• 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.
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.

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 35mm seals for our main transfer lines. Availability is great and they last just as long as the originals.

FAQs about Metal Bellows Seals for High Temperature Pumps
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.
