Been great and has done its job!
The pump has been working great for pumping fluid in and out of tractor tires. It’s compact and lightweight, making it easy to move around where we need it to. It’s held up great so far even with not being in the most ideal conditions at times and not always been cleaned out after every use. The only complaint I can say I have is that it’s not as quick at doing the job as I was hoping. I don’t think it quite moves the 13 gallons a minute as it is says it does, but it still does the job. I went ahead and purchased the largest on they sell, which is closer in size to the original fluid pump we had in hopes it will work as fast as it did. I thought this one was big enough since the entry hole for the fluid in a tractor tire is only a 3/8 hole, but I don’t think it can move the volume to do the job faster. Hoping the larger one will

I wanted a pump with enough power to move a small boat. tested with 5 gallon air tank. Have yet to see what it will do when fully powered. Maybe with an air tank pontoon. Boat is to small for generator and compressor. In theroy steam could be compact and powerful enough for one or two pumps. Do you know of any fuel burning small safe boilers ?

I used this on a 3 point hitch backhoe. It is actually way overkill for the unit. At idle it still puts out way too much volume. Backhoe moves like a king fu fighter. I should have bought smallest available.
Mike domonick Mike domonick
For the price it seems to be great
Tested — I have a ARO $1200 —& this happy buy-is putting out the same performance at this time — not sure how long it’s going to last though very happy with the purchase & just ordered 2 more & please note: I am using a half inch hose & reducing to a small tip for maximum height in spray chemicals inside of a ship & reaching about 42 feet…
Reinaldo Reinaldo
Great product....even better customer service !!!!
Well at first we THOUGHT the unit failed . It did not,there was an air flow issue and we did not notice it. They sent out a replacement ASAP. We discovered the problem was our own doing, so I promptly returned the new one instead of swapping . This pump is fast, and furious. It does more than the old twice it’s size unit we had and is amazing.We use it for hydraulic fluid exchanges in the field. Old out , new in. It’s great!!

NICE PUMP
This pump was purchased to replace a diaphragm pump that had been in service for several years. It is used to pump waste water through a filter prior to going into the municipal sewer system. So far, it's been working great. It runs about 10 hours a day. The build quality and construction seem to be nice, it's heavy for it's size since it's made of metal. I hope this will last a while, like the previous one.
