to allow for draining of residual fluid after the cleaning process. Horizontal porting prevents fluid from completely draining from pump. Finally, Saline can cause leaking issues with internal seals. In an effort to prolong seal life expectancy, a more robust seal is needed to ensure a clean, leak free pumping. The ITT Solution. The Ultima Rotary Lobe pump designed with 316L stainless steel rotor casing and rotors with a surface roughness finish to 0.5 Ra will allow the customer pump saline...

surface finish. Roughness average, Ra Readings of 4 micro inches have been produced. Grob Rolling Method. With Grob cold roll forming, the groove is formed down between the teeth. The material displaced from area "A" (see sketch below) forms the tooth tip area "B". This is a severe reverse flow. With no elongation, the area of raw material displaced must be the exact same as the area it was displaced from. Through this process, we're able to roll both even and uneven numbers of teeth...

Proper Film Thickness key to Bearing Survival
arithmetic-average roughness to rms, and with nominal hmin = 0.0008 in., = 9. After a few start-ups and running hours, babbitt typically polishes to about Ra = 16 in., while the journal burnishes to the same or better surface finish. An initial (and marginal) = 9, then climbs quickly to about 28 in service
