This high-performance APV pump mechanical seal is engineered as a direct OEM replacement for SPX APV W+, V2, and World series pumps. Designed for sanitary applications, it provides a reliable, leak-free solution for food, dairy, and beverage processing.
Key Features
• Metric Standard Fit: Specifically engineered for the 30mm, 32mm, and 35mm shaft variants of APV W+ and V2 series pumps.
• Modular Face Options: Available with Carbon, Silicon Carbide, or Tungsten Carbide faces to match your specific process fluid (water, milk, or abrasive slurry).
• Simplified Inventory: One seal design covers multiple pump models sharing the same shaft diameter, reducing stockholding requirements.
• Optimized Drive: The drive mechanism is designed to engage securely with the APV shaft drive pin or keyway, preventing slippage.
• Dynamic O-Ring Groove: The O-ring groove geometry is optimized to prevent O-ring rolling or extrusion during CIP pressure spikes.
We specialize in tailoring this APV pump Mechanical Seal to your specific pump model and process requirements.
Size-Specific Solutions: We stock the mechanical seal 30mm, mechanical seal 32mm, and mechanical seal 35mm sizes for common APV models. Provide your pump serial number for exact cross-reference.
Material Configuration: Customize the APV pump mechanical seal face materials (e.g., Tungsten Carbide for extreme abrasives) and elastomers (EPDM, FKM/Viton) to match your fluid and temperature needs.
Lead Time: Standard mechanical seal 30mm and mechanical seal 35mm sizes are available from stock. Custom mechanical seal 32mm configurations typically have a short lead time.

Case Study
Beer Brewing: A brewery used 35mm APV pumps for wort transfer. Grain husks caused standard carbon seals to leak. We switched them to our 35mm SiC/SiC replacement. The hard faces crushed the particles, solving the leakage issue.
Testimonials
We rely on these 30mm 32mm 35mm mechanical seals for our main transfer lines. Availability is great and they last just as long as the originals.

FAQs
Q: How do I measure the size?
A: Measure the pump shaft diameter where the seal sits. It will be exactly 30mm, 32mm, or 35mm. Do not measure the rubber bellow ID as it is smaller before installation.
Q: Is this APV pump mechanical seal a direct replacement for my APV W+ pump?
A: Yes. Our APV pump mechanical seal is designed as a direct OEM replacement. The mechanical seal 30mm and mechanical seal 35mm sizes are particularly common in W+ and V2 series pumps and are available from stock.
Q: What is the difference between the 30mm, 32mm, and 35mm sizes?
A: The size refers to the inner diameter (shaft size) of the APV pump mechanical seal. The mechanical seal 30mm and mechanical seal 35mm are the most prevalent. The mechanical seal 32mm is less common but available for specific APV models. Provide your pump model for the correct size.
