Excellent corrosion resistance
We use these in agricultural irrigation systems where water quality varies. The copper alloy holds up remarkably well against corrosion compared to previous brass alternatives we tried.

Perfect fit for my QJ pump
These copper sleeves fit perfectly into my submersible pump rotor. The machining quality is excellent, and the copper alloy feels very durable. Installation was straightforward.

Restored old pump to life
My 10-year-old pump was making noise due to worn bearings. Replacing the bushings with these copper sleeves silenced it completely. Great product for maintenance.

Solid construction
The weight and finish of these sleeves indicate good material quality. They fit the QS series specs accurately. Only minor issue was shipping took a bit longer than expected.

Good quality replacement parts
Bought these to replace worn-out bushings in an older deep well pump. They seem to be made of high-quality copper and have restored the pump's efficiency. Slightly pricey but worth it.

Professional grade accessories
As a pump technician, I recommend these copper bushings for any QJ submersible pump repair. They provide smooth operation and reduce friction effectively.
Q: Do I need special tools to install these bushings?
A: Standard mechanical press tools or appropriate sizing mandrels are recommended for installation to ensure the bushings are seated evenly without damaging the copper surface.
Q: What is the advantage of copper alloy over standard brass?
A: Copper alloy offers superior thermal conductivity and better resistance to wear and corrosion in water environments, leading to a longer lifespan for your pump components compared to standard brass.
Q: Are these sleeves compatible with all QJ series pumps?
A: These sleeves are designed specifically for standard QS and QJ submersible pump models. Please verify your specific pump model number against our size chart before purchasing to ensure a perfect fit.
Q: Can these be used in saltwater applications?
A: While the copper alloy has good corrosion resistance, it is primarily designed for fresh water deep well applications. For high-salinity environments, we recommend consulting with our engineering team for specific material advice.
Q: How many sleeves come in one package?
A: Each package contains a complete set of copper sleeves required for a standard rotor assembly replacement. Please check the product description for the exact count based on your pump stage configuration.
