5 Seal Options pable of carrying high ads to run beyond standard 5 hrs) Single PTFE Bellows seal (TB) Sleek, sturdy, low weight bearing bracket Gland Packing (GP) Single Pusher Seal (RA) 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. Operating parameters Type TB* RA* GP Pressure 5 bar (75 psi) 27.6 bar ( psi) 1 bar (15 psi) Temperature 71 C (16 F) 2 C ( F) 3 C (572 F) Shaft Speed 1 m/s (33 fps) 23 m/s (75 fps) 1 m/s (33 fps) *Values for Flowserve seals. Other seals available on request. Bearing Bracket ASSEMBLY & Lubrication st shaft with low stiffness o ensure less than.5 mm 2 in) deflection at seal faces maximizes mechanical seal mically optimized, closed / radial impeller designed for suction behaviour with low quirement e and vibration STANDARD Optional (with handle) Bearing Bracket Assembly Features High interchangeability between models thus lowering inventory. Rugged design minimizes unexpected downtime and enhances ease of assembly and maintenance. Lubrication Grease lubricated bearing bracket for applications C / 25 F uses grease nipples fitted at the pump end and drive end. Greased for life / Sealed for life bearings available on request. Shaft Design Impeller Options n of closed and semi-open with efficient blade passage for e pumping of process media Shafts are designed with solid & Sleeved options to have low shaft stiffness ratio (L3/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.
