Excessive radial clearances designed in the seal make it ideal for vertical turbine pumps in power plants, pulp & paper mills, municipalities, and applications in relatively clean, lubricating fluids. OPERATING CAPABILITIES: Pressures: Up to 300 psig Up to 400° F, 205° C 5000 fpm 316 SS Stationary Ring: Secondary Seals: High quality chemical grade carbon-graphite, solid nickel bound tungsten carbide, silicon carbide, and high purity ceramic 17-4PH stainless steel. Viton, EPR and Aflas Cartridge Mounted The VSR is a completely self contained unit that is pre-assembled and pre-set at the factory for ease of installation. This feature also allows impeller adjustments to be made quickly and easily without interfering with the correct axial setting of the seal. Mounts Externally This allows installation on equipment where packing has been used without having to replace expensive shafts and sleeves. Hydraulically Balanced Hydraulic balancing is achieved internally allowing operation in higher pressures without the need for special stepped sleeves and shafts. Balancing also provides cooler operation and extended reliability. Versatile Gland The gland is vented to eliminate air entrapment and improve cooling efficiency for longer seal life. Machined glands offer superior corrosion resistance and strength and can be modified to fit the equipment. Fully Repairable All sealing elements that wear during normal operation can be replaced and the seal repaired at a fraction of the cost of a new seal while providing performance consistent with a new seal.
