HDD

HDD, or Horizontal Directional Drilling, is an advanced technique for installing underground pipes and conduits without breaking ground surfaces. This minimizes disruptions such as road closures or detours.

With increasing investment in underground infrastructure, HDD is a rapidly growing technology that requires high-quality pumps for various applications.

Gorman-Rupp provides the right pumps for the job. HDD drilling uses a specially formulated drilling fluid called bentonite, a clay-like substance that lubricates drilling and reaming processes while facilitating the installation of pipes and cables.

Gorman-Rupp pumps are essential at both the entry and exit pits of HDD operations. Medium head pumps return bentonite to the recycling plant, while high-head booster pumps transport bentonite over long distances from the exit pit.

HDD applications push both equipment and operators to their limits. Pumps must resist abrasion, handle varying loads and intermittent flows, and efficiently process high-viscosity drilling slurries.

That’s why HDD operators rely on Gorman-Rupp. Our HDD bentonite pumps are a proven solution for these demanding applications.

Gorman-Rupp HDD bentonite pumps are available with a modern, eco-friendly Stage 5 diesel engine for quick deployment on-site or an emission-free electric drive. Whatever your requirements, Gorman-Rupp has the right HDD bentonite pump for you.
