regenerative pump, head and flow rate calculations
regenerative pump, head and flow rate calculations
(OP)
I am trying to calculate theoretical pump curves for a regenerative pump. I am doing an feasibility analysis. This type of pump is also referred to as a peripheral pump. These pumps are used in residential water systems and for automotive fuel pumps. They are used for high head, low flow conditions.
I have encountered papers by Meakhail & Park from Korea and Quail & Scanlon from Univ. of Strathclyde.
I would very much like formulae where I specify geometry, speed, fluid, and such and calculate head and flow.
Many thanks,
Douglas

I could not find any threads on Eng-Tips for peripheral pumps. Regenerative pumps were mentioned in two threads. One only suggested that a regenerative pump may be a solution, the other, which I cannot locate this morning, indicated that almost no one who relpied was familiar with this type of pump. That is why I attached a drawing.
I found 3 early thesis papers from MIT from the 1950s which are very informative but do not indicate the relationship between flow rate, head, diameter and rotational speed of the impeller.
I have googled “prediction of flow rate for a regenerative pump”, ditto for peripheral pump, ditto for design equations.
I have searched Strathclyde's archives.
I have searched for the names of of the authors of the papers that I have mentioned
There is not site for peripheral or regenerative pumps on Wikipedia.
There are no theoretical information on peripheral pumps on the websites of EBARA nor Petrollo. I have used peripheral pumps from these manufacturers and the vendors do not understand the design equations that govern the performance of the pumps.
I have found a Chinese site discussing the effects to Reynolds number which did not yield any design equations.
In answer to your question, I have pretty much exhausted the resources that I have at the moment and have hoisted the white flag and do request any help that is available.

It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)

TenPenny, I have not seen this paper. I have downloaded it and will review it today. Thanks!
ProcessHVAC & Artisi, I am interested in if a peripheral pump will be suitable for speeds significantly lower that what is commercially available. I am away from my workshop or I would experiment.
thanks

When you say significant lower speed - what speed are you talking about?
