FLUID END UPGRADES
MODEL 4215N
The Jetstream UNx Fluid End Upgrade is ideal for
replacing a damaged, costly, or unreliable fluid end.
It is also a cost-effective solution to increase the avail-
able operating pressure or range of pressures for those
who have already converted to the UNx. The upgrade
delivers all of the benefits of the UNx Fluid End design.
Three plunger (triplex) design
Superior performance
Greater flexibility in the field
Reduced downtime and maintenance
See UNx Features and Benefits on page B-1
Clamp-style plungers
Includes hose adapters and one rupture
disc holder
Choose an additional rupture disc holder
or a Severe Service Relief Valve as a
second safety device
Pressure gauge and burst discs not included
Bolt-on installation requires only minutes
Once upgraded to the UNx design, the unit can be
supplemented with additional fluid ends to expand
its range of operating pressures.

** Displacement (flow) values represented refer to “theoretical” flow, neglecting inefficiency resulting from compressibility of water and expansion of pressure-
bearing components. Performance data is based on power end specifications published by the original equipment manufacturer; however, some power ends
may differ from those used to determine the values above. Contact a Jetstream Solutions Provider for help with fluid end selection.
