Sealing Functions

  • Both rotating & non-rotating seals
  • Seal drilling mud away from bearing lubricants
  • Provide required pressure balance
  • Critical to mud motor performance

Typical Seals

Mud Motor RM Seal
RM SEALS
– Fluid retention lips on the inside diameter which prevent the seal from spinning in the groove and reduce frictional heat
– Provide stable positioning for positive sealing at the outside diameter lip contact surface
– Activation slots which allow drilling mud to energize the sealing lip during pressure fluctuation

Mud Motor Type B PolyPak
TYPE B POLYPAKS®
– Increased stability: helps prevent the seal from spinning in the groove
– Allows grease in relief groove to migrate to the shaft and full pressure across the seal
– Allows storage of grease and reduces high squeeze contact forces
