Customer Reviews for VEVOR Water Diaphragm Pump, 20.8 LPM Flow, 4.8 bar Rated Pressure (2.8-6.9 bar Adjustable), 12.7 mm MNPT Self Priming Sprayer Pump with Pressure Switch for RV Camper Marine Boat Lawn, FCC Certified

It works great but only lasted 3 days they are sending me a replacement one hopefully it works better

I used this pump to run water 80’ thru a garden hose from my rain water catchment tank to water newly planted grass. It is very reliable and powerful! It had a four foot head on the pump and gave me 48 psi at the end of the hose. I did have an issue with it not shutting off a few times after the nozzle was closed and there was no flow, but that could be due to the long run of the hose. I highly recommend this pump, it won’t let you down.

I am using this on my RO system. It costs less then a repair job on most pumps in this kind of service. A couple of advantages is that the high pressure ability of this pump puts the 70 psi RO pressure in the normal range. Also the fact that it has a separate low pressure adjustment and high pressure adjustment means that I can remove the excessive idle time required on the other pumps with just the singe setting. This continuous high pressure means more gallons per day. This pump is also super quiet and smooth running. I can't report on the life expectancy of this pump yet, but otherwise satisfied.

Volume is outstanding. Knowing that weed killer, fertile and other chemicals won't create issues with is great.

Works as described.

I loved I installed on my boat works pretty good

Have it plumbed to my shallow well because my 3/4 Hp well pump burned up. I have all the water pressure I need. Just had to adjust the pressure screw about a 1/2 turn so it would cut off automatically, but it works great.

All seems very good so far

Works good, not as powerful as I needed, but I will work for now.

This pump Is way quieter than my last pump and did a better job when accompanied with the accumulator tank. A lot more pressure too than my old pump that was brand new and broke. Also be careful when tightening fittings on the male threads it can break off the pump leaving it useless....my last pump suffered that fate.
