Key Features

• Direct AES Replacement: A precise aftermarket equivalent for the AES W01 (Imperial/Inch) and W02 (Metric/DIN) elastomeric bellow seals.

• Non-Clogging Bellow: The smooth, full-convolution rubber bellow protects the shaft and spring from debris, preventing clogging in wastewater or slurry applications.

• Torque Drive: The bellow friction-drives the rotary face, eliminating the need for drive screws that can damage the shaft or fret the sleeve.

• Self-Aligning: The flexible elastomer bellow automatically compensates for shaft misalignment and end-play, ensuring consistent face contact even on worn equipment.

• Bi-Directional: The single coil spring friction drive allows the seal to operate in either clockwise or counter-clockwise rotation, simplifying inventory.

FAQs

Q: What is the difference between W01 and W02?

A: The W01 is designed for Imperial (Inch) shaft sizes and standard ANSI stuffing boxes. The W02 is designed for Metric (Millimeter) shafts and conforms to DIN 24960 (L1k) dimensions.

Q: Is this seal a 100% exact replacement for my existing AESSEAL W01 or W02 seal?

A: Yes. The MIAOYU AES W01/W02 Replacement Seal is engineered to be dimensionally and functionally identical to the original AESSEAL® W01 and W02 cartridge seals. It shares the same installation dimensions, shaft/sleeve sizes, and face materials, allowing for a direct, drop-in replacement with no modifications required. Always verify the specific elastomer material (EPDM/FKM) is compatible with your fluid.

Q: What are the main advantages of the elastomeric bellows design in this seal?

A: The elastomeric bellows design offers two key advantages over traditional pusher seals with multiple springs:

Solids Handling: The smooth, one-piece bellows has no small gaps or cavities for solids to accumulate and clog, preventing hang-up and spring failure—ideal for light slurries or fluids that crystallize.

Simplified Construction & Reliability: It eliminates the multiple small springs of a pusher seal, reducing the number of parts that can fail. The single, large-diameter spring provides consistent loading, and the bellows acts as a secondary sealing element.
