Pope is a great company that makes a great machine. You could call them the Tamisium of the Wiped Film right now. (If they don’t pick make some advancements in their design, they’ll fall behind in due time).
You can crank it out even on the smallest model, it’s all about operator efficiency. Pump choice is crucial too. That said, if you’ve got the budget for a 6" Pope, you should look at the Chemtech/Helderpad unit. They provide a diffusion pump and rotary vane - and have a nicer; more plant-style footprint than the Pope.
