n Table 5 Approximate impeller speeds for certain motor/gearbox combinations at different frequencies
a
Applies to standard IEC drive unit, for other types (IEC ATEX, NEMA XP, NEMA Stainless Steel, etc) this may vary.
Bearing material
a
Tungsten Carbide Silicion Carbide Dri-amond™
Chemical compatibility pH range 2-14
b
Best - inert Same as silicon carbide
Ease of installation and
handling Best Harder than tungsten car-
bide, but more brittle Somewhat better than sili-
con carbide
Survivability under dry-
running conditions Good Poor Best - lowest coefficient of
friction
n Table 6 Comparison of bearing materials.
a
The use of dissimilar materials in male and female bearings is not recommended
b
Exact value depends on particular fluid properties, temperature and exposure time.
