Harben High Pressure Pumps
High Pressure PumpsP-Type & Century
The diaphragm pumps that power every Harben jetter, also sold on their own for replacement and industrial cleaning. Both can run dry without damage.
P-Type or Century
Pick the P-Type for jetters and everyday cleaning, or the Century for higher pressure and flow.
P-Type
Change pressure and flow without changing pistons, up to 6,000 PSI and 18 GPM. Multiple cylinders mean no pulsation, and it can pump sea water or hot water up to 140°F.
Century
Up to 10,000 PSI and 40 GPM with low running costs. Pumps low lubricity fluids with ease, runs with minimal pulsation and is simple to pressure compensate.

Why diaphragm pumps last
A Harben pump keeps the water away from its moving parts with diaphragms, so it can run dry, handle dirty water and keep going season after season with long service intervals.

Common questions
Can I buy a Harben pump on its own?
Yes. We sell the P-Type and Century pumps for replacement, for building your own equipment and for industrial cleaning. Tell us your pressure, flow and drive and we’ll quote it.
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.
How often does it need service?
Harben pumps are known for long service intervals. The manuals list the schedule, and we stock parts and kits.
Can it pump hot water?
The P-Type can be configured for hot water up to 140°F, which is how the ET-180 Hot Water jetter works.
