Q: Can I reduce the flow to 150 gpm?
by Tim Stock from Wisconsin on July 01, 2016

A: Tim,

You can reduce the flow if you install a ball valve on the discharge side and use this for your flow control. As long as you are not reducing your flow more than 90%-100%, you will not cause and harm or damage.

Please let us know if we can help with anything else.

Monster Water Pump For The Price
Pumped water from a creek five feet below the pump into a 2000 foot 4 inch pipe with a 37 foot rise. This pump actually did it, all though flow was low. Would pay for a large fuel tank model. Had to fuel it every 1.5 hours.
Pros: Price, Easy To Use
Cons: Small fuel tank, Choke is labeled backwards

4" Pump In Pa Gas Well Industry
I work for a company in the PA gas well industry. We started with one of these 4" pumps, but now have about 4 of these pumps. They have run 24 hrs a day for a week or two straight at a time and they have worked flawlessly. They start on the first pull every time.

The pump is self priming after the first manual prime you do. You should manual prime any pump the first time anyway or you could/will burn up the shaft seal(water keeps seal cool). We have used them in the bitter cold winter... more

Good Pump Have Bought Two Of Them
This pump powers my 5 in dredge and pumps water for above water mining. I would like to say that i was a big fan of the price and the way it had worked. Not such a big fan about the condition it arrived to me in. It was a prompt delivery tho about 3 days to my door for free. But the metal rack that it uses as its motor mounting frame came bent and bowed...... The pump worked fine but because the frame was tweeked the oil seal went out of it in less than six months.... I think that was the... more

24/7 This Pump Can Get It Done!
Our company handles moving water into holding tanks for oilfield frack jobs. We normally use diesel powered self priming pumps that do 1500-2000 gpm. Last summer our big pumps went down and to fill in the down time I bought 2 of these pumps.

I questioned the price and quality, but decided to give them a try out. Glad that I trusted my gut feeling on this one because these pumps performed beyond anything I could have imagined. We are buying 6 more this year because we are convinced these... more

3 Inch In 2015... 4 Inch In 2016
The 3" pump worked fine in 2015. I am donating the 4" pump to the farmer who provided my test grow acreage in 2015 so that he may improve his field sprinkler cycle time. I assume 2016 will have successful results but I will not provide an update.

The sheet metal channel mounting beams will not resist heavy drop handling during shipping. They are fairly easily straightened with removal of the engine/pump unit however.
Pros: Quiet, Price, Light Weight, Reliable

Not Powerful Enough
I purchased the wrong pump. It worked fine and met all its specifications regarding flow rates etc., but unfortunately the ingress of water to my pond from a lagoon was a little to fast to overcome. We were able to lower my small pond by about 1 foot every 2 hours but were never able to get that last 18 inches out. I may have to purchase enough similar pump in the future to accomplish the drainage I require.
