The Tsunami Pump System is designed to fill and empty sacs at an alarming rate. The tubing we use is larger in diameter so it doesn’t choke the pump, resulting in greater output.

One pump would be enough, but if you want to be running around your boat like a maniac trying to keep up with the pumps get 2. 3 pumps would be a bit overboard.
