Slurry sand pump shaft seal assembly

Shaft seal of a centrifugal mine tailing slurry pump adopts many kinds of sealing systems: packing seal, expeller seal, mechanical seal and all sorts of special combined seals. Select applicable seal to improve service life and reduce economic losses.

Product Description

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

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

2. Bearing assembly parts

3. Shaft seal parts/Gland set: Sealing flexibility choice of gland, Expeller seal or mechanical seals.

1.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.

2. 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. For high abrasion conditions, The ceramic shaft sleeve is available.

3. Mechanical seal:

Good sealing performance, almost no leakage. It is suitable for transporting flammable, explosive, high-temperature and high-pressure liquids, making up for the lack of packing sealing.

Sand Gravel Pumps

Ultra strong coarse particle handling gravel pumps Zidong Pump® ZG(H) Series horizontal gravel pumps are single-casing pumps with wider passage channels, designed to convey media containing large particles. These pumps are engineered to continuously handle highly abrasive slurries with oversized solids that cannot be pumped by standard slurry pumps. The wet parts are constructed from Ni-Hard and high-chrome alloys, ensuring extended service life. They excel in applications such as dredging, sand mining, barge loading, and mineral processing.

Large Dredging Pumps

Customized high-efficiency dredging pumps ZN Series high-efficiency dredge pump is a newly designed single-suction, cantilever-style horizontal centrifugal pump. It is specifically engineered for dredging, land reclamation, and similar operations in rivers and lakes, meeting the rigorous requirements of industrial dredging equipment. The wet parts are constructed from 27% wear-resistant high-chrome alloy, offering advantages such as high head capacity, large flow rates, superior efficiency, and excellent NPSH performance. Capable of continuously discharging gravel, sludge, and other materials, this pump is ideal for applications including river channel maintenance, historical sediment recovery, and metallurgical explosive sludge treatment.

Hard Metal Alloy Liner Slurry Pumps

Heavy duty wear resistant mining tailing slurry pumps Zidong Pump® ZH Series heavy-duty slurry pump features wet parts constructed from 27% high-chrome alloy. This pump is engineered to handle highly abrasive, high-hardness, mildly corrosive, and high-concentration slurries while requiring minimal maintenance. It is widely applied in mining, coal processing, metallurgy, power plants, construction materials, and other industrial sectors. Depending on medium conditions, users can select specific material grades such as A05, A07, and A49.

Rubber Liner Slurry Pumps

Corrosion resistance mineral slurry pumps Zidong Pump ® ZHR series rubber liner slurry pumps have the features of replaceable corrosion-resistant rubber liners. They are ideal choice for conveying fine particles and corrosive slurries without sharp edge. A major advantage of the Zidong slurry pump is multi-optional materials, such as Natural rubber, Nitrile rubber, Polyurethane etc. This enable a pump to be constructed with the most appropriate materials specifically to meet the duty requirements. These wet parts can be mixed use for better performance, lower cost and longer lifetime.
