Trailer JettersE-180 · ES-12 · ET-180 · Hot Water
Tow-behind Harben jetters for cities, plumbers and drain contractors. 3,000 to 4,000 PSI, 300 to 750 gallons of water and a run-dry pump that won’t quit when the tank does. This is our own demo trailer at the shop in Kensington, MN.
Four trailers, one pump you can trust
Same Harben build quality and run-dry pump on every one. Choose by pipe size, water on board and how big a trailer you want to pull.
E-180
The most popular Harben trailer. 4,000 PSI at 18 GPM with a 375 gallon tank on a single axle trailer, and a 180° hydraulic pivoting reel so you can work off the back or the side.
ES-12
Built for smaller lines and smaller trucks. 3,000 PSI at 12 GPM, a 300 gallon tank and about 5,900 lb fully loaded, with a Kubota diesel and an antifreeze system.
ET-180
Everything in the E-180 with a 750 gallon tank on a twin axle trailer. More water means longer runs between fills on big mains and storm lines.
ET-180 Hot Water
The ET-180 with hot water. Heat cuts through grease, hardened buildup and mineral deposits, and helps on frozen lines. The Harben pump can be set up for water up to 140°F.

What you get on every Harben trailer
Hydraulic reel
Reel speed control lets your operator pull the hose back at the right pace, so the debris comes out with it.
Jump Jet option
Pulses the water to help the nozzle climb past sags and bends while using less water.
Wireless remote
Optional 7-channel remote so one person can run the jetter from the manhole.
A pump that can run dry
Every Harben jetter is built around the Harben P-Type diaphragm pump. Run out of water and it keeps spinning without damage, so one mistake on a cold morning doesn’t take your jetter out of service.

Common questions
Which Harben trailer jetter is right for us?
For drains and lines up to 12″, the ES-12 is light and easy to tow. For everyday sewer work up to 18″, most cities pick the E-180. If you need more water for long runs, go ET-180, and if grease or ice is your problem, the ET-180 Hot Water. Our jetter sizer can help.
What does “run dry” mean?
The Harben P-Type diaphragm pump can keep running with no water in it without being damaged. If a tank runs empty or a supply line freezes, you don’t lose the pump. It comes with a standard 5 year pump warranty.
Can we see one run before we buy?
Yes. We keep Harben trailer jetters for demos and will bring one to your shop or job site so your crew can run it. Demos run out of Kensington, MN and Salt Lake City, UT.
Can a city buy a Harben on contract?
Yes. Harben is on the Minnesota State Contract, so Minnesota cities, counties and schools can buy without going out for bids. Ask us about cooperative purchasing in the other states we cover.
Do you service Harben jetters?
Yes. We stock pump parts, nozzles and hose, and we set up and train your crew when the jetter is delivered.
