FIMCO5151088 High Flo 12Volt Demand Diaphragm Pump (Upgrade), 4.5GPM, 60PSI, Can Use with Roundup

I bought this pump to replace one that froze over the winter, and I’m beyond impressed with how well it works! The internally fan-cooled motor is a powerhouse, delivering consistent performance even under heavy load. I’ve been using it for demanding tasks, and it hasn’t skipped a beat, proving its reliability and durability.The chemically resistant elastomers really boost the flow rate, making this pump noticeably more efficient than my old one. The built-in check valves are a great feature, maintaining steady pressure and preventing backflow, which gives me peace of mind during operation. It’s also self-priming, and the fact that it can run dry without damage is a huge plus for reliability, especially in unpredictable conditions.This pump is a direct replacement for several part numbers (5281372, 5275088, 5277982, 5275704, 5275498, 5274983, 5275017), and it fit my system perfectly with no installation hassles. The performance has been flawless, and it’s clear this pump is built to last.My only minor wish is that it came with more detailed installation instructions for first-timers, but since I was replacing an existing pump, it wasn’t an issue for me. If you need a robust, high-performing replacement pump, this one is an absolute winner. It’s been a game-changer for my setup!

Very good pump, second one, first one lasted 10+ years

Works great

Worked great at first but plastic housing is warped in the mold process and after few uses it looses suction has hard time maitaining pressure its a defect from the subcontractor that makes the plastic housings unless this guy is selling a new batch of pumps which i highly doubt because price is so cheap i would assume these still have deformed impeller housings i wouldnt buy again no warranty either

Quality Fimco product. Great output/pressure. Will run my 14’ sprayer bar with 7 heads with ease!

Works great easy installation used on my 25 gallon yard/driveway sprayer

Fast delivery and worked great
