Thinking about the difference in pump speeds required for different objectives (transferring vs. filtration) one thing that could be done is to get two multi-sheave pulleys and put them in opposite orientation on the pump shaft and motor shaft. That way you could change ratios like on a drill press or 12 speed bike, especially if you put your motor on a pivot plate like Billy's and mine are where the motor weight keeps tension on the belt.
