The primary function of a liner is to regulate the flow and pressure of drilling fluid during piston operation. We manufacture both chrome-plated and ceramic liners. When paired with Kevlar pistons, ceramic liners can deliver maximum service life between maintenance intervals.
Our liners are compatible with the following pump brands: FMC, Aplex, KERR, Hengtan, and Prime Drilling.
Our signature color is orange — a visual mark that your liner was manufactured by BORG. When ordering directly from us, you receive an additional 6-month warranty on top of the standard coverage.
Guaranteed Compatibility
We guarantee that any liner purchased from BORG Pumps GmbH will fit your drilling pump perfectly. Choose reliability and precision — choose BORG Pumps GmbH!
