These are pre-assembled cartridge design mechanical seals, which required no measuring process for installation. Simply slide the seal onto the shaft, bolt down the gland, tighten the set screws, and remove the location plate. The seal faces are positioned in the gland for maximum protection. The flush position maximizes face cooling. These cartridge balanced seals are independent of direction of rotation being designed to handle slurries, sludge, thick syrup, and polymerizing fluids. The spring provided in the cartridge construction are being isolated from the fluid enhancing the seal life.

Single spring seals are compactly designed to ensure efficient handling of liquids containing solid particles like slurries, sludges, sewage, viscous and abrasive materials. Both the faces of such seals are designed to take care of the presence of solid particles in the liquid which would otherwise damage the mating faces and contaminate the process.

Salient Features

Single spring seals are engineered for non-clogging and self cleaning performance especially when handling contaminated liquids. The superior design of these seals helps to handle the considerable axial play of shafts during operation. The compactness of single spring seals ensures easy handling, installation and provides trouble free service with virtually no maintainence. 

Wave Spring seals are designed for pumps working with fluids with suspended particles, sludges,high viscosity liquids etc. Typical industry usage is dairy, brewery and pharmaceutical applications. Compact in design these seals can be utilized in smaller stuffing boxes. The standard design features positive drive via the grub screws, which are also used to set the seals working length. The uniform force that a wave spring provides gives consistent axial movement and dynamics. The design features a crest-to-crest wave spring and reduces the risk of corrosion and fracture as can be experienced with welded wave springs.
