PivotAL Progressing Cavity Pumps

Product Overview

The PivotAL PCP rotor has alternating 12” long sections of varying profile dimensions that supplement the conventional rotor’s continuous interference fit with clearance sections. These clearance sections result in the associated stator sections not experiencing damage during normal operation thus allowing subsequent rotor repositioning of an interference section into these areas to restore pump performance.

Challenge

When well conditions produce burnt, chunked, fluid-washed, or worn stator failure modes, there is significant damage to the stator sections that require costly well intervention and replacement of the stator.

Solution

The PivotAL has proven performance to combat this challenge in low inflow, gassy, sandy, and abrasive conditions.

With the PivotAL PCP, the alternating rotor dimensional sections allow for clearance. When the interference pumping sections start to wear or suffer other damage, the pump can be quickly restored by lifting the rotor up 12” above the original installed position using a flushby or the Lifting Solutions Endless Rod Unit (ERU). This moves the interference fit sections of the rotor out of the damaged sections of the stator and into the undamaged sections restoring performance.
