摘要
A subsea mudlift pump includes a pressure sealed housing disposed in a body of water in which a wellbore is being drilled by a drilling rig disposed above the surface of the body of water. A motor (44) is configured to generate linear motion is coupled to at least one piston (46) disposed within the housing such that operation of the motor causes linear motion of the piston within the housing. One side of the piston is within a pumped fluid chamber that changes volume when the piston is moved within the housing.
