Standards or good papers on Pump set modes?

[The WG18 Guy]

Are there standards or good papers that define different controls, such as operating modes of pump sets, for example:
[ul]
[li]Duty-Standby[/li]
[li]Duty-Assist (-Assist)[/li]
[li]Duty-Assist-Standby[/li]
[/ul]

Post the question in the pump engineering forum. You will get more responses.

I assume that the question doesn't refer to pumps for fluid power applications? If it does, then there are no electrical controls as such, just energy efficiency requirements to reduce the stand by pressure. The pumps are always running, they are just unloaded. The applications for the functions that you have listed will be extremely varied for fluid power applications and as you are an electrical engineer, I expect your question is related to transfer pumps or cooling pumps.

Look up variable displacement piston pumps, Parker e.g.

Great, I’ll repost it on the pump engineering forum. It's somewhat embarrassing to show my ignorance of the mechanical domain; my only excuse is that I’m deep into the electrical domain, and sometimes we need to control mechanical systems. Anyhow, thank you for the feedback.

I’m also new to this forum; finding the right places will take some time.

This sub forum should seriously be renamed to "Fluid power - Hydraulics and Pneumatics".
People post here by mistake all the time.

Why? Fluid Power is an all-encompassing title for power transmission via fluids as compared to transporting fluids. Pumps are important components in both.

Because of threads like this one. People see the term Fluid Power for the first time and assume it means all kinds of different things that is not Hydraulics and Pneumatics.

I have done lots of training and the first slide always says - "This is not hydraulics, it's fluid power"

Hydraulics is the study of rivers and streams and perhaps the management of water flow.

Fluid power is the transfer of power via a fluid.

Yes, I'm very much aware of the double meaning of the word Hydraulic and I'm also very much aware of the use of the term Fluid Power, especially in academia. I've been "googling" white papers for almost 20 years.
That is why I did not omit the "Fluid Power" term from my suggestion I just added "Hydraulic & Pneumatics".
The words hydraulics and pneumatics are still very much in use in the field of fluid power. Infact, some people may not know what Fluid power means (point in case; the number of wrong threads started on this subforum).

The expressions hydraulic pump, hydraulic motor or hydraulic hose are well established. Few people refer to a hydraulic hose as a "fluid power hose" or a hydraulic pump as a "fluid power pump".

Again, if you read my suggestion it says "Fluid power - Hydraulics & Pneumatics"
The Fluid Power term is not omitted. Also Hydraulics is not added on it's own but is added in conjunction with Pneumatics to avoid confusion with irrigation channels.

Again, it is not uncommon to find threads in this subforum where people who are not aware of the specific meaning of the term "Fluid Power" just post any fluid related question here. Like this thread...
