Bearing Bracket ASSEMBLY & Lubrication

Shaft DesignNS Series Shafts are designed with solid & Sleeved

3 4options to have low shaft stiffness ratio (L /D ) thus minimizing shaft deflection in turn promoting improved seal & bearing life. First Obstruction length (FOB) requirements of standard readily available single mechanical seals are considered in the design.

Type TB is single, outside mounted seal, uses PTFE bellows as secondary seal offering universal chemical resistance for a broad range of clean & corrosive pumping media.

Type RA is single, outside mounted seal, employs fluoroelastomer (FKM/FFKM) as secondary seal to handle highly corrosive & homogenous slurries.

Type GP is packed with resilient or semi-resilient material, provides a dynamic seal. Gland Packing is the most common and least expensive sealing for pump.
