High Pressure Hand Grease Pump (700bar)
Achieving precise lubrication in heavy-duty industrial environments requires more than just standard equipment. Our high pressure hand grease pump is engineered to deliver consistent performance up to 700 bar, ensuring that even the most stubborn seals and bearings receive the necessary lubricant. When you are dealing with high-torque applications, the ability to control pressure precisely is the difference between a well-maintained machine and a costly breakdown. This manual tool provides the mechanical advantage needed for extreme pressure tasks without requiring bulky pneumatic setups.
The design focuses on ergonomic efficiency. We know that repetitive manual tasks can lead to operator fatigue, so we optimized the lever movement to require minimal arm effort. By integrating a specialized air relief valve, the system eliminates trapped air pockets that often cause pressure fluctuations. This ensures that every stroke of the pump translates directly into useful work at the nozzle tip, making it a reliable choice for maintenance teams working in tight or remote locations.
Precision Control with Advanced Valve Technology
One of the standout features of this pressure hand grease pump is the integrated valve system. It includes a check valve, an air relief valve, and a pressure relief valve working in harmony. The check valve prevents backflow, which is essential for maintaining a steady stream of lubricant. Meanwhile, the air relief valve—a critical component for stability—allows you to purge the system of any air bubbles before you begin the high-pressure application. This prevents the “spitting” effect often seen in cheaper, non-regulated manual pumps.
The pressure relief valve serves a dual purpose. First, it protects the internal components from over-pressurization. Second, it allows for an easy and clean separation of the nozzle from the lubrication point. After you have reached the desired 700 bar, simply activating the relief mechanism ensures that the lubricant return flow from the cylinder is managed smoothly. This prevents messy leaks and keeps your workspace clean, which is a priority for any professional workshop.
High Clamping Force Without Auxiliary Equipment
In many industrial scenarios, applying high pressure to studs or bolts requires secondary hydraulic jacks or heavy-duty clamps. Our pump changes that dynamic. It produces high clamping force through its internal hydraulic design, meaning you can achieve significant torque or seating force without needing auxiliary force from external tools. This makes it an incredibly versatile asset for field service engineers who cannot carry heavy hydraulic power packs.
The 400-500 cm3 capacity provides enough volume for sustained work sessions. Whether you are working on large-scale industrial flanges or heavy machinery components, the pump maintains a stable reservoir. The pressure gauge is not just a secondary feature; it acts as your primary control tool. It allows for the precise monitoring of pressure build-up, which is vital when you are tightening studs or ensuring that a seal is seated perfectly under controlled tension.
Technical Specifications and Performance Limits
Understanding the operational limits of your equipment is key to safety and longevity. This pump is specifically designed for high-pressure environments where standard grease guns fail. The application pressure range is strictly defined to ensure optimal performance and safety for the operator.
- Maximum Operating Pressure: Up to 700 bar for extreme-duty applications.
- Minimum Effective Pressure: Starts reliably from 300 bar.
- Reservoir Capacity: 400-500 cm3 for efficient, continuous use.
- Integrated Safety: Features a dedicated pressure relief valve to prevent surges.
Operating the pump below 300 bar is possible, but the tool is optimized for the 300 to 700 bar range. Exceeding the 700 bar limit is not recommended, as the structural integrity of the manual seals is calibrated for this specific threshold. Using the tool within its intended bar range ensures that the air relief mechanism and the check valve function with maximum precision.
Applications in Heavy Industry
Where can you use a 70 lubricated hand pump? The possibilities are vast, particularly in sectors like mining, oil and gas, and heavy manufacturing. Any scenario involving high-pressure grease injection or the controlled tightening of heavy-duty fasteners benefits from this tool. It is particularly useful for maintenance of large-diameter bolts where even pressure distribution is mandatory to prevent uneven loading.
We often see this pump used in:
- Hydraulic system maintenance where precise grease injection is required.
- Stud and bolt tensioning applications requiring controlled pressure build-up.
- Sealing element installation where high clamping force is necessary for a leak-proof fit.
- Remote field repairs where pneumatic or electric pumps are unavailable.
Comparison: Manual Hand Pump vs. Standard Grease Guns
Many technicians mistakenly attempt to use standard pneumatic or battery-operated grease guns for high-pressure tasks. However, the physics of a 700 bar requirement are much more demanding than standard lubrication. Below is a comparison to help you decide if this specialized tool is necessary for your specific task.
| Feature | Standard Grease Gun | High Pressure Hand Pump (700bar) |
|---|---|---|
| Max Pressure Capability | Typically 300-500 bar | Up to 700 bar |
| Air Management | Minimal air relief | Integrated air relief valve |
| Precision Control | Difficult to regulate | High precision via pressure gauge |
| Clamping Force | Low | High (Internal hydraulic design) |
Maintenance and Long-Term Reliability
To ensure your pressure hand grease pump remains a reliable part of your toolkit, regular maintenance is essential. While the tool is built for rugged use, the seals and valves are sensitive to contamination. Always ensure that the grease used is clean and free of debris. If you notice any drop in pressure or difficulty in the air relief process, inspect the check valve for any particulate matter that might be obstructing the flow.
We recommend cleaning the nozzle area after every use. Because the pump features a lubricant return flow, any dried grease can accumulate around the relief valve. Keeping this area clear ensures that the “easy and clean separation” feature continues to work as intended. A well-maintained pump will easily last for years, providing the 700 bar performance you rely on for critical industrial repairs.
Frequently Asked Questions
How do I know if there is air trapped in the pump?
If you notice the pressure gauge fluctuating or the pump feeling “spongy” during operation, air is likely trapped. Use the integrated air relief valve to bleed the system. This process is straightforward and should be done before you begin any high-pressure application to ensure accuracy.
Can this pump be used with any type of lubricant?
While the pump is versatile, we recommend using high-quality industrial lubricants that are compatible with high-pressure environments. The viscosity of the lubricant can affect the efficiency of the air relief and the pressure build-up. Always check the compatibility with your specific application requirements.
Is the 700 bar pressure safe for manual operation?
Yes, provided the operator follows standard safety protocols. The pump is designed with a pressure relief valve specifically to prevent accidental over-pressurization. The ergonomic design also ensures that the force required is manageable for a trained professional.
