Reliable lubrication is essential for keeping industrial machinery running efficiently. When bearings, gears, linear guides, chains, slides, and other moving components operate under continuous load, the right lubrication equipment helps deliver the correct amount of oil or grease at the right time and pressure.
At BAOTN, we have focused on electric lubrication pumps and centralized lubrication solutions for industrial applications. Through years of experience in lubrication system design, we understand that selecting lubrication equipment is not simply about choosing a pump. The pump, distributor, controller, pipeline, lubricant, and lubrication points all need to work together as a complete system.
In this guide, we explain the main types of lubrication equipment, how they work, and how to select the right solution for your machinery.
What Is Lubrication Equipment?
Lubrication equipment refers to the components used to store, transport, meter, distribute, and control lubricants throughout a machine.
A typical automatic lubrication system may include:
The primary objective is simple:
Deliver the right lubricant, in the right quantity, to the right lubrication point, at the right time.
For machines with multiple lubrication points, centralized lubrication equipment allows one lubrication system to serve multiple components. This can reduce manual maintenance and provide more consistent lubrication.
Why Is Lubrication Equipment Important?
Inadequate lubrication can result in increased friction, component wear, overheating, and unexpected equipment downtime.
Properly selected lubrication equipment helps us address several common maintenance challenges.
Reduce Friction and Component Wear
A suitable lubricant creates a protective film between moving surfaces. Automatic lubrication equipment helps maintain an appropriate lubricant supply during machine operation.
Maintain Consistent Lubrication
Manual lubrication depends on maintenance schedules and operator practices. Automatic lubrication equipment can deliver lubricant according to a preset cycle, helping maintain more consistent lubrication.
Reduce Manual Maintenance
Centralized lubrication allows multiple lubrication points to be supplied from a central pump. This is particularly valuable when lubrication points are difficult to access or located inside complex machinery.
Improve Lubricant Utilization
Accurate metering helps prevent excessive lubrication while ensuring that critical components receive sufficient lubricant.
Support Equipment Reliability
Consistent lubrication can help reduce lubrication-related failures and contribute to more stable machine operation.
Main Types of Lubrication Equipment
Different machines require different lubrication methods. When we select lubrication equipment, we normally consider the lubricant type, number of lubrication points, required pressure, lubricant volume, operating environment, and automation requirements.
The main categories include:
Electric grease lubrication pumps
Electric oil lubrication pumps
Progressive lubrication equipment
Volumetric lubrication equipment
Oil-air lubrication equipment
MQL lubrication equipment
Lubrication distributors
Controllers and monitoring components
Let's look at the main applications in more detail.
Electric Grease Lubrication Equipment
Grease is commonly used for bearings, bushings, pins, gears, linear guides, and other components operating under load.
An electric grease lubrication system generally consists of:
Electric Pump → Main Pipeline → Distributor → Branch Pipelines → Lubrication Points
The electric pump supplies grease from the reservoir, while the distributor controls how grease is delivered to individual lubrication points.
When we design a grease lubrication system, we consider:
For high-pressure applications, our GET High-Pressure Lubrication Pump is designed for progressive centralized lubrication systems and can support pressures up to 35 MPa.
If your application requires high-pressure grease delivery, learn more about our GET High-Pressure Lubrication Pump and review the technical specifications.
Progressive Lubrication Equipment
Progressive lubrication systems are particularly useful when one pump needs to supply multiple lubrication points.
The basic operating structure is:
Pump → Main Distributor → Progressive Distributor → Lubrication Points
A progressive distributor sequentially distributes lubricant to different outlets. This allows us to build a centralized lubrication system according to the number and arrangement of lubrication points.
Progressive lubrication equipment can be used for:
When we design a progressive system, we consider the number of lubrication points, lubricant consumption, pump capacity, distributor configuration, and pipeline layout together.
Automatic Grease Lubrication Systems
Automatic grease lubrication equipment eliminates the need to manually lubricate every lubrication point.
A typical automatic system can include:
Grease pump
Reservoir
Controller
Progressive distributor
Pipes
Fittings
Pressure monitoring
Low-level monitoring
The controller can activate the pump according to a predetermined lubrication cycle.
This approach is especially useful when machinery:
Operates continuously
Contains many lubrication points
Requires frequent lubrication
Has difficult-to-access lubrication points
Operates in dusty or harsh environments
Requires automated preventive maintenance
Our approach is to configure the pump, distributor, controller, and pipeline as one complete system rather than treating each component separately.
Volumetric Lubrication Equipment
Volumetric lubrication systems are designed to deliver a predetermined amount of lubricant to each lubrication point.
This makes volumetric systems suitable for applications where precise and repeatable lubricant quantities are important.
A typical system can include:
Lubrication pump
Filter
Distribution block
Volumetric distributors
Pipes
Fittings
When selecting this type of equipment, we pay particular attention to the required lubricant volume at each lubrication point and the operating cycle of the machine.
Oil Lubrication Equipment
Grease is not suitable for every application. High-speed bearings, machine tools, spindles, and other components may require lubricating oil because of its flow characteristics and ability to assist with heat dissipation.
Oil lubrication equipment can include:
When we select an oil lubrication system, we consider:
Oil-Air and MQL Lubrication Equipment
For high-speed and precision applications, oil-air and minimum quantity lubrication systems provide another approach to lubricant delivery.
These systems deliver a controlled amount of lubricant, often together with compressed air, to the required lubrication area.
Potential applications include:
High-speed spindles
Machine tools
High-speed bearings
Precision machining
Cutting operations
The appropriate configuration depends on spindle speed, lubricant viscosity, air pressure, lubricant flow, and machining conditions.
How to Choose the Right Lubrication Equipment
Choosing lubrication equipment based only on pump pressure or reservoir capacity can lead to an unsuitable system.
We recommend evaluating the entire lubrication application.
Identify the Lubricant
First determine whether the machine uses:
Oil and grease have different flow and pumping characteristics, so the lubrication equipment needs to be matched to the lubricant.
Determine the Number of Lubrication Points
Count all lubrication points that need to be supplied.
A machine with several lubrication points may only require a relatively simple system, while a large industrial machine with dozens of points may benefit from a centralized progressive or volumetric lubrication system.
Calculate the Required Pressure
Required pressure depends on:
The pump must be capable of supplying sufficient pressure throughout the entire lubrication circuit.
Determine Lubricant Consumption
We need to understand how much lubricant each lubrication point requires and how frequently it needs to be lubricated.
The pump displacement and operating cycle can then be selected accordingly.
Too little lubricant can cause inadequate lubrication, while excessive lubricant can increase consumption and potentially create problems for certain components.
Determine the Required Automation Level
Consider whether the system requires:
For automated production equipment, PLC-compatible lubrication equipment can simplify integration with the machine control system.
Evaluate the Working Environment
Environmental conditions can significantly influence lubrication equipment selection.
We normally evaluate:
The equipment should be selected according to the actual working environment rather than laboratory conditions.
Lubrication Equipment vs. a Complete Lubrication System
One of the most important concepts we emphasize is that a lubrication pump is only one part of a lubrication system.
A complete system may include:
Reservoir + Pump + Controller + Distributor + Pipeline + Fittings + Sensors + Lubrication Points
For example, selecting a high-pressure pump does not automatically guarantee that every lubrication point will receive the required amount of grease.
The distributor, pipeline diameter, pipeline length, grease characteristics, and lubrication cycle also affect system performance.
That is why we recommend designing the lubrication system according to the complete machine configuration.
Common Lubrication Equipment Problems
Even when the equipment itself is correctly selected, improper installation or maintenance can affect performance.
Insufficient Lubricant Delivery
Possible causes include:
Excessive Lubricant Consumption
Possible causes include:
Incorrect metering
Excessive lubrication frequency
Incorrect pump displacement
Leakage
Incorrect distributor selection
Lubrication Pressure Cannot Be Established
When pressure cannot be established, we recommend checking:
Lubricant level
Pump operation
Pipeline connections
Distributor condition
Pressure setting
Air inside the lubrication circuit
Leakage at fittings
For grease systems, proper filling and air removal are particularly important because air entering the pump chamber can result in weak or intermittent grease delivery.
Our Approach to Lubrication Equipment Selection
At BAOTN, we approach lubrication equipment from a complete-system perspective.
Instead of asking only:
"Which lubrication pump should I use?"
we recommend starting with:
"What lubrication system does my machine actually require?"
We evaluate:
Based on these factors, we can determine whether an electric oil pump, electric grease pump, progressive lubrication system, volumetric system, or another configuration is more appropriate.
Frequently Asked Questions About Lubrication Equipment
What is lubrication equipment used for?
Lubrication equipment is used to store, transport, meter, distribute, and control lubricating oil or grease so that machine components receive the required lubricant.
What is the difference between oil and grease lubrication equipment?
Oil lubrication equipment is designed for liquid lubricants, while grease lubrication equipment must handle higher-viscosity lubricants. Pump design, distributor selection, pressure requirements, and pipeline configuration can therefore be different.
Can one lubrication pump supply multiple lubrication points?
Yes. A centralized lubrication system can use one pump together with distributors and pipelines to supply multiple lubrication points.
How do I choose lubrication equipment for industrial machinery?
Start by identifying the lubricant, number of lubrication points, required lubricant quantity, pressure, lubrication frequency, pipeline configuration, working environment, and automation requirements.
Can lubrication equipment be integrated with a PLC?
Yes. Many industrial electric lubrication pumps can be integrated with machine control systems through external control interfaces. The specific control method depends on the pump model and system configuration.
Conclusion
Choosing the right lubrication equipment is essential for maintaining reliable industrial machinery.
An effective lubrication solution should not be selected according to pump specifications alone. The lubricant, pump, distributor, pipeline, controller, lubrication points, operating conditions, and lubrication cycle all need to be considered as one complete system.
Whether you need an electric grease pump, oil lubrication equipment, progressive lubrication system, volumetric lubrication system, or a customized centralized lubrication solution, we recommend starting with the actual operating requirements of your machinery.
