Product details
-
The 40924A Series provides reliability, safety and efficiency. A double mechanical dynamic shaft seal located between the bearings ensures minimum possible shaft run-out, with a pressurized barrier fluid system and O-ring type static seals is used to achieve the highest level of safety. Reliability is ensured by slow speed operation and low differential pressures, which maximize bearing and seal life. The internal gear pump technology provides a more efficient solution compared to centrifugal pumps.
Features and Benefits:
Pressurized oil reservoir ensures barrier between inboard and outboard seals
Sight glass enables easy verification of oil level
Return-to-tank pressure relief valve prevents overpressure
Static o-ring seals between casing, head and bracket provide superior joint sealing.
Double mechanical seal with oil barrier for maximum safety
Lubricated idler bushing with pressure lubrication system (K, KK, LQ, LL sizes) provides constant film of liquid between idler pin and bushing for long life, regardless of pump rotation
Rigid, one-piece cast iron bracket with seal between bearings helps prevent misalignment to ensure long seal life
Rotatable bearing housing simplified end clearance adjustment
