The next evolution in wellhead efficiency

Built for efficiency. Designed for speed.

All the proven efficiency of the DMLX — now optimized for faster rig time and reduced height. See what makes the DMLX-S tick with our enhanced new opportunity to explore the system through Stream-Flo’s guided 3D Virtual Stack-Up Experience.

Designed for speed and simplicity

The DMLX-S is engineered to deliver measurable rig-time efficiency without compromise. With torque-through mandrels for rotation below the rig floor and a reduced overall height that lowers cellar and installation costs, it’s designed for performance on today’s multi-well pads.

Highlights:

  • Reduced height = smaller footprint and cost savings

  • Offline cementing enables faster well completion

  • Quick-connects and torque tools streamline make-up and testing

The Virtual Stack-Up Experience

See the DMLX-S system come to life through Stream-Flo’s guided 3D Virtual Stack-Up Experience.

Our team uses a real-time simulation to walk you through a complete installation — including assembly, offline cementing, and running tools — so you can understand how the system integrates with your operations.

This private demonstration helps your team save time, plan ahead, and make informed technical decisions — all without a field setup.

Key Benefits:

  • Exclusive, engineer-guided experience

  • Real-time 3D visualization of your full installation

  • Includes offline cementing, running tools, and assembly steps

  • Saves time and cost by allowing virtual pre-planning

  • Controlled access ensures proprietary system details remain secure

Modular by design

From solid to fluted to contingency mandrels, the DMLX-S provides seamless adaptability across a range of applications.

Standardized, torque-through components simplify operations and inventory management, while maintaining Stream-Flo’s reputation for reliability and integrity.

Options Include:

  • Fluted Mandrel: Full annular cement returns and pressure balance

  • Solid Mandrel: One-trip seal with torque-through rotation

  • Contingency Mandrel: Backup for emergency or TD challenges

Proven Stream-Flo reliability

With internal latch design, metal-to-metal CSBS sealing, and fully torque-through mandrel hangers, the DMLX-S maintains integrity under high-pressure, high-temperature conditions.

Backed by Stream-Flo’s field service teams and engineering expertise, it’s performance you can depend on.
