Affinity laws and power estimation are presented. Net positive suction head (NPSH) is explained, and the performance of multiple centrifugal pumps piped in parallel or series is quantified.Stephen M. Hall PERules of Thumb for Chemical Engineers (Sixth Edition)...
Why is there air in my system? What is Water hammer? What pipe size should I use? What happens when centrifugal pumps are run in parallel? What happens when centrifugal pumps are run in series? What happens if you do not have enough submergence?
Unequal pump capacity and the plotting mfgr's pump graphs. In excel, plot the mfgr's curve and put use a grid which corresponds to a fixed number you choose for the "head" units, then input the corresponding flow units so you can plot the graph. If you have pumps in series make the...
The IRON propeller pump series QT/QTe is primarily operating in anti-heeling applications. The pump job is signified by bi-directional operation, low head and flow variating from smaller to larger capacities.The QT anti-heeling pump series from IRON are based on the propeller principle, ...
Interchangeable installation dimensions with other Universal Series pumps Theory of Operation Time-tested Waukesha Cherry-Burrell® rotary pump; circumferential-piston operating principle In the Waukesha Cherry-Burrell design, arc-shaped "pistons” (rotor wings) travel in annular-shaped cylinders machined ...
Pressure pulsations around the “S” curve conditions of the pump-turbine were simulated. The results proved that the PANS method could predict the relative peak–peak amplitude successfully, and it agreed with the experimental data. Moreover, low frequencies in pressure spectrum could be captured ...

The LSGX-Series curve provides superior flow over a wide range of typical pressures - necessary for multi-unit developments and "large-area" low pressure sewer systems. The 2-stage Liberty Pumps LSGX203M allows installation of a centrifugal design where progressive cavity style pumps have tradition...
