Polyurethane Bonded Pistons

Whitefield Plastics introduced the first bonded on steel dual durometer mud pump piston in the mid-1980s. Over the intervening 30+ years, there has been continuous improvement in chemistry, processes, and design, which has resulted in the ability to produce pistons ranging from the traditional dual durometer piston to single durometer high-temperature high-pressure pistons. Recent improvements include new piston geometry and the integration of high abrasion resistant materials into all piston styles.

• Traditional dual durometer piston (180 – 200F)
• High temperature & high-pressure pistons (280F and 7000+ PSI)
• Bluntnose/bullnose dual durometer pistons
• Single durometer traditional pistons

• Piston Geometry - Our extensive field testing allows us to identify unique properties and improvements to manufacture a higher-performing part
• High abrasion-resistant materials - We use the latest technology
• High pressure resistant materials
• Temperature/Material processes
• Up to 300 degrees F
• 7000PSI fluid ends

Proprietary chemistry advancements allow us to address abrasion, hysteresis, and mud chemistry issues.

• Our chemistry & processing advances allow us to fight abrasion
• Continuously improve designs & chemistry modifications to work against hysteresis
• We have a wide array of chemistry options to solve mud chemistry issues
