Type 1677 / 1677M

Sinusoidal wave spring and ‘O’-Ring mounted Mechanical Seal.

Type 1677: Stainless steel head retainer and inserted face
Type 1677M: Monolithic head (optimal heat dissipation)

Both are stocked as a standard assembly with anti-rotational Type 8 DIN LONG ‘O’-Ring stationary face.

The one-piece double wave spring provides superior strength and reliability compared to welded multiple-part wave springs which are prone to breakage under pressure.

Commonly used in chemical process industries.
