APV W+ Single Mechanical Seals
- The Ultimate Front-Loading Design: Features the patented APV internal arrangement where the seal faces reside directly behind the impeller .This permits rapid seal replacement from the front cover without disconnecting the pump casing.
- Best For: Low-viscosity, non-crystallizing food and chemical media, including milk, purified water, juices, beer, and aseptic solutions.
- Standard Material Pairings: Balanced Carbon vs. Silicon Carbide (SiC) or Silicon Carbide vs. Silicon Carbide faces paired with high-performance EPDM or Viton (FKM) O-rings. [1]
APV W+ Double (Flushed & Aseptic) Mechanical Seals
- Engineered for Severe-Duty Applications: Ideal for setups requiring a secondary liquid barrier or a clean steam flush. The dual-face configuration prevents high-temperature scaling and isolates your process fluids from the external atmosphere.
- Best For: Highly abrasive slurries, hot sugar syrups, chocolate, pharmaceuticals, and ultra-strict aseptic processing systems.
- Maximum Lifecycle Protection: Prevents face sticking and burning by continuously running an internal cooling barrier.
Eliminate operational downtime and seal leaks immediately.
