Virtual Training Workshop

If you missed the Virtual Pump Workshop held in June 2020 don't worry you can now access the recordings.

Pumps are an integral part of the pulp and paper making process. Reliable and efficient operation of pumping systems is critical for operability and profitability.

The workshop covered key topics including Pump Sizing and Variable Speed Drives; Cavitation and Net Positive Suction Head; Rheology and Pumping of Pulp Suspensions.

Presented by Dr Martin Atkins, School of Engineering, University of Waikato, the workshop will be held over four session and is aimed at technical, maintenance, and operational staff who design, operate, maintain and troubleshoot pump systems.

 

 

MODULE 1: PUMP SIZING AND VARIABLE SPEED DRIVES 
MODULE 1 - VIDEO
Presentation: Module 1 - Pump Sizing VSD

Pump systems are of critical importance in many industries and need to operate reliably and efficiently. However, it is estimated that as many as 75% of industrial pumps are oversized and as a result, pump systems are operated at far from optimal conditions. Pump systems are large energy users and there are many ways of reducing energy costs by utilising a Variable Speed Drive. However, depending on the situation, the economics of using variable speed drive may not be viable. This module will address the question of how to size a pump correctly and how to assess when a variable speed drive would be suitable.

MODULE 2: CAVITATION AND NET POSITIVE SUCTION HEAD

MODULE 2 - VIDEO
Presentation: Module 2

Cavitation and Net Positive Suction Head (NPSH) are important yet often misunderstood principles that can have a major impact on pump systems and their operation. Poorly designed pump systems and oversized pumps can cause problems with cavitation and not adequate NPSH. This module will cover why and when cavitation occurs, the effect it can have on pumps, available and required NPSH and how to design systems to operate well.

MODULE 3: RHEOLOGY AND PUMPING OF PULP SUSPENSIONS

MODULE 3- Video
Presentation: Module 3
Pulp suspensions are unique in their rheology (i.e. how they flow) which has important implications for pumping them. This module will cover the basics of pulp rheology and how these apply to pumping and design of pumping systems. An overview of the operating principles of medium consistency pumps will be given.

MODULE 4: TROUBLESHOOTING EXAMPLES

MODULE 4 - VIDEO
Presentation: Module 4

This module will go through some examples provided by participants around problematic or inefficient pump systems. Examples may include energy/efficiency improvement, resizing, implementation of variable speed drives. Measures to implement pre-screening assessment techniques at a mill level to quickly identify opportunities for improvements to pump systems will also be covered.
