GW68E Wave Spring Seal for Johnson and Hilge lobe rotor pump

This component is designed with an “O” ring mounted sealing surface with sinusoidal wave spring. The drive of the shaft is fastened using set screws. The wave spring design provides even closing forces around the sealing face circumference, which lead to improved pV capability, outstanding axial movement capabilities and higher sealing performance. Its monolithic steelhead design enables higher performance in abrasion resistance and high temperature applications.
It has short installation length and reduced radial clearance, which is highly suited to rotary lobe pumps and other slow shaft speed operations.
Its unique and distinctive stationary profile is designed to locate into the stationary recess of the range of rotary lobe pumps. Please note that 30mm size stationary has a single semicircular anti-rotation slot, other sizes have three flat anti-rotation slots.
It is compatible with the Johnson® pump model includes the following pump ranges: "LKPL", "NMOG", "SR" and "SRU" range models when fitted with "R90" single seals. And it suits Hilge® pump model: Domina I-710, I-720, I-730, I-740, I-750.
