Hello everyone,
I've been doing loads of research but have not come to any meaningful conclusions so I thought asking directly might help! I am looking at upgrading our water system pump at our horse farm. Some background first, the building is 300 long and 100 foot wide with 4 aisles, each 100ft long with 1 1/2" PVC running down each. Each aisle has a slop sink and about 4 hose connections. There are also two horse showers. As you can imagine this system can get to be pretty demanding. Our well company put in a tiny Grundfos JP07S-CI 3/4HP 15GPM shallow well pump a while ago and it just isn't cutting it anymore - it trips out on low limit almost every day in the summer, not to mention all the hoses trickling during watering time. The system pressure is set at 55PSI. We have 3 storage tanks, x1 500 gallon and x2 275 gallon tanks all connected together and fed by another well pump that is underground outside. These tanks feed the system pump directly, it is on the floor next to them.
My question is is it possible to put too big of a pump in? I am looking at a new Dayton 5WXU1 3HP 138GPM (at 15ft head) centrifugal pump. I know someone who is selling it fairly cheap. My main concern is, if the water system demand is low to moderate about 70% of the time, will this cause the pump to cut on and off a lot since it is such a high flow rate? We do have an 81 gallon pressure tank on the system as well. We could push the PSI up to around 60 or 70 as we have all PVC, but even then, will the pump just cycle like crazy damaging it? I know it would obviously handle the high demand perfectly during the day when everyone is watering and showering their horses, I just don't want to put it in and then have it either burst lines because it rose the pressure too quickly or have it die in a month from cycling. I just don't know what will happen.
I would be very appreciative of any suggestions or input! Thanks in advance!
