  • Reduced Handle Effort – The P77 is engineered with an optimized lever ratio that significantly minimizes input force, enabling smoother operation with less physical exertion.

  • Ergonomic Grip – The contoured, non-slip handle grip reduces hand strain and enhances comfort, substantially decreasing operator fatigue during extended or repetitive use.

  • The integrated two-speed pumping mechanism automatically shifts from high-flow, low-pressure stroke to low-flow, high-pressure stroke, ensuring rapid tool advancement and quick system pressurization with minimal manual effort.

  • Vent-Free Reservoir – The sealed, vent-free oil reservoir eliminates the risk of fluid spills, leaks, and contamination, ensuring a clean, safe working environment even in awkward or overhead orientations.

  • Integral Over-Pressurization Protection – Built-in internal relief protection safeguards the pump and downstream hydraulic components from damage caused by excessive pressure build-up.

  • All-Steel Construction – The heavy-duty steel body provides exceptional impact resistance and structural integrity for the toughest job sites.

  • Chrome-Plated Plunger & Wiper System – The corrosion-resistant, chrome-plated plunger, combined with an advanced wiper seal, effectively excludes dirt, moisture, and debris, ensuring consistent performance, extended seal life, and reliable operation in contaminated or outdoor environments.

  • Quick-Grip Handle – The integrated carry handle offers a secure, comfortable grip for effortless transport and positioning, making the P77 ideal for field service, maintenance, and mobile repair operations.
