Elastomer Lined Centrifugal Slurry Pumps for Heavy Duty Corrosive Applications
Introduction:
We offer the most complete line of products for the mining industry, including slurry, process pumps, monitoring and control, and a full range of aftermarket and repair services. Due to our extensive portfolio for the mining industry, we can provide the right pump for our customers' application, thus maximizing reliability.
As an alternative to Hard metal lined A05 (HIGH CHROME ALLOY) slurry pumps, rubber pumps can also use for applications where pH value is high, but the solids are fine. Rubber elastomer is more suited to resist the abrasion from fine solids. The advantages of a rubber slurry pump over metal one are lower cost and lighter weight.
Rubber Lined slurry pumps are designed for corrosive, high-density slurries in the metallurgical, mining, coal, power, building material, and other industrial departments, etc. The pumps of this type also can be installed in multistage series.
1. Shaft Sleeve:
A hardened, heavy-duty corrosion-resistant sleeve with O ring seals at both ends protects the shaft. A slip-fit allows the sleeve to be removed or installed quickly.
Shaft Sleeve D075 is available in various materials, such as C21, C23, J04, J05, J32.
2. Gland Shaft Seal:
A packed gland type shaft seal is also available and can be fitted with a low flow or a full flow flush seal water arrangement.
Stuffing Box is available in materials G01, D21 and A05.
3. Centrifugal Shaft Seal:
A large percentage of duties allow the use of the WAR-MAN centrifugal seal which eliminates the need for sealing water.
Expeller and Expeller Ring are available in materials G01, A05 and A49.
Typical Applications:
Tailings
Heavy Mining
Ash Handling
Cyclone Feeds
Pulp and Paper
Corrosive Slurries
Coal Preparation
Mineral Processing
Aggregate Processing
Heavy Refusal Removal
