Keystone Hard Iron Sleeves

Hard Iron Shaft Sleeves

Keystone Pumps Hard Iron Shaft Sleeves provide exceptional wear resistance for pumps and rotating equipment.

What are the advantages of the Keystone Hard Iron Shaft Sleeves?

The Keystone Hard Iron Shaft Sleeves are manufactured from a specialized hardened cast iron material called High Chrome White Iron (ASTM A532 CLIII Type A).  The High Chrome material is abrasion resistant and hardened from the inside diameter to the outside diameter of the sleeve; 


Original equipment shaft sleeves are typically manufactured from carbon steel or are special ordered with a hardened coating that has a thin layer of hardened material.  The carbon steel sleeves tend to wear quickly on abrasive slurries causing premature packing failure.  Expensive shaft sleeves that have a thin layer of hardened coating can delaminate causing premature seal failure making the cost benefit of these sleeves not worth the investment.

Our Keystone Hard Iron Shaft Sleeves have longer and more consistent wear resistance capabilities as it is extremely hard throughout the entire shaft sleeve material.
