Overview

Most pump problems are system problems. A pump selected for a duty it never sees runs off its curve, and the symptoms arrive as cavitation, seal failure, high vibration or a bearing life measured in months. Throttling a discharge valve to control flow, running two pumps in parallel without checking the curve, and a suction arrangement that never had the NPSH available are the usual causes, and none of them is fixed by replacing the pump. This week works from the curve outward: what the pump will do, what the system is asking of it, and what the gap does.

It runs 7 times over the published calendar, in 6 cities and live online. Every date is the same programme with the same content and the same certificate.

What you will be able to do

  • Read a pump curve and locate the actual operating point on it.
  • Calculate NPSH available and compare it against required, with margin.
  • Diagnose cavitation, recirculation and dry running from their symptoms.
  • Assess a control method against throttling, recirculation and speed change.
  • Trace a repeat seal or bearing failure to the operating point that causes it.

Who should attend

Operators and operations engineers responsible for pumped systems, maintenance and rotating equipment technicians and engineers, and reliability staff investigating repeat failures.

Is the level right for you?

This is an intermediate level programme. It assumes you are working in or moving into the area it covers, and it is built around your own material rather than a case study. If you are unsure, ask an advisor before registering rather than after.

How it is taught

Short input, then work. Across 5 days of roughly 6 teaching hours each, the balance sits deliberately with the second: a programme where the trainer talks for six hours produces notes rather than capability.

  • Your own material

    Exercises run on situations delegates bring, not on a case study written for a different organisation in a different decade.

  • A capped cohort

    Small enough that everybody is asked something. Executive programmes are capped tighter still.

  • Practice under scrutiny

    The difficult conversation, the challenged assumption, the decision defended out loud. Judgement is not built by watching.

  • Something to take back

    Each day ends with a thing you can use on Monday rather than a slide deck you will not reopen.

The programme, day by day

Day 1How a centrifugal pump behaves

How a centrifugal pump behaves

  • Head, flow and the curve, and what the impeller sets
  • Efficiency, best efficiency point, and the cost of running away from it
  • Affinity laws, and what changes with speed and diameter
  • Power, and the duty at which the motor is sized
Day 2The system decides the duty

The system decides the duty

  • Static and friction head, and building the system curve
  • Where curve meets curve, and why it moves
  • Series and parallel operation, checked rather than assumed
  • Valves, strainers and the resistance nobody counted
Day 3Suction and cavitation

Suction and cavitation

  • NPSH available, calculated from the actual arrangement
  • NPSH required, and the margin to hold
  • Cavitation and suction recirculation, told apart
  • Vapour pressure, temperature and the fluid being pumped
Day 4Mechanical consequences

Mechanical consequences

  • Seals, and the operating conditions that destroy them
  • Bearings, lubrication and load from off curve running
  • Axial and radial thrust, and where it goes
  • Vibration as a symptom of a hydraulic cause
Day 5Operating and controlling

Operating and controlling

  • Throttling, recirculation and variable speed, compared on cost
  • Minimum flow, and what happens below it
  • Starting, stopping and switching duty
  • Monitoring that would show the duty point drifting

What you leave with

  • A system curve for one of the delegate's own pumped systems, with the duty point marked.
  • An NPSH assessment with the available margin calculated.
  • A failure analysis linking one repeat failure to its operating cause.

The certificate

A GATI certificate recording what you attended, issued after the programme has run and attendance has been taken. Attending at least 80 per cent of the days earns a certificate of completion; attending less earns a certificate of attendance stating exactly what was attended.

Every certificate carries a code that anybody can check against GATI's own record, which is what makes it worth holding. It records participation. This site will not imply one it does not have.

Questions

Who is Principles and Operation of Centrifugal Pumps for?
Operators and operations engineers responsible for pumped systems, maintenance and rotating equipment technicians and engineers, and reliability staff investigating repeat failures. It runs at intermediate level within Maintenance and Reliability, so it assumes you are working in or moving into that area rather than meeting it for the first time. If you are unsure whether the level fits, ask an advisor before registering rather than after.
How long is it, and what does a day look like?
5 days, running to roughly 6 teaching hours a day. Sessions are built around your own material rather than a case study, so a day alternates between short input and working on something you brought. The full outline is on this page, day by day.
What does it cost, and what is included?
The next published date is Live online at US$995 per delegate. The fee covers tuition, all programme materials and the certificate. Travel, accommodation and visas are arranged by the delegate. Fees vary by city, and every published date shows its own.
Can it be delivered for my organisation only?
Yes. Any published programme can run as a private cohort, on dates that suit you, in your city or online, built around your own material. That is a different conversation from registering an individual, and it starts with what capability you are trying to build rather than with a course title.
What certificate do I get?
A GATI certificate recording what you attended, issued after the programme has run and attendance has been taken. Attending at least 80 per cent of the days earns a certificate of completion; attending less earns a certificate of attendance stating exactly what was attended. Every certificate carries a code that anybody can check against GATI's own record.
Is the online version the same programme?
Yes. The same faculty, the same material, the same cohort cap and the same certificate. It is not a recording and it is not a reduced version. It exists because travel budgets and visa timelines rule people out of a room they should be in. The classroom version runs in Nairobi, Kampala, Gaborone, Dubai.
