A factory assembled, pressure tested, double cartridge seal suitable for pumps, agitators and mixers. Utilizes a barrier fluid to prevent leakage of toxic, hazardous and corrosive fluids to atmosphere.
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.
