multiphase pump

1. n. [Production Facilities]
A pump that can handle the complete production from a well (oil, natural gas, water and sand, for example) without needing to separate or process the production stream near or at the wellhead. This reduces the cost associated with the surface facilities. Using multiphase pumps allows development of remote locations or previously uneconomical fields. Additionally, since the surface equipment, including separators, heater-treaters, dehydrators and pipes, is reduced, the impact on the environment is also reduced. Multiphase pumps can handle high gas volumes as well as the slugging and different flow regimes associated with multiphase production. Multiphase pumps include twin-screw pumps, piston pumps and helicoaxial pumps.
