WAVE SPRINGS ARE COMPACT BIDIRECTIONAL SEALS ORIGINALLY DESIGNED FOR SHORT WORKING LENGTH AND HYGIENIC REQUIREMENTS.
Wave springs are mechanical seals designed to replace conventional round wire compression springs in applications that require a tight load deflection specification in a space critical environment. They provide a more even face loading than a Parallel or Taper Spring, and a smaller envelope requirement to achieve a similar face loading.
Bi-directional mechanical seals offer proven seal design and wave spring technology, in a range of material combinations. This is enhanced by superior design features, all at very competitive prices.
