Durable V-Packings are lubricated and cooled by the liquid being pumped. Pre-set Lo-Pressure Seals provide secondary protection against external leaks and require no packing adjustment. Special high-density, polished, concentric plungers provide a true wear surface and extended seal life. Special ported manifold (Model 661C) permits an external flush liquid providing cooling for hi-temp liquids and lubrication for low lubricity liquids.
