Frequently Asked QuestionsWhere can I purchase a KOOLAIR Pump? Pumps are available and various locations and dealers in store and online. What is the difference between a KoolAir Pump and a March LC-3CP-MD? KoolAir Pumps can run dry and a March Pump cannot. The PM500 also comes with a regular base and a upgraded Marine Base.What is the advantage of having two bases included? We include the standard base and the marine base they can choose which to use (March makes you buy the other base separately) Can anyone simply replace the base (or whatever part has the dry run protection)? Can distributors – if they already carry the March pump – replace the base, as well? If you purchase a KoolAir Wet End Kit and swap out your March Pump Wet End Kit, you will have run dry protection. The bases are interchangeable with a March LC-3CP-MD. How to reassemble a PM500How to reassemble a PM500
