World's first all-metal progressing cavity pump

Positive displacement pump specialist PCM has developed what is reportedly the world's first all-metal progressing cavity pump. The PCM Vulcain pump is capable of pumping extremely hot (350°C/660°F) and extremely viscous fluids.  

"Standard progressing cavity pumps (PCP), sucker rod pumps (SRP) and electrical submersible pumps (ESP) are limited in terms of maximum operating temperature. In contrast, the PCM Vulcain is the only pump that works efficiently at the high temperatures of thermal recovery," says Nicolas Parise, Director, PCM Oil & Gas Business Unit. "Elastomer stators make standard progressing cavity pumps unsuitable for use at extremely hot temperature - and other existing pump technologies are not as inherently efficient or reliable as progressing cavity pumps."

The pump outperforms outperforms beam pumps in overall system efficiency and it is less fragile than electric submersible pumps. It is also energy-efficient and has lower capital expenditure than comparable submersible and rod pumps.
