Best-in-Class, Industrial-Grade Pump

No Cool Downs Required

Finally, a sprayer pump built to work as hard as you do without losing its cool. The industrial-grade NSQ Series on-demand pump is an engineering marvel, boasting an impressive 100% duty cycle. That means while the competition is waiting for their overworked, under-designed sprayer to cool down, the NSQ Series pump isn’t even working up a sweat.

Lasts 5 Times Longer

Building the best sprayer starts with using the best pump. With patent-pending DXS-3™ valves featuring chemical-resistant Viton, exclusive NSQ Series pumps provide faster priming, better performance and best of all, last up to 5 times longer than other brands.

Packed with Features

This NorthStar NSQ Sprayer Pump is packed with components that are designed to reduce wear and keep working, like a Honeywell MICRO SWITCH™, a Santoprene™ diaphragm and a chemical-resistant fibreglass-reinforced polypropylene pump manifold. The innovative smooth valve design provides faster primes. It also has our unique pressure switch, designed to slowly cycle the pump to reduce switch and motor wear. To conserve battery power, we gave it an automatic power switch that turns off when no flow is needed. When other pumps are in for repairs, the NSQ series is still on the job.
