5 Stars What a pump

Aaron Davenport from MI wrote (August 14, 2015):

Background: I am/got married in Sept 2015, and had the part in a backfield. Prep included flattening an acre and planting a lawn. I had no good way to water the new grass so I set about designing a watering system (I'm an engineer). I got 2, 1-inch impact sprinklers and 1000 ft of 3/4" hose for the discharge. On the suction side I ran 200 feet of 1" sch 40 PVC with a foot valve to a floating suction in a spring fed pothole pond. This little giant of a pump managed to self prime and has been running the sprinkler setup 3 times a week during a pretty dry July/August. The field is lush and green and this little pump has been a beast. I run it off the PTO of a MF 1552. Pressure runs around 125psi at the pump, 78psi at the furthest sprinkler. Can't say enough good things.

5 Stars Tremendous pump


Harold from LA wrote (May 11, 2014):

I've used this pump now for several years and have been very pleased with its ease of use, easy maintenance, and versatility. From fire watch, to high volume/pressure chemical application, this pump will deliver. If you ever need parts, the very friendly ASC parts group is more than capable to help you. I let my pump freeze one year and ASC had the parts in stock. Got me going in a very short time.

5 Stars Ferroni PTO Pump


Richard Swint from TX wrote (August 12, 2013):

This pump works.First purchased in June 2006, not used every year. Used for pasture sprayer, much superior to other similar PTO pumps, operates like new this year, 2013 for pressure and flow.

5 Stars Fire Pump

Steve from GA wrote (February 02, 2013):

This is a high pressure pump. I use it on a 250 Gal tank to help supress fire when I'm burning off around the Farm. Works like a champ!
