NorthStar NSQ Series 12V On-Demand Sprayer Diaphragm Pump with Quick-Connect Ports - 5.5 GPM

Its been four very hard years, this thing has taken a lot of abuse, including spraying wetable vineyard sprays. ... the rest is my first review...At 5.5GPM this pump is a monster. If your spray requires constant mixing this is your best bet. At 5.5GPM the bypass creates a great recirculation rate, keeping the contents in the tank well mixed for consistent spray applications. Durability ... I have several NorthStar pumps, other than a clean rinse after each use I have done no other maintenance. I have a 6A vineyard which requires weekly spraying and am on my fourth season and no pump failure. I only bought this one as a backup as the sprayer has become an invaluable tool and I cannot afford to be without it. In the meantime it is sitting in my basement with my 12V Car Jump/Booster battery as sump a backup. At 5.5GPM that pushes 330GPH through a 5/8 garden hose.

I bought this pump to replace a 13 year old FIMCO pump for my 25 gallon FIMCO spot sprayer. I wish I'd replaced it years ago! The old pump was a 2.1 gpm 60 psi 12 volt pump, underpowered for spraying a thousand feet of fence line and lots of poison oak with (ick) Roundup. This 5.5 gpm 60 psi pump sprays to drip off in a fraction of the time, making short work of an odious job. The unit installed without complication in the exact same footprint on the tank.

It worked well on my sprayer.

Thede North Star pumps are excellent. Have used them for a number of years. take care of them; flush out after use, don't let them freeze and they last a long time. this one ordered as a spare since original is 5+ years old

Bought this as a replacement and have been very happy with how much better it works than the original. I recommend making power connections with 10 gauge stranded copper to prevent overheating and to extend motor life

Bought the pump mid Dec, installed mid Jan, ran 5 secs and stopped, fuse not blown, pressure switch not made. NorthernTool, will not replace it, even though it was inside the return-by date. I recommend not buying anything from Northern Tool, there are any number of other vendors that stand behind their products, and care about taking care of their customers.

Arrived, wires disconnected, downloaded manual to hook up wires, pump worked and had water in it already. The outlet attachments? One was a 3/8 inch nipple the other 1/2 inch pipe thread. Have to order correct ones and the pump is noisy. I found 3/4" quick connect to 3/8" barb for $12 on Amazon. I'd send this back but it took a week to get here and I have weeds to kill.

I bought this to replace the stock 2.1GPM pump on my tow sprayer. I wanted a higher flow pump so I could move a little faster. With this pump, I'm able to flow 2 GPM at 40 PSI, which to old pump could not do. For refernece, I'm using a 40 gallon tank with a 7ft boom and 5 AIXR red nozzles.
