VARIABLE SPEED PUMPING - Energy
www1.eere.energy.govProper 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.
Improving Pumping System Performance - Energy
www.energy.govTypical 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
Surge Control in Pumping Systems - Val Matic

Collection Systems Technology Fact Sheet: Sewers, Lift Station
www3.epa.govheads. Mixed flow pumps are most viable for pumping large quantities of wastewater at low head. 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.
