O-ring Wave Spring Seal for Alfa Laval Lobe Rotor Pumps
Product Description
+
This component is designed with an “O” ring mounted sealing surface with sinusoidal wave spring. It is available in narrow cross section, and 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.
It is compatible with the Alfa Laval® pump model includes the following pump ranges: "GHPD", "LKPL", "SR" and "SRU" ranges. Each pump requires two identical seals, one for each shaft.
