Minimum recommended shaft hardness is 250 BHN, and maximum operating temperatures are in the 450-500 F range. At the opposite end of the spectrum are aluminum and manganese bronzes, best known for their wear resistance and heavy load carrying ability. Both aluminum and manganese bronze possess excellent corrosion resistance, require good lubrication and recommended shaft hardness in the 400-600 BHN range. Maximum operating temperatures range from 400 F for manganese bronze to 750 F for aluminum bronze. SSiC of the EKasic materials family and customized product design offer improved, reliable performance in harsh and corrosive environments, and demanding applications in sealed and sealless pumps.
Any liquid can be a lubricant, and marginal lubrication can be tolerated.
ESK supplies sliding bearings, axial bearings and pump shafts for a variety of applications using canned motor, mag-drive, gear and screw pumps. Poor shaft support, dry starts, high friction and rapid wear in abrasive services are some of the more common problems. It also has the potential for contamination of the medium being pumped. Originally developed more than 25 years ago as a high performance pump bearing, Thordon is an elastomeric polymer alloy that provides exceptional wear life. Available in three grades, Thordon offers excellent abrasion resistance, low friction, superior load bearing capability and the ability to operate in water or oil lubrication.
