Mechanical seal support systems are the lifeline to dual, liquid lubricated mechanical seals. By providing a dedicated lubrication system, mechanical seal performance will be optimized. Other less efficient systems will compromise seal performance and reliability goals. This high-capacity support tank is designed with versatility in mind. The Chesterton high-capacity tank provides 50% more liquid volume as compared to conventional tanks. Increased heat removal will provide a cooler seal environment. Lower operating temperatures mean greater reliability and reduced seal leakage rates. One tank can reliably satisfy a wide range of applications.
