I have yet to come up with a way of ofsetting the two by 45 degrees to get
things from 60 degrees to 30 degrees.
The first draft will probably have pairs of pumps at exactly the same phase
seperated by 60 degrees of rotation.

While a rotary design will probably be a bit more powerful, laying them all
flat could be more versatile. You could place cylinders anywhere you’ve got
a little open space, rather than having to make space for a bulky cluster of
them.
Here’s a concept design I came up with (click for a larger version). I only
have one mini-pump, but this frame is designed to run one on each side.
Using this setup, each pair of pumps can be hooked up 180 degrees out of
phase, or in any 60 degree increment. Rotate one of the sheaves 90 degrees
and you can get all of the other 30 degree increments as well. Slip the
gears one tooth and you can get it down to 15 degree increments. Paired
sections can be daisy-chained, or linked together over distance using drive
shafts.

Hi David,
Thanks for the ideas. I’ll consider the planar design concept (done them
before with large pumps), but first I want to try radial. I’m curious which
design would have less moving parts? Less moving parts, less friction, higher
efficiency.
I’d prefer a design where the pump is sandwiched between two support halves,
so that it is harder for the pumps to distort the support structure. In your
design, only one endpoint of the supporting pin is fixed to the structure. This
means the pump could force the pin to twist in place, and have its shape
distorted. Using a long frictionless pin and two 24T gears would reduce the
ability of the pump to distort the pin.
