SPS-625 – External Mount Heavy-Duty Slurry Seal

Design Features

• Wear-Resistant Components: Sleeve end cap and gland insert can be manufactured from a range of wear-resistant materials tailored for slurry duty.
• Fully Outboard Mounted: Ideal for equipment with limited seal chamber space, ensuring improved reliability in challenging slurry applications.
• Large Port Orifices: 1/2″ NPT Barrier Fluid In (BI) and Barrier Fluid Out (BO) connections support Plan 53 or 52 configurations.
• Directed Barrier Flow: Internal deflector in the gland guides fluid to inboard faces. Outboard outlet placement enables efficient heat removal on both seal faces.
• Vortex Breaker Design: Gland insert features integral vortex breakers to manage solids in slurry or particle-laden process media.
• API682-Compliant Clearances: Ensures proper radial spacing between rotating and stationary elements.
• Monolithic Seal Faces: Enhanced high-temperature performance.
• Self-Aligning Stationary Face: Ensures stability and performance at high shaft speeds.
• Multi-Spring Construction: Springs are isolated from the process fluid to prevent fouling and wear.
• Efficient Pumping Ring: Bi-directional pumping for reliable barrier fluid circulation.
• Plan 53 System Compatibility: Designed for seamless use with HydroMax Seal Plan 53, 53A, 53B, and 53C systems.
