I strongly suggest you make contact with Tim Cocking or Gary Sandler at Australian Fluid Handling. I have found them to be very professional in dealings over many years. Please note also that AFH can make the multiple pumps into a skid unit with pumps, valves, meters, gauges, drip tray etc. I have seen these previously and they are a real treat.
