I'm attempting to design a system that consists of 4 secondary(ABCW), 1 primary(Film) tank, and a pump. The idea being to Transfer the contents of each secondary tank to the primary one, then back to the source tank before repeating the process for each of the remaining secondary tanks.
The simplest way to do this would be with a 2 way pump, but they seem to be very expensive.
So I've been trying to design around a uni-directional pump, but the simplest layout I've come up with requires 3-4 solenoid valves to route the flow back in the reverse direction.
Not knowing the first thing about hydraulics, I'm hoping this isn't the optimal design. Could anyone point me in the right direction? Or show me an affordable ≥5L/min bi-directional DC pump?
- Edit: the volume of the tanks is ~1L
- Edit 2: Affordable = Ideally under $100, not over 200
