1  Koolance pumps can be speed-adjusted through various control methods. Pumps with built-in speed knobs should be set to maximum when using a separate controller.

2  The pump's native hose connection is displayed. Most pumps which come with barbs can use Koolance pump nozzle bases to enable other fitting sizes.
