  • Description

    A carbon stator is connected to the rubber below and 'floats' around the shaft. The face of the carbon is finished to a flatness of 4 helium light bands and provides a water-tight seal when pressed against the stainless steel rotor.

    The high density, resin impregnated carbon/graphite stator is a space-age composite that is first mixed, molded, and then formed under pressure. The blanks are then baked, machined, and lapped. The face of our carbon is finished to a flatness of 4 helium light bands (measured .000044" of variation over the entire lapped surface). The grade of carbon used in the PSS has an operating temperature of over 500° Fahrenheit (+260° Celsius), and cannot melt if the seal runs dry, unlike a rubber lip seal or plastic face seal. The high density of the carbon greatly increases the longevity and wear resistance. Several commercial vessels have recorded over 40,000 (over 4-1/2 years of continuous operation) engine hours on the same, original components. The carbon should not need to be replaced under normal operating conditions.

Carbon Stator

The part was exactly what I needed. These guys went above above and beyond when it came to customer service. I was unsure when the part would ship and I was under a time crunch to get it installed. I contacted PYI to see when it would ship and arrive. There customer service guys (Eric and Eric) checked and informed me it had already shipped and gave me a date it should arrive. I got the part as promised, it was exactly what I needed and I was able to get it installed ahead of schedule. I will definitely be purchasing from them in future!
