|Quick Reference Liquid Guide
|High-Viscosity Liquids. Internal gear
pumps are often a good choice.
|Sanitary Liquids. Sanitary lobe pumps work well
for most food, beverage, pharmaceutical, and biotechnology applications.
|Solids. Pump selection depends on the particular
application. For food-type applications containing solids, begin searching sanitary
lobe pumps. For slurries and other industrial-type solids, start with internal gear
|Corrosive Liquids. Proper selection of the right
materials of construction will have the greatest impact on pump performance.
Composite external gear and stainless steel internal gear pumps are good starting points.
Check out Pump School's page on
and corrosive liquids.
|Abrasive Liquids. A number of factors can combine
to minimize the effects of abrasion. Begin with internal gear pumps manufactured
with hardened steel parts.
|Toxic, Hazardous, or Hard-To-Seal Liquids.
Preventing leaks is critical for handling these fluids. Magnetically-driven or
mechanically sealed internal or external gear pumps offer a good starting point.
|Extreme Temperature Conditions. Internal gear
pumps with jacketing features offer excellent temperature control. Learn more about
handling high-temperature liquids in Pump School's
"Tough Application" section.
