ZM(R) series middle duty sludge and slurry pump are single-stage, single-suction, cantilever, double casing and horizontal centrifugal slurry pump, applying to large flow, low concentration and lower head operating conditions. Under low speed, ZM type slurry pump can transmit strong abrasion and high density slurry. When compared with WX type slurry pump of equivalent diameter, ZM type is smaller, lighter and higher in cost performance, being widely used in metallurgy, electric power, chemical industry, mining, papermaking, building materials and other industries.

For details see clear water performance table on the bottom.

Structural features
1. With large diameter and short cantilever, the rigidity of the shaft is ensured to make the pump applicable to high power and severe operating conditions.

2. The hardened stainless shaft sleeve and the shaft is cooperated by clearance fit and the both ends equip O-ring to prohibit the shaft from abrasion and corrosion.

3. Both the front and back cover board of the impeller are equipped with auxiliary blade to reduce return flow and the sealing pressure. The impeller also uses wide-runner, blade concave and other methods to improve the ability of conveyance and anti-abrasion for extending its service life.

4. The pump casing and cover adopt ductile iron, coupled with strengthening rib, to ensure the ability of withstanding high pressure.

5. The overcurrent parts that are made by various high Cr anti-abrasive alloys or rubber of different performance, have features of anti-abrasive, anti-corrosion, impact resistance, scouring resistance, etc. The metal overcurrent component and the rubber one can be used interchangeably or in mixed way to satisfy the need of different operating conditions.

6. We provide packing seal, auxiliary impeller seal, mechanical seal and other seal types for shaft seal to meet the need of different operating conditions.

7. The position of the pump outlet can be installed by rotating 8 different angles (with an interval of 45 degrees) according to the need.

8. Oil lubrication and grease lubrication are supplied for the bearing assemblies. The oil lubrication components can effectively lower the operation temperature to reduce the trouble caused by the too high bearing temperature. The grease lubrication components are of simple structure, reliable operation, and easy installing, commissioning and maintenance.
