The last plumbing decision you’ll ever have to make for your cart!

What’s Included
∙ Seaflo pump + accumulator housed in a stainless steel waterproof enclosure
∙ 1 inlet — connects to any standard fresh water tank
∙ 4 valved quick-connect outlets

This kit does not include any tubing or additional pieces. It is just the pump kit with the outlet connections.

Specs
∙ Flow rate: 3.3 GPM
∙ Pressure: 60 PSI
∙ Power: 110V
∙ Housing: Brushed stainless steel, waterproof
∙ Outlets: 4x valved quick connect
∙ Inlet: 1x valved quick connect

Why The Backbone
One system. Four outlets. Zero guesswork.
Plug in your espresso machine, pitcher rinser, sink, and hot water tank simultaneously — all running from a single pressurized system at consistent 60 PSI. No pressure drop when the rinser fires. No flooding your cart when you swap tanks mid-service.
The valved quick connects are the detail that changes everything. Disconnect any line — the valve closes instantly. No spillage, no scrambling, no downtime. Swap your water tank mid-rush and keep pulling shots without missing a beat.
The stainless steel housing isn’t cosmetic. It’s waterproof, food-service appropriate, and built to live inside a working cart for years — not a season.
This is what a properly engineered cart water system looks like.

Who It’s For
∙ Mobile coffee cart operators who are done improvising their plumbing
∙ DIY cart builders who want a plug-and-play water solution that actually works
∙ Event and catering operators who can’t afford a mid-service failure
∙ Anyone who’s already burned through a Shurflo and learned the hard way

What Operators Are Getting Wrong
The default setup in almost every DIY coffee cart build is a bare RV diaphragm pump wired directly to a tank with no accumulator, no check valve, and no serviceability built in. It works — until it doesn’t. Pressure spikes damage your espresso machine. Dry starts kill the pump. Disconnecting a line mid-service soaks your counter.
The Backbone was designed to eliminate every one of those failure points in a single install.

Install Confidence
Every Backbone ships with a complete install and plumbing guide written for cart builders, not plumbers.
