“Pumping and Hydraulics’ Solutions for Irrigation and Water Supply”
Session 3: NPSH & Pump Suctions
Single pump selection can become quite complex   Graph: R Welke
A range of Tallemenco designed software will be free issued to each student, enabling irrigation pump selection with various pipe types, diameters and friction values (C Values) plus pump speed and impeller trimming software. In addition, students will have access to Tallemenco's latest web based software, Hydraulic Optimisation (Hydropz).
Session 2: Pipelines & System Curves
Pipeline design may contain so many variables that pump duties become wide targets.
