CNSME Heavy Duty & Light Duty Slurry Pumps

AH(R) Heavy Duty Slurry Pump Range

CNSME’s AH(R) heavy duty slurry pumps are engineered for the continuous handling of highly abrasive and corrosive slurries.

• Robust Construction – Heavy-duty design with through-bolt assembly ensures structural integrity, easy maintenance, and minimal downtime.

• High-Efficiency Impellers – Large-diameter, slow-turning impellers maximize wear life, reduce operating costs, and improve efficiency.

• Bearing Assembly – Cartridge-style bearing unit allows service in a clean environment without removing the pump, delivering reliable operation and longer bearing life.

• Flexible Shaft Seal Options – Gland seal, expeller seal, and advanced “HS1 Hi-Seal” types are available to suit specific site requirements.

• Optional WRT Technology – Upgraded impeller and throatbush design improves efficiency, reduces NPSHr, and extends wear life.

Unique Advantages of CNSME Heavy-Duty Pumps

• Expeller Seal Assembly (“Dry Seal”) eliminates the need for flushing water.

• Interchangeable wet-end parts (metal or elastomer) lower overall maintenance costs.

• Designed to handle high concentrations of abrasive solids with reliable long-term performance.

L(R) Light Duty Slurry Pump Range

The CNSME L(R) series light-duty pumps are ideal for medium to lower head applications, offering the same design principles as the AH(R) pumps but at a more economical initial investment.

• Wide Hydraulic Coverage – Discharge sizes from 20mm to 650mm, including small 20mm models for laboratory or pilot use.

• Energy Efficient – Large, slow-turning impellers and open internal passages reduce slurry velocity, lower wear rates, and improve efficiency.

• Ease of Maintenance – Thick bolt-in liners (alloy or elastomer) provide corrosion resistance, quick replacement, and extended wear life.

• Stable Operation – Minimal shaft/impeller overhang reduces shaft deflection, increasing seal and packing service life.

• Seal Options – Standard gland seal (wet seal with clean flushing water), expeller seal, or HS1 type options available.
