Pump-in Subs

Standard or Custom Design Pump-In subs

Basic design

  • The installation location is customer dependant, but its uses are fairly common and straight forward.
  • The Pump-in sub allows for well control by providing a port to "pump-in" fluids.
  • Another common use is a fluid sampling port. The port connection is a type-W compatible hammer union (integral, or thread-in).
  • The fact that the upper and lower union combinations are built to your request makes the pump-in sub a perfect connection cross-over point.
  • 15,000 psi. working pressure
  • 22,500 psi. test pressure
  • H2S service compatible


Pressure and service, dependant on union requested.
