Our pump classes discussed the fundamentals of positive displacement and centrifugal pumps. When to use which pump, types of products appropriate for each pump along with temperature, viscosity and sizing of pumps were all addressed during the session. We also had a hands on portion to dissemble and reassemble pumps and seal configurations and applications. The Valve session was very similar. Stem valves were the primary topic with time spent on divert, shut-off and mix proof. The different body configurations, actuator sizing and control top technology were all a part of the class.
