Actuators and design help

I hope this is a proper posting for this site.

I am looking to create a pumping system to mix an epoxy solution. The epoxy and hardener have less than 1000 centipoises in viscosity. This viscosity is less than heavy oil or syrup.

I envision two stainless steel cylinders to pump the epoxy resin and hardener. I am thinking of four ports on each cylinder, two ports would have check valves, to allow epoxy to fill and dispense as the piston moves in both directions.

Volume to produce is approximately 1 to 2 gallons per minute.
The seals would likely need to be EDM.

I would like to be able to adjust the mixing ratios of the two parts of the epoxy as well as the flow rate of the epoxy product.

Would linear actuators attached to some control mechanism control panel attached to some custom or off the shelf cylinder be the solution? How would I control the speed and accuracy of the two cylinders?

I am a novice looking for some direction.
