3020Q UNx Fluid End Upgrade - #6 Plungers

Part No: 52155

Increase productivity and reduce operating cost with a UNx® Fluid End Upgrade. Flow up to 11.3 gpm (43 l/min) at 20,000 psi (1400 bar). Designed to fit American Aero/ Weatherford FE145 and NLB 10125.

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 available operating pressure or range of pressure for those who have already converted to the UNx. The upgrade delivers all of the benefits of the UNx Fluid End design.

  • Five plunger (quintuplex) design
  • Superior performance
  • Greater flexibility in the field
  • Reduced downtime and maintenance
  • Clamp-style plungers
  • Includes hose adapters and one rupture disc holder
  • 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

20K Bypass Valve - Pump Mount

A bypass valve diverts a portion of pump flow to a low- pressure outlet and is used to prevent bogging of diesel engines when using flows at the low end of the pump’s capability or to adjust pressure on electric motor driven systems.  20,000 psi (1400 bar).  Pump-mounted.

20K Handle-Adjustable Regulator

Maintains constant system pressure when operating one or more shut-in devices. Knob-adjustable. Field-replaceable valve cartridge. For operation at 15,000 - 20,000 psi (1000 - 1400 bar). Pump-mounted.

UNx Spare Parts Packages

Packages include all major fluid end replacement packaged together for easy transport and storage.
