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.
Reliable, efficient, and easy to maintain- Gorman-Rupp self-priming pumps handle liquids containing air, solids, and debris while keeping maintenance hassle-free. Thanks to automatic repriming, they continue running even if the suction line is completely empty. Their above-ground installation ensures easy servicing, eliminating the need for confined space entry.
Designed for demanding conditions, Gorman-Rupp dry-prime pumps automatically remove air from the suction line, allowing for immediate pumping without manual priming. They deliver high flow rates, large solids handling, strong suction power, and energy-efficient operation- ideal for tough applications that require reliability and quick deployment.
For heavy-duty bentonite applications, we recommend the Gorman-Rupp S-Line or E-Line PAV4 and PAV6. This dry self-priming vortex centrifugal pump is designed for demanding jobs. The Performance+ version even delivers higher pressure compared to the standard version. These pumps perform exceptionally well in horizontal directional drilling and in temporary bypass installations.
Bentonite is viscous, abrasive, and contains fine solids. It requires pumps with strong wear resistance, stable flow, and the ability to manage pressure variations during long operating hours.
Several design elements are incorporated to reduce wear in abrasive mixtures like bentonite The vortex impeller design allows solids to pass without contacting the impeller. The thick-walled volute design with low-resistance discharge orientation further aid to the durability and reliability, as is the hydraulic design that allows low speed running even at top performance levels.
The dry self-priming capability makes it ideal for construction sites where pumps must start quickly and run reliably even under fluctuating suction conditions.
Yes, as long as the bentonite contains enough free water to remain pumpable. The pump’s vortex construction ensures smooth passage of solids and minimizes clogging.
Absolutely. It is widely used for wastewater bypassing, sludge handling, and general dewatering where extra pressure and high reliability are required.
The S-Line and E-Line mobile PAV pumps has a service-friendly design. Internal components are easily accessible, which shortens maintenance time and keeps operations running.
Yes. All S-Line diesel driven version are designed to run on HVO100 fuel, providing ISCC certified CO2 saving up to 89%. For complete emission free on-site application, Gorman-Rupp Offerte the E-Line electric driven mobile pumps. Fewer Emission, more impact. Ready for tomorrow.
Yes. Through ArchyRental, this pump is available for short-term and long-term rentals, including support with sizing, delivery, and installation.
