Description

The improved linear drive was introduced to reduce mechanical failures while maintaining a cost conscious alternative to existing balls screws. Unique design improvements machined to exacting standards provide field proven downhole reliability and reduced maintenance costs.

EETP’s robust plug-and-play design has increased reliability and longevity with an improved top bearing design and >3000 hr ball screw MTBF. Chromium Moly steel and hardened SS shafts combine with other design improvements to significantly reduce net operating costs.
