The Type 37FSB fully split mechanical seal helps significantly reduce maintenance on larger, difficult-to-seal equipment. It is recommended for use on heavy-duty packed equipment that previously could not accommodate mechanical seals due to severe shaft runout and vibration, difficult disassembly, worn-out equipment and similar problems. Its outside-mounted design allows it to be used on both vertical and horizontal applications.

The mechanical seals are ideal for use on large, heavy-duty rotating shaft equipment such as mixers, agitators, and pumps. They are commonly found in the demanding pulp and paper, power generation, food and beverage, wastewater treatment and mining industries and are quickly and easily repairable, either on-site or at any John Crane Service Center.
