Literature Offered On Cartridge-Mounted Seal For Viking Pumps

Cartridge-mounted Style 114 Chesterton® Seal from A.W. Chesterton Co., Stoneham, Mass., is expressly designed to convert several series and models of Viking Pumps from mechanical packing to mechanical sealing.

Conversion is easily accomplished by removing the original pump packing and gland. The only modification needed is to machine a counterbore in the stuffing box face 2'Xe inches O.D. by Vs-inch deep. On sliding the 114 Seal on the shaft, the counterbore mates with the gland pilot and locates the seal onto the shaft at the proper position. No measuring, centering or adjusting of the 114 Seal is needed.

Conversion to sealing eliminates packing leakage and maintenance adjustments. Better control of slurry fluids is attained with a dynamic 0-ring located at the back of carbon holder, minimizing buildup of particles and possible clogging of seal. A static O-ring eliminates any grooving or fretting of shaft. A circulating line port is included in gland for flush applications. All parts are precision set in gland as single cartridge unit. There are no loose components to be mislaid or inaccurately installed.
