X7718 Fits Rexnord Pump Shaft Seal - Carbon/Ceramic Direct-Fit Replacement Mechanical Seal

Is your Rexnord pump leaking where the shaft enters the pump? A worn shaft seal wastes water and lets moisture reach the motor - the most expensive part to replace.

This Beaver Island Parts Company replacement mechanical shaft seal for OEM part Rexnord X7718 is an exact-fit 3/4 in shaft seal engineered to restore your Rexnord equipment to leak-free service.

Full Compatibility: Rexnord X7718. Also replaces: 605, 607, 609, 5RP. 3/4 in shaft, 1.343 in OD head, 1.375 x.406 in cup-mounted seat.

Installation Note: Remove the pump's seal plate and impeller to access the seal - basic hand tools required. IMPORTANT: never lubricate or touch the polished ceramic and carbon seal faces - install them clean and dry; oils and fingerprints cause premature leaks.

Pro Tip: Apply Aqua Flex silicone lubricant to the rubber bellows and seat cup ONLY to ease installation - never on the seal faces. Aqua Flex lubricant is available in our store.
