The FDP8 is constructed from heavy-density open-cell polyurethane foam with a high-grade abrasion and chemical resistant polyurethane elastomer coating. The multiple sealing discs make it an excellent pig for regular wiping, batching, dewatering and product removal. Options include bare (no coating); dual-diameter configuration; pulling rope or cable; transmitter or pinger cavity; magnets; customized diameters and lengths for special pigging applications.
