Mud Pump Liners

Mud pump liners are generally available in chrome, alumina ceramic and zirconia ceramic. While chrome liners and alumina ceramic liners are less expensive to purchase, their cost of ownership far exceeds the cost of ZIRCONIA CERAMIC LINERS. Following is a Cost of Ownership Analysis which shows a reasonable cost comparison for a rig in continuous service for three years. Numbers shown are cost per cylinder. Multiply the savings by the number of pump cylinders on your rig(s) to realize the cost savings available to you by using zirconia.
