So, if the print tank is approximately 3" in diameter or 75 mm, the area is 4418 mm2, and 1/3 rotation of the pump results in a Z-axis increment of 0.0456 mm. That's not great resolution, but it means the maximum resin level adjustment rate is only 13.5 mm/min or 0.228 mm/sec.

0.045mm is a good enough resolution for most prints (0.05 is considered typical layer thickness for laser based printing), and can be doubled (ie rise halved) to 0.0225mm by increasing the tank diameter to 8,5 cm, and almost tripled (approx 0.015mm) by going to 10cm.
Of course that also decreased the max rise speed, but then again, how many filament 3D printers complete a 0.2mm (standard thickness for those printers) layer in 1 sec?
Also faster pumps usually also mean less accuracy...
