3715B UNx Fluid End Upgrade - #11 Plungers

Part No: 52235

Increase productivity and reduce operating cost with a UNx® Fluid End Upgrade. Flow up to 26.6 gpm (101 l/min) at 12,000 psi (825 bar). Designed to fit Butterworth L-375, Gardner-Denver TF-375, and others.

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
  • 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

UNx Conversion Video

This video highlights the ease of maintenance and pressure convertibility of Jetstream UNx Pump. (3:59)

15K 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.  15,000 psi (1000 bar).  Pump-mounted.

15K Handle-Adjustable Regulator

Maintains constant system pressure when operating one or more shut-in devices. Knob-adjustable. Field-replaceable valve cartridge. For operation at 5,000 - 15,000 psi (350 - 1000 bar). Pump-mounted.
