Comprehensive Guide to Greasing Pedrollo Pump Systems: Structure, Types, Applications, and Benefits
Greasing/Lubrication Pump Systems, an Overview.
A lubrication pump plays a vital role in keeping machinery operating efficiently. Its main function is to circulate oil from a storage reservoir to various components within the equipment, especially those prone to friction like bearings and moving joints. By generating enough pressure, the pump ensures that oil reaches these areas consistently and in the right amounts.
This process helps minimize wear and tear, enhances performance, and extends the overall lifespan of the machine. Lubrication pumps are available in both manual and automatic models, offering flexibility based on the specific needs of the equipment or industry.
To maintain oil quality, the pump draws lubricant through a wire mesh strainer that captures larger particles or debris. Afterward, the oil passes through a cooling system and a secondary filter, ensuring it’s clean and at an optimal temperature before reaching critical parts such as valve stems, pistons, springs, and rings.
Regular lubrication using a high-quality pump is a key aspect of preventive maintenance and reflects best practices for keeping machinery in top condition.
Greasing Pedrollo pump system company is a grease lubrication electric pump manufacturing company which has been manufacturing the grease lubrication pumps since the 1900s and has become a top exporter worldwide. Pedrollo pumps are known for their efficiency and reliability and are used in various applications, including domestic water supply, irrigation and industrial water transfer. Hence Pedrollo is typical in municipal, domestic, agricultural, and industrial jet pumps.
Structure/Composition of Greasing Pedrollo Pump.
A well-designed lubrication pump system is essential for ensuring the long-term performance and reliability of mechanical equipment, especially in demanding environments like gas compression systems. These systems typically consist of injectors, metering valves, feed lines, a central pump, and a reservoir that stores and distributes grease or oil to critical components such as bearings and crosshead shoes.
Lubrication pumps can be operated manually or controlled via automated systems. When integrated with a control panel through a switch, an auto-lubrication pump unit simplifies maintenance and improves consistency. Brands may vary in design, but the core function remains the same: circulating grease or oil efficiently to components like the cylinder lubrication system and rod bearings.
In industrial applications, forced-feed lubrication pump systems are best suited for high-demand operations like oilfield gas compression. These systems rely on a pump to move lubricant through filters and coolers before delivering it to the bearings. Splash lubrication systems, on the other hand, are more cost-effective and ideal for smaller air compressors. These systems use an oil ring that rides loosely on a rotating shaft, dipping into the lubricant sump and distributing grease along the shaft through centrifugal motion.
For optimal performance, the main oil pump should be capable of handling at least 110% of the maximum expected flow, based on crankshaft pressure. To maintain consistent pressure, an auxiliary pump—powered by an electric motor—should automatically activate if supply pressure falls below a set minimum. A pre-lube pump, whether automatic or manual, prevents dry running by ensuring that oil is circulated before startup.
Temperature control is critical. The oil cooler should handle at least 110% of the estimated maximum thermal load, maintaining oil temperatures below 165°F. Air coolers may use shell-and-tube designs with air-cooled or jacket-cooling configurations to ensure efficient heat dissipation.
Oil filtration varies depending on the lubrication pump manufacturer. Systems may include full-flow or dual-flow filters, often equipped with isolation valves to prevent low-pressure shutdowns. An overhead day tank should have a clear level indicator and be large enough to store sufficient oil for continuous operation.
Material selection for piping is another vital consideration. Carbon steel pipes are often coated and treated with a rust inhibitor for durability, while all pipes downstream of filters should be stainless steel and free of galvanizing. Careful welding and design practices prevent dirt accumulation and ensure clean lubrication flow, which can pass through a 200-mesh screen.
The dry gas seal is a key component in modern electric lubrication pump systems, offering a reliable sealing solution for centrifugal compressors . These seals are typically managed by control panels that include alarm and shutdown features for added safety.
Lastly, the system’s axial thrust bearings usually come with one proximity probe pre-installed, with the option to add a second. Temperature sensors vary by brand, and while many modern systems include sophisticated monitoring, not all have built-in alarms—something to consider when evaluating different lubrication pump solutions.

Working Principle of the Greasing Pump.
A lubrication pump plays a vital role in distributing oil effectively to mechanical components, ensuring smooth operation and reducing wear. In many systems, an AC-powered grease lubrication pump is installed on top of the oil tank and is connected through a filter located at the bottom. This setup allows the pump to draw oil from the inlet pipe, using a bearing in the primary oil line to support efficient drainage.
The system is typically equipped with a pressure control switch to regulate oil flow, while a flap check valve at the outlet prevents backflow—ensuring consistent lubrication without contamination or loss of pressure.
The performance of a centralized lubrication pump can vary depending on the oil’s viscosity, which directly affects flow rate and pump efficiency. Inside the pump, key components include couplings, mechanical and packing shaft seals, a shaft, bearings, gears, and both front and back covers—all housed within a durable pump body.
This pump is engineered to deliver clean, steady oil to gear bearings at the correct flow rate, temperature, and pressure. It uses a meshing wire gear mechanism that allows the gear teeth to rotate, disengage, and then re-engage with the pump body. As the gear teeth exit the suction chamber, the chamber’s volume increases and pressure decreases, drawing oil in.
Once inside, the oil is carried to the discharge chamber, where the volume decreases and pressure increases—forcing the oil out of the pump. This controlled process ensures reliable and efficient lubrication, which is essential for extending the lifespan of mechanical systems and maintaining optimal performance.
Understanding these core principles is key to selecting and maintaining a lubrication pump that meets your specific operational needs. Whether for industrial machinery, automotive systems, or manufacturing equipment, the right pump can make a measurable difference in performance, maintenance costs, and equipment longevity.

Historical Overview of Lubrication Pumps.
The history of lubrication pumps stretches back more than 3,500 years, to around 1400 B.C., when early vehicles like chariots, carts, and wagons first appeared. These early machines required a way to keep their wooden wheels turning smoothly, especially as friction from use would cause the wheel hubs to heat up and even burn. To solve this, people began applying lubricants to reduce heat and wear—initially using natural substances like animal fats and olive oil.
As time went on, the need for more effective lubrication methods led to the development of mechanical solutions. The introduction of the grease pump marked a major step forward, replacing rudimentary methods like pouring oil from cups. This shift not only made lubrication easier but also significantly improved efficiency and equipment longevity.
In 1918, Arthur Gulborg revolutionized machinery maintenance with the invention of the grease gun—an early lubrication pump that used a nozzle to apply grease directly to moving parts. His innovation included the use of compressed fittings, which made the process cleaner, more precise, and less wasteful.
Just a few years later, in the 1920s, Oscar Ulysses contributed further advancements by improving the pump nozzle design. His enhancements ensured a tighter fit, introduced locking connections, and incorporated manual triggers, all aimed at improving grease flow control and reducing leaks. These early inventions laid the foundation for the modern lubrication systems we rely on today, proving that even ancient challenges can inspire innovations that stand the test of time.

Understanding the function of each component in a lubrication system is essential for effective maintenance and troubleshooting. Whether you’re replacing a worn-out part or upgrading your system, using high-quality, manufacturer-approved spare parts will ensure continued reliability and performance.
Understanding the Lubrication Pump Control Systems.
Lubrication pump control systems can be classified in several ways — by how they distribute lubricant, how they regulate the volume delivered, and the type of lubricant used. Each system is designed with specific applications in mind to ensure reliable and efficient performance.
Oil-based lubrication systems are commonly found in stationary equipment such as CNC milling machines and industrial machinery, where precise and consistent lubrication is critical. On the other hand, grease lubrication systems are better suited for mobile or heavy-duty equipment — think construction vehicles, mining equipment, and transport trucks — where components are exposed to harsh environments and require thicker lubricants.
Choosing the right type of lubricant isn’t just about the machine — it’s about the conditions it operates in. Key factors to consider include operating temperature, the length and diameter of the feed lines, and the viscosity of the lubricant. These variables directly impact how effectively the lubricant can flow through the system and reach critical components.
In more demanding environments, systems using positive displacement injectors and pressure relief valves offer precise control. These systems rely on a piston mechanism to deliver an exact amount of lubricant, making them ideal for high-performance applications where accuracy and reliability are non-negotiable.
Exploring Resistant and Automatic Lubrication Control Systems.
Lubrication systems play a vital role in keeping industrial and mobile equipment running smoothly, minimizing wear, and ensuring long-term reliability. Among these systems, resistant lubrication control systems and automatic lubrication systems offer various configurations to suit different operational needs.

- Mist Lubrication Systems – Common in high-speed machinery, creating a fine mist for minimal, yet effective, lubrication.
- Single-Line Systems
- Single-Line Parallel Systems
- Dual-Line Parallel Systems
Each of these offers distinct benefits depending on the equipment and lubrication needs.
Single-Line Systems.
In a single-line system, the flow of lubricant controls a sequence of valve assemblies and metering devices. These valves cycle the pistons inside cylinders — pushing them forward to dispense lubricant and trigger the next piston in line. This method ensures a controlled, consistent output, and in many setups, the pistons can be pre programmed for a fixed volume, ensuring uniform lubrication every cycle.
Single-Line Parallel Systems.
This system delivers grease using hydraulic pressure to serve multiple lubrication points simultaneously. Though powered by a single lubrication pump, the system supports multiple injector units, each calibrated to release varying amounts of lubricant based on specific zone requirements. It’s ideal for machines that demand different volumes of grease across components.
Dual-Line Parallel Systems.
Built for large-scale or heavy-duty applications, dual-line parallel systems operate by alternating two main lines between pressurizing and venting cycles. This alternating flow helps deliver precise amounts of lubricant to a vast number of distribution points — often over a hundred — using just one centralized pump. It’s a cost-effective solution that supports extensive lubrication networks with smaller diameter feed lines.
Multipoint Lubrication Systems.
Multipoint systems offer a more compact and automated solution. They typically use a cam mechanism and a drive motor to activate injectors that deliver lubricant to each point. Designed for ease of use, these systems require fewer accessories and operate with minimal manual oversight, making them perfect for consistent and simplified lubrication tasks.
Installation Procedure of Lubrication Pump.
Installing a lubrication pump correctly is essential to ensuring the long-term efficiency and reliability of your equipment. A well-executed installation not only helps extend the lifespan of the pump itself but also plays a crucial role in maintaining smooth production operations.
While grease lubrication pumps are generally easy to install, enlisting expert guidance can help you avoid common mistakes and optimize the system for your specific application. Before getting started, it’s important to understand the key benefits of using a lubrication pump—such as minimizing equipment wear, reducing unscheduled downtime, and improving overall operational efficiency.
Proper installation sets the foundation for precise lubricant delivery, which directly impacts machine performance and longevity. In the following section, we’ll walk through the essential steps for installing a grease lubrication pump, ensuring your setup supports long-term success and reliability.
Proper planning and careful execution are essential for successfully installing a lubrication pump system. A well-designed setup not only boosts operational efficiency but also extends the lifespan of your equipment by ensuring consistent, targeted lubrication.
1. Planning the Installation.
The first and most important step is developing a thoughtful installation plan. This involves identifying the ideal location for the lubrication pump and ensuring the system can easily reach all critical lubrication points. Consulting with a trusted lubrication pump manufacturer at this stage is highly recommended—they can help you select the right system and configuration based on your equipment and operating environment.
2. Positioning the Pump and Reservoir.
Once you’ve assessed the layout, install the reservoir and lubrication pump in a location that allows for easy maintenance and access to control components, such as the motherboard. Secure the pump firmly to the reservoir to reduce vibrations and movement during operation. Gravity-fed setups can be particularly effective, as they help ensure smooth lubricant flow.
3. Installing Tubing.
Next, connect the pump to the lubrication points using durable, flexible tubing. Choose tubing that can withstand pressure and environmental demands. To prevent damage or performance issues, use mounting brackets to secure the tubes and avoid sharp bends or kinks. Keeping the tubing as short and straight as possible helps reduce pressure loss and improve system efficiency.
4. Connecting Fittings.
Attach the appropriate fittings to each lubrication point. These connectors link the tubing to specific parts of your equipment, ensuring accurate lubricant delivery. Use thread sealants or tape to secure all fittings and prevent leaks, maintaining a sealed and reliable flow path.
5. Setting Up the Control Unit.
Mount the control unit in a visible, easily accessible location for monitoring and adjustments. This component manages the timing and volume of lubricant released, allowing you to tailor the system to your machinery’s needs. Be sure to configure the pump’s settings—such as lubrication intervals and output volume—based on the manufacturer’s recommendations and your operational requirements.
6. Testing the System.
Before putting the system into full operation, perform thorough testing to check for leaks, blockages, and proper lubricant flow. Confirm that the lubricant is reaching all designated points at the correct rate. If needed, fine-tune the settings to optimize performance and ensure consistent, effective lubrication.
Maintenance Procedure of the Lubrication Pump.
Routine maintenance is essential to keep your lubrication pump functioning efficiently and to prevent unexpected downtime. By following a consistent maintenance schedule, you can ensure reliable lubricant delivery, extend the system’s lifespan, and reduce costly repairs.
Below are key tips to help you properly maintain your lubrication pump system:
1. Regular Cleaning and Inspection.
Keeping your lubrication pump clean is one of the simplest yet most effective ways to maintain optimal performance. Dust, debris, and material buildup can interfere with the pump’s operation, so it’s important to clean external surfaces regularly. Routine visual inspections also help identify early signs of wear, blockages, or system faults before they escalate into major issues.
2. Perform Operational Checks
Consistent performance checks are crucial. Monitor the pump’s output, pressure, and placement during operation to ensure it’s supplying the correct amount of lubricant to each point. Keep an eye out for irregularities such as excessive vibration, pressure drops, or inconsistent flow—all of which can indicate mechanical issues that need attention.
3. Monitor Fluid Levels and Replace When Needed
Check reservoir levels frequently and top up when necessary. Always use the manufacturer-recommended lubricant and be mindful of the oil type in use. For mineral-based oils, plan for an oil change every six months. If you’re using high-quality synthetic lubricants, the interval can often be extended to up to 24 months. This helps preserve system integrity and performance over time.
4. Lubricate Moving Parts
Ironically, even lubrication pumps require lubrication. The internal mechanical components—such as gears, pistons, and drive mechanisms—should be lubricated as specified by the manufacturer. Regular lubrication minimizes friction, reduces wear, and helps prevent mechanical failure.
5. Check Fittings, Tubing, and Vents
Inspect fittings and tubes for signs of leaks or damage. Replace any worn components promptly to maintain airtight connections and efficient flow. Additionally, ensure breather vents are equipped with guards to prevent contamination from entering the system, especially in dusty or high-debris environments.
By following these maintenance practices, you not only keep your lubrication pump running efficiently but also protect your entire machinery system from premature wear and costly breakdowns.
