Referring again to Figure 1, a key to controlling surges in pumping systems is to control the rate of increase and decrease of the flow velocity into the system. Pumps should be sized for the expected flow requirements. Oversized pumps can create havoc in certain pumping systems.

Typical pumping systems contain five basic components: pumps, prime movers, piping, valves, and end-use equipment (e.g., heat exchangers, tanks, and hydraulic equipment). A typical pumping system and its components are illustrated in Figure 1 on page 4. Pumps Although pumps are available in a wide range of

In these pumps, the outside diameter of the impeller is less than an ordinary centrifugal pump, increasing flow volume. Ventilation Ventilation and heating are required if the lift station includes an area routinely entered by personnel.

VARIABLE SPEED PUMPING - Energy

www1.eere.energy.gov

Proper selection of pumps, motors, and controls to meet the process requirements is essential to ensure that a pumping system operates effectively, reliably, and effi-ciently. All pumps are divided into the two major categories of positive displace-ment (PD) and rotodynamic. PD pumps can be classified into two main groups: rotary and reciprocating.
