EVEN WALL

Improve temperature distribution and mitigate swelling

Better control temperature distribution in progressing cavity pumps (PCPs) with the EVEN WALL uniform-elastomer PCP. In a conventional progressing cavity pump, the heat accumulates where the elastomer is thicker and can potentially damage the elastomer. The EVEN WALL PCP incorporates uniform elastomer thickness, resulting in an even temperature distribution.

The PCP works particularly well under swell conditions. Uniform swelling of the elastomer enables an accurate, more consistent fit between the rotor and stator, improving pump performance and making this technology suitable for light oil applications, wells with high temperatures, or wherever swelling is likely.
