Heavy Duty Wear Resistant Mining Tailing Slurry Pumps

ZH series Slurry Pumps are single-stage, single-suction and cantilevered, double casing, horizontal, centrifugal, heavy duty durable design. Parts in contacting with the medium are made of latest wear-resistance 27% chrome alloy white iron with hardness 62HRC over, which has an highly abrasive for maximum resistance to strong abrasive, coarse particle.

2. Wide options of impellers of standard 5 vanes, 4 vanes high efficiency and 2 vanes non-clogging;

3. 27% Chrome alloy hard metal, thick rubber and polyurethane pump lining are available and can be replaced with each other;

4. Standard ductile iron pump body, can withstand higher working pressure;

5. Famous brand bearing components can improve reliability, prolong bearing life and reduce lubrication cost;

6. Reliable shaft seal, packing seal, expeller seal, or mechanical seal are available;

7. Multi purpose design reduces inventory requirements and interchangeability;

8. Drive types: Different connection methods (ZVZ,DC,CV,CRZ) with motor for selection, satisfy the requirements on different installation condition and different capacity & head.

9. The discharge direction of the pump can be oriented to any 8 positions based on different installation condition.

Structure Features

A centrifugal heavy duty alloy liner mine tailing slurry pump is mainly composed of 3 parts:

1. The anti-abrasion wet parts: (Impeller, Throatbush, Volute liner, FPL insert) Thickened wet pats for extended wear life.

2. Shaft seal parts: Sealing flexibility choice of gland seal, expeller seal or mechanical seal.

3. Bearing assembly parts

Expeller Seal Assy: Expeller seal is an impeller force of reversed centrifugal force preventing slurry leakage. Expeller seal can be on the single stage pump when the positive pressure of pump inlet is no more than 10% of pump outlet pressure or on the first-stage pump in the pump series.

Gland Seal Assy: Packing Seal is a general shaft seal. It apply to various pumping conditions, PTFE and Graphite materials of Packing can be used in high corrosive slurries or high temperature conditions. It has the advantages of simple structure and convenient maintenance. But need to add shaft seal water, and should ensure enough water pressure and water yield.

Mechanical Seal Assy: Mechanical Seal is advanced sealing technique without sealing leakage, integrating construction, convenient installation & replacement, various constructions suit for all kinds of conditions.

Bearing assembly advantage features: 

1. A large diameter shaft with short overhang minimizes deflection and contributes to long bearing life.

2. Four through bolts are required to hold the cartridge type housing in the frame. 

3. The removable cartridge-type bearing assembly facilitates easy on-site maintenance procedures. 

4. Provided with hardened shaft sleeve to protect the shaft .

5. Grease purged piston rings to help seal contaminates out of bearing housing. 

Applications

The ZH centrifugal heavy duty alloy liner mine tailing slurry pump is the pump for highly abrasive/density slurries in processes from cyclone feed to regrind, mill discharge, flotation, mine drainage and tailing in minerals plants plus other industrial applications, Sometimes, it could also be used in dredging of settling lagoons and pumping of drilling mud etc.
