Product Description Type 5840
ype 5840 is a cartridge seal design, suitable for abrasive slurry duties and capable of operating without a quench. A modular construction incorporates a cone spring which avoids clogging and eliminates the dynamic O-ring and risk of hang-up. Seal faces are silicon or tungsten carbide and identical. Adaptive hardware is alloyed stainless steel or high chrome iron to provide both excellent corrosion and abrasive resistance of wetted components. A quench seal option available of improve service life
