Guideline Centrifugal Pump Selection and Piping Design For Mud System

The purpose of this article is to present some guidelines and simplified techniques to size pumps and piping typically used in mud systems. If unusual circumstances exist such as unusually long or complicated pipe runs or if very heavy or viscous drilling muds are used, a qualified engineer should analyze the system in detail and calculate an exact solution.

CASING OF CENTRIFUGAL PUMP

The function of the centrifugal pump casing is to:

  • Direct fluid into the eye of the impeller through the suction inlet.
  • Minimize fluid recirculation from impeller discharge to impeller suction.
  • Capture fluid discharge from the impeller in the case volute to most efficiently utilize work performed by the impeller and direct fluid away from the impeller. (See Picture 1. and 2.)
