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

Ordered for Boss, quick replacement for old non-working pump, I've run over,100 gallon of weed spray through it in 2 days, never missed a beat, this was an upgrade for smaller pump, which cost more, so far its proven itself.

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

It worked well on my sprayer.

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.

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.

This pump was purchased to water newly planted trees and to spray weed killer on the yard. The pressure is great! It pumps at or better than the pressure from my house garden hose. Two Boomless Spray nozzles rated at 2 gpm were connected and it is perfect. I've only run this for about a month, but I'm very happy with the operation and value of this pump.

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.
