## Description

Seaflo 55-Series Diaphragm Pump - 12V DC, 5.5 GPM, 60 PSI with HEAVY DUTY PRESSURE SWITCH : desertcart.co.uk: Business, Industry & Science

Review: Quiet, powerful, standard fittings. Wish i'd bought this first. - Quiet, well built, feels like a little fire extinguisher. Nice big rubber grommets on the mounting bracket. Comes with a filter and some adapters but after fitting the filter on the in side, the threading let me stick standard hose adapters (the nipple with the little thread reduction inset you get everywhere for pennies) on both ends making this super easy to install. Wish i'd bought this first: Now, i had one of those small cheap pumps with the single chamber and that plastic V front/top that claims silly PSI. It had small diameter fittings and was kind of a pain to adapt to a garden hose. It just about ran the hose enough to water the garden from my water butts. I bought one of those irrigation kits. Little pump could run 1 or 2 of the little sprinklers then basically gave up. The sealfow 55-series, however, smashed it. Better pressure than my mains. I was so happy to see all the little sprinklers belting out water like they were supposed to. This thing works great and has saved the project. The only issue is i used cheap tubing with the small pump and this pump sucks hard enough to pinch the cheap clear plastic hose and kill the flow. Gonna rework the project with sturdier standard garden hoses throughout. Also, in all this abuse, pinched flow, air in the system and my water butts coughing up a small tree worth of crap under the new hi-flow... the little filter with the pump caught it all and the pump handled it all nicely. Also, even when choking due to the cheap hose pinch it wasn't louder than the little pump its replacing. It's 12v and can draw up to 17amp so decent thickness wire, a sensible fuse recommended. Given it out performs my mains supply i expect this would do a great job of running water for a caravan or boat which is what I believe its intended for. It's a serious bit of kit and unlike the clones the specs advertised are accurate. Wish i'd spent the money straight off to get the proper kit.
Review: Good quality - Gives an excellent flow rate with good pressure. It's used to irrigate the garden using water from my well. Excellent build quality and comes with filter and hose connecters.

### ⭐⭐⭐⭐⭐ Good quality

### ⭐⭐⭐⭐⭐ Powerful, quiet and robust.
*by K***R on 6 June 2025*

Works well from the box and seems robust and quiet. It is being used in an agricultural sprayer and it has more pressure and greater throughput than the old one so have had to dial back some settings. It comes with an inline filter so you don't need to purchase an extra.
