Reliable operation up to 1500 bar, suitable for heavy-duty bolt tensioning applications.
Fast fill at low pressure, precise control at high pressure.
Offers the right drive-type choice based on field conditions and workload.
Glycerin-filled gauge provides instant, vibration-free readings.
Lightweight body and carry handle suited for field use.
Ensures pressure and connection compatibility with Hydro Bard bolt tensioning cylinders.
It generates the high-pressure oil required to operate bolt tensioning cylinders and hydraulic nuts.
The manual pump operates by hand-lever force, while the air-driven pump runs on a compressed air supply; the air-driven type saves time on higher-volume or repetitive jobs.
It is designed to operate in the 1500 bar (21,750 PSI) class.
It can be used with HRT series bolt tensioning cylinders and compatible hydraulic nuts via the STFC4 quick coupling.
The first stage delivers a fast oil fill, while the second stage provides precise approach to the target pressure.
A minimum 7 bar air supply pressure and, depending on the model, 28–56 scfm air consumption are required.
It can be used across a wide range of applications, including field sites, workshops, offshore, and energy facilities.
The integrated glycerin-filled pressure gauge provides vibration-free, instant pressure monitoring.
As standard, it operates safely within an ambient temperature range of −20°C to +50°C.
Regular oil level checks and the use of clean hydraulic oil are sufficient; no special maintenance equipment is required.
Using it together with a high-pressure hose, a pressure gauge, and, if needed, a hydraulic manifold is recommended.
