Heavy duty Balanced Split Elastomer Bellows Seal for Agitators, Mixers and Pumps
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.
• The compression ring acts as the spring, eliminating clogging problems seen in fibrous or abrasive services.
• The wide sealing surface of the sealing ring prevents leaks even on the most worn, pitted shafts.
• Rotating assembly self aligns itself square with the shaft for true running.
• Fewer parts and simple design allow for easy installation. Seal can be readily mounted on worn shafts and out of square stuffing boxes - no modification of equipment is needed.
