Features

1. Modular design, easy to maintain,low spare cost due to high standardization;

2. Wide options of impellers of standard 5 vanes , open 3 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 rubber liner corrosion resistance mineral slurry pumps is mainly composed of 3 parts:

1.The anti-corrosion wet parts: (Impeller,Throatbush, Frame plate liner, Cover plate liner)Thickened wet components for extended wear life.

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

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 applys 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.
