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. Review: It works great for what I need it for. - Very good pump for the money. I looked around locally but couldn’t get anything for the same price or even close enough. I am very happy with it and just want to see how long it’s going to last before I have to replace or repair it ## Features - 100% continuous duty rating with no cool down period required - Automatically turns off when no flow is required to conserve battery power - Unique pressure switch design slowly cycles the pump for reduced switch and motor wear - Patented DXS-3 valves are made with chemical-resistant Viton for faster priming, better performance and longer life - Santoprene diaphragm for reliability, longer life and better priming ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B008YE3WA4 | | Best Sellers Rank | #494,573 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #1,773 in Lawn & Garden Sprayers | | Brand Name | NorthStar | | Color | Black | | Customer Reviews | 4.3 4.3 out of 5 stars (104) | | Flow Rate | 5.5 Gallons Per Minute | | Item Weight | 6 Pounds | | Manufacturer | Northstar Proven Performance | | Material Type | Polypropylene (PP) | | Model Number | 2685561 | | Power Source | Battery Powered | | Product Style | Diaphragm | | Voltage | 12 Volts | ## Product Details - **Brand:** NorthStar - **Color:** Black - **Item Weight:** 6 Pounds - **Manufacturer:** Northstar Proven Performance - **Material:** Polypropylene (PP) - **Maximum Flow Rate:** 5.5 Gallons Per Minute - **Power Source:** Battery Powered - **Style:** Diaphragm - **Voltage:** 12 Volts ## Images ![NorthStar NSQ Series 12V On-Demand Sprayer Diaphragm Pump with Quick-Connect Ports - 5.5 GPM - Image 1](https://m.media-amazon.com/images/I/71Z76MtjDKL.jpg) ![NorthStar NSQ Series 12V On-Demand Sprayer Diaphragm Pump with Quick-Connect Ports - 5.5 GPM - Image 2](https://m.media-amazon.com/images/I/71V-LyyQjtL.jpg) ![NorthStar NSQ Series 12V On-Demand Sprayer Diaphragm Pump with Quick-Connect Ports - 5.5 GPM - Image 3](https://m.media-amazon.com/images/I/71k1Cf9BJsL.jpg) ![NorthStar NSQ Series 12V On-Demand Sprayer Diaphragm Pump with Quick-Connect Ports - 5.5 GPM - Image 4](https://m.media-amazon.com/images/I/71B2q30cJ0L.jpg) ![NorthStar NSQ Series 12V On-Demand Sprayer Diaphragm Pump with Quick-Connect Ports - 5.5 GPM - Image 5](https://m.media-amazon.com/images/I/71R2DAZgrpL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great Pump I have tried many other 12 volt pumps but this one is by far the best! *by D***O on March 13, 2014* 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.

I looked around locally but couldn’t get anything for the same price or even close enough. I am very happy with it and just want to see how long it’s going to last before I have to replace or repair it ### ⭐⭐⭐⭐ Correct replacement for my pull behind sprayer *by C***R on February 26, 2026* Saw this on Amazon for way less than the local Northern tool store had. My pumps had issues from day one and when I use this pump, I’ll solve that problem hopefully. The price at the big local store was absolutely insane. This price was way more tolerable. ## Frequently Bought Together - NorthStar NSQ Series 12V On-Demand Sprayer Diaphragm Pump with Quick-Connect Ports - 5.5 GPM - NorthStar Remote Sprayer Switch Kit - Works with Systems Up to 20 Amps, 12 Volt - NorthStar Remote Sprayer Switch Kit - Works with Systems Up to 15 Amps, 12 Volt --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/18096722-northstar-nsq-series-12v-on-demand-sprayer-diaphragm-pump-quick](https://www.desertcart.tn/products/18096722-northstar-nsq-series-12v-on-demand-sprayer-diaphragm-pump-quick) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-08*
