Locke Well & Pump Company

I currently have a stenner pump, model 85MPH17, to pump bleach into system to treat the drinking water. We are on well water. Would it matter if I replace it with model 85MPH40? What are the disadvantage and advantages?
Most of the time there are only 4-6 people in the house. But 1-2weeks out of the year, I may have up to 60 people in the house. Also, would I be able to buy it online and have someone pick it up for me? Thanks.

Not a good idea. You would have to turn the 40 gpd pump down to low and that would cause excessive wear in the feed rate control.
