EV10 Cartridge Seal

EV10 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.
