The APV Agitator 1" (25.4mm) mechanical seal, often identified by part references like the S66 series, is a heavy-duty sealing solution specifically designed for the rotating shafts of industrial mixers and agitators
Unlike standard pump seals, these are engineered to handle the unique axial and radial loads generated during the mixing of heavy or viscous fluids in large tanks.
Seal Description
- Precision Fit: Specifically designed for a 1-inch (25.4mm) shaft, ensuring a tight, leak-proof interface between the rotating agitator shaft and the vessel housing.
- Dual-Face Design: Typically consists of a stationary part fixed to the housing and a rotating part that follows the shaft, creating a dynamic seal.
- Material Durability: Usually constructed with high-grade faces like Silicon Carbide (SiC) or Carbon, and paired with elastomers such as EPDM or Viton for broad chemical and temperature resistance.
- Sanitary Build: Smooth surfaces and crevice-free designs support hygiene and ease of cleaning, often meeting FDA/sanitary standards for food and pharma use.
Best For
- Leak-Proof Mixing: Ideal for chemical and pharmaceutical reactors where preventing the escape of hazardous or expensive process fluids is critical.
- Dairy & Food Production: Best for use in large blending vats for creams, sauces, or yogurt, where high hygiene (CIP/SIP capability) is required.
- Abrasive Slurries: When configured with Silicon Carbide faces, these seals excel at handling liquids with high solids content without excessive wear.
- High-Torque Environments: Purpose-built to endure the mechanical stress and shaft "wobble" common in large-scale agitation.
