About Mechanical seal type 5615q

The 5615q Series is the first truly universal cartridge seal — and the modular family concept of John Crane’s Universal Cartridge will change your approach to sealing. Since the 5615q Series’ components are interchangeable, you can apply one seal family throughout your plant. This gives you the flexibility to cover more applications with less inventory, which means your maintenance is simplified, downtime is reduced, plant operating efficiency is increased and costs are lowered. The Type 5615Q is for general seal applications on ANSI and DIN process pumps serving chemical processing, pulp and paper, oil and refining, food and beverage, wastewater and other industries. The quench seal design is ideal for sealing fluids that can crystallize on the seal faces.
