 NUTECH 3 MECHANICAL SEAL

Features and Benefits

  • EASY TO INSTALL - No measuring is required to install the NUTECH III cartridge seal.

  • NO SHAFT OR SLEEVE WEAR - There are no dynamic "O" rings on the shaft to cause fretting to your equipment and the seal is designed so that all wear parts are disposable.

  • ALIGNMENT - Stationary seats are resiliently mounted on an "O" ring and allowed to float for maximum face squareness.

  • IMPELLER ADJUSTMENT PUMPS - The NUTECH III can be installed on pumps requiring an impeller adjustment after the seal is installed. Adjustments can be made without removing the seal or dismantling the pump.

  • NO MODIFICATION TO EQUIPMENT - The NUTECH III low profile seal fits all ANSI pumps without modification and is superior in dimensional specifications to any other single cartridge seal commercially available.

  • API - Given pump information the NUTECH III can be manufactured to meet the American Petroleum Institute specifications for many petrochemical services.

  • 3 WAY CLIPS - A clip design that not only centers seal but stops axial movement in both directions.

  • "OFF THE SHELF" AVAILABILITY - The NUTECH III seal is available in 1.00" to 3 3/4". Larger shaft diameters are available on request.

  • PRESSURE TESTED - All NUTECH III seals are pressure tested before leaving our factory.
