Mud Motors

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

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

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
