubrication is not viable. MECHANICAL SEAL A range of mechanical seals are available to replace the packed gland shaft seal. Adaptor plates can be easily fitted to match the requirements of specific types of mechanical seals and seals are available in a wide range of materials. EXPELLER MAH pumps are fitted with an expeller as standard which reduces seal face pressure and reduces recirculation to extend seal life and reduce impeller wear. 1% INTERCHANGEABLE All MAH spare parts are fully interchangeable with the most common slurry pump design in the mining industry. High quality Milestone spare parts can be fitted into existing pumps to improve performance and extend service life.
