Advantages
Pillar seal is widely used for big sea ship pump, In order to prevent corrosion by sea water, it is furnished with mating face of plasma flame fusible ceramics. so it is a marine pump seal with ceramic coated layer on the seal face, offer more resistance against sea water.
It can be used in reciprocating and rotary movement and can adapt to most fluids and chemicals. Low friction coefficient, no crawling under precise control, good anti-corrosion capability and good dimensional stability. It can withstand rapid temperature changes.
Suitable Pumps
Naniwa Pump, Shinko Pump, Teiko Kikai, Shin Shin for BLR Circ water, SW Pump and many other applications.
