Ev10 Metal Bellow Cartridge Seal
A factory assembled, pressure tested, rotary single metal bellows cartridge seal. This seal can handle a wide spectrum of applications from cryogenic to high temps. Bellows is self cleaning due to its rotation and is balanced for high pressures.
Features and Benefits
- EASY TO INSTALL – No measuring is required to install the Enviro 10 cartridge seal.
- NO SHAFT OR SLEEVE WEAR – There are no dynamic O’Rings on the shaft or sleeve to cause the fretting to equipment.
- ALIGNMENT BALANCE SHIFT – The balance automatically adjusts providing lower balance for low pressures that results in longer life, and high balance for high pressures that provides consistent low leakage performance.
- PRESSURE TESTED – All Enviro 10 seals are completely pressure tested at the factory to assure no inherent problems at the pump site.
- 3 WAY CLIPS – A new design clip not only centers the seal but stops axial movement in both directions.
