Gruvmaster Patented Hydraulic Cylinder — The Core of Reliable Roll Grooving
When you look at a Gruvmaster roll grooving machine, the cylindrical part mounted beside the roller assembly is not just a housing — it’s the heart of the machine: the hydraulic cylinder.
Inside this compact, heavy-duty cylinder lies the hydraulic oil that drives the entire grooving process. Unlike many ordinary cylinders on the market that require frequent oil replacement, the Gruvmaster hydraulic system is designed for long service life — the oil can be used for two to three years without replacement, maintaining stable pressure and consistent performance.
What truly sets Gruvmaster apart is our dual-patented hydraulic technology, developed and manufactured in-house.
1.Titanseal™ Dual-Seal Design — Zero Leakage, Long-Term Stability
Traditional hydraulic cylinders often use a single-layer seal. Over time, temperature changes and high-pressure operation can lead to gradual oil leakage, reduced performance, and increased maintenance costs.
Gruvmaster’s patented Titanseal™ system features a dual-layer sealing structure, forming two independent protection zones that completely prevent oil leakage.
Even after years of heavy-duty use, the Titanseal™ maintains powerful and stable hydraulic pressure — ensuring reliability in every groove.
2.One-Push™ Ultra-Fast Feeding — Efficiency in a Single Press
In most roll grooving machines, engaging the groove roller with the pipe requires multiple manual adjustments. Gruvmaster revolutionized this process with the One-Push™ system — a single-press hydraulic engagement that instantly feeds the roller to the pipe.
This innovation not only improves operating efficiency but also ensures uniform pressure and consistent groove depth, giving professional users both speed and precision in one motion.
Summary:
At present, the TitanSeal™ dual-seal hydraulic system and One-Push™ fast-feeding system are standard features on Gruvmaster’s flagship model, the RG-8X, and both technologies are patent-pending.
In the future, these innovations will be gradually introduced to other mid- and high-end models within the Gruv-X series.
