Diaphragm pump design

[Parsnip]

Please could someone advise on either how to design variable volume diaphragm pumps for use in a water flow balance system - or point me in the direction of a good web resource.
Any help would be much appreciated.

What's a water flow balance system?

Hiya,
A fluid balance pump system is one in which volumes being provided by a diaphragm pump are controlled by the fluid being returned to another diaphragm pump. Does this help?

Why try and re-invent the wheel by attempting to design a diaphragm pump when there are any number available on the market from reputable manufacturers.

Because this is for a very specialist application and we can not use proprietry items.
