“Pumping and Hydraulics’ Solutions for Irrigation and Water Supply”
Irrigation systems such as this golf course, can consume up to $300,000 (NPV) in pumping electricity costs over 15 years. Introducing Energy Efficiency initiatives for these systems can yield significant energy savings. Photo: R Welke
Module 2: PUMPING
Of all of the Limits of Operation, Net Positive Suction Head is the least understood concept in pumping. This course clearly demonstrates NPSHR (required) and NPSHA (Available)
Many attendees expressed the "WOW" factor from this presentation, with the light suddenly being switched on after decades of mis- understanding the whole NPSH concept!
Attendees are given an Excel program developed by Tallemenco to calculate the suction limits of operation of a pump given its NPSHR, altitude, water temperature and suction pipework configuration.

Module 3: FILTRATION
Did you know that a pump and a cricket bat have something very much in common? Watch the video in this training course and find out what it is!
The Module takes about 1.5 hr to present.

Module 4: FLOW METERING
It can't be managed if it can't be measured (accurately)!. Water metering presents the greatest opportunity for improved energy efficiency through improved water management.
This module takes about 1.5 hrs hours to present.
Some flowmeters require no straight pipework, such as this hydrometer., left. Photo: Rob Welke
Module 5: PIPELINES
Substituting pipe to save costs can have a devastating effect on residual pressure, irrigation efficiency and therefore energy efficiency. Chart: Rob Welke
Module 6: FLOW MANAGEMENT
This module takes about 1.5 hrs to present.
Advanced Flow Management Controllers can be enormously helpful for irrigation efficiency.
