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
