(2026/2027) 100% SUCCESS
Vane pump Advantage - Correct Answer -Handles thin liquid and realtive high pressures, compression for
wear through vane extension.
Vane pump Applications - Correct Answer -Aviation services-fuel tranfer, alchcol, refrigeration
Lobe pump Advantage - Correct Answer -pass medium solids
no metal contact
Lobe pump Applications - Correct Answer -High viscosity material
Food appilcations (peanut butter, molasses)
Coupling - Correct Answer -connecting coaxial shafts so that one drives the other.
2 MAIN goups of coupling - Correct Answer -Rigid and Flexible
, Soild couping - Correct Answer -connects shaft end together rigidly
use only when true alignment
must be aligned
