3600 UNx™
Pumps and Fluid Ends


Maximum Efficiency. Mid-range Power.

3600 UNx™ Series bareshaft pumps have the power to tackle tough cleaning jobs and reliable performance that contractors and plants can count on. Quickly change between operating pressures for any Jetstream bareshaft pump with a fluid end conversion. Conversions packages are available for pressures as low as 6,000 psi to 40,000 psi (400 to 2750 bar).

Closely related to the 4200 series of Jetstream pumps, the 3600 series differs only in the crankshaft design. 3600 Series pumps operate at an input power between 200 – 270 HP with a shorter crankshaft stroke length than the 4200 Series. Otherwise, it is identical to its bigger brother the 4200 Series bareshaft pump and even shares the same fluid ends with different flow ranges based on the horsepower.

The UNx™ Pump stands as the workhorse of the industrial cleaning world with innovative American manufacturing, ductile iron power frames, heat-treated billet alloy steel crankshafts, and the largest bearings of any comparable pump.

Available on Jetstream’s X-Series waterblasting units or as a stand-alone pump for those building their system or replacing a complicated, worn, or unreliable pump.
