About this product
Product information from the supplier.
The Auxiliary Impeller is a critical sealing component specifically engineered for high-performance slurry pumps, designed to handle fluids containing abrasive impurities. By integrating a precise assembly of pressure relief covers, water seal rings, packing glands, and shaft sleeves, this component ensures optimal containment and protects the pump's internal mechanisms from premature wear and leakage.
Engineered for versatility and durability, our auxiliary impellers are available in multiple high-grade materials including cast iron, high chromium alloy, and resilient rubber to match your specific operational environment. Whether you are operating single-stage pumps or series-connected first-stage systems, these impellers provide a reliable sealing solution that eliminates the need for external shaft seal water and prevents pulp dilution.

Frequently Asked Questions
Q: What are the primary materials used for the auxiliary impeller?
The auxiliary impeller is typically manufactured from cast iron for standard use, while high chromium alloy and rubber are available for high-abrasion or corrosive applications.
Q: When should I use an auxiliary vane shaft seal instead of a standard seal?
It is recommended when the positive pressure at the pump inlet is not greater than 10% of the pump outlet pressure, particularly for single-stage or first-stage series pumps.
Q: Does the auxiliary impeller seal require external water cooling?
No, one of the key advantages of the auxiliary vane shaft seal is that it does not require shaft seal water, preventing the dilution of the pulp.
Q: What are the different structural forms of the auxiliary impeller seal?
There are two main structural forms: the metal decompression cover seal and the rubber decompression cover seal, with the metal version being the most common.
Q: Is the auxiliary impeller considered a wearing part?
Yes, because it handles slurry containing abrasive impurities, it is classified as a wearing part and should be inspected regularly for replacement.
Q: What is the main disadvantage of using an auxiliary impeller?
The primary disadvantage is that it generally results in higher power consumption compared to some alternative sealing methods.
