How Does a Pneumatic Grease/Oil Pump Work?
A pneumatic Grease/Oil Pump is a lubrication system designed based on the principles of pneumatics. It converts air pressure into mechanical energy to drive a pump that delivers grease or oil steadily to the critical components of machinery. Its operation process is as follows:
- Supplied compressed air from an air compressor is directed into the pneumatic cylinder inside the machine.
- The piston inside the pneumatic cylinder is driven by air pressure to perform a reciprocating motion.
- The piston drives the pump, which draws lubricant from the oil drum and delivers it to the target location.
- The output volume and pressure can be precisely adjusted through the pneumatic valve.
The pneumatic Grease/Oil Pump features a simple and durable design, making it suitable for various industrial, maintenance, and automated machinery lubrication needs.

How to Choose the Right Pneumatic Grease/Oil Pump?
Choosing a pneumatic grease/oil Pump is much like picking the perfect assistant for your daily operations—it should match your work environment and make maintenance faster and more efficient. Here are a few common scenarios to help you quickly find the most suitable model:
1. What Type of Lubricant Are You Using?
If you're primarily dispensing grease (NLGI grade 0 to 2), it's recommended to choose a pneumatic grease pump or a manual grease pump.
Need to inject engine oil or gear oil? Choose a pneumatic oil pump, and select the appropriate model based on the SAE viscosity grade (ranging from 0 to 200).
2.How to choose based on on-site usage scenarios and space?
If you frequently require large amounts of lubrication—such as in factories or maintenance centers—a high-capacity model designed for 50-gallon (200L or 180kg) drums is the ideal choice.
For routine maintenance, mobile repairs, or limited workspace, opt for a compact 5-gallon (16–20L) unit—it’s easy to move and highly flexible.
3. Long Piping? High Pressure Requirements?
If you often need to extend the hose (over 30 feet / 9 meters) for cross-area operations, or if there are multiple machines on site, it's recommended to upgrade to a high-pressure pneumatic grease pump—such as the T-type or V-type models
4. Which Type Suits You Best?
- Pneumatic Grease Pump: Available in various capacities from 16 to 180 kg, with options like wheels and handles. Ideal for long-hour operations or environments requiring frequent movement of large drums.
- Pneumatic Oil Pump: F/J/L series models are designed for different oil viscosities. They come with a wide range of standard accessories and support diverse industrial applications.
- Manual Grease/Oil Pumps: Require no electricity or air supply, making them lightweight and portable—perfect for emergency repairs or outdoor maintenance.
- Only Need to Replace the Pump: If you already have a drum and just need a new pump unit, simply choose the corresponding model to match your existing setup.
Different models and accessories—such as hose length, trolleys, and follower plates—can all impact operational efficiency. We recommend contacting us before making a purchase so our specialists can help you plan the most suitable pump setup!

FAQ｜Answers to Common On-Site Lubrication Equipment Questions
Q: Why is my new lubricator not dispensing any oil?
A: New machines are shipped with protective plugs on the inlet and outlet ports to prevent oil leakage during transport. Please ensure these plugs have been removed before operation.
Q: Is it normal to hear a hissing sound during operation?
A: It is normal for a pneumatic lubricator to produce a hissing sound from air exhaust during operation. However, if the hissing continues after the machine stops, it may indicate that the air valve is not fully closed and requires inspection or maintenance.
Q: What are the key points for daily maintenance of a lubricator?
A:
- When not in use, always disconnect the air hose and release internal pressure. This helps protect internal components and extends the lifespan of the equipment.
- It is recommended to install a water filter on the air compressor to prevent moisture from damaging the pneumatic cylinder.
- Avoid dry running to prevent high temperatures from damaging internal components.
- Prevent sand and debris from entering the system to reduce the risk of pump clogging.
Q：The pump is operating but the grease/oil output is low—what should I do?
A:
Please check the following:
- Is the air pressure at the proper level?
- Is the lubricant too thick or hardened?
- Is the grease gun nozzle blocked by debris or foreign objects?
Troubleshooting Tips:
- Check and stabilize the air supply.
- Switch to a softer or lower-viscosity lubricant.
- Clean out any debris from the grease gun nozzle.
Q：The lubricator isn’t dispensing oil (dry running or continuous operation) ?
A:
Please check the following:
- Is the drum empty or low on lubricant?
- Is the lubricant too thick or hardened?
- Is there excessive internal pressure?
- Is the air valve blocked or malfunctioning?
Troubleshooting Tips:
- Refill the lubricant if it’s low or empty.
- Gently release excess internal pressure.
- Allow the pump to run until normal oil flow resumes.
- Clean or service the air valve to restore proper function.
Q：The pump is not operating and air continuously leaks from the exhaust port？
The air valve may be damaged.
Solution: It is recommended to send the pump for servicing and have it repaired by a professional technician.
Q：The lubricator has no air leakage but isn’t dispensing oil ?
Please check：Are there any foreign objects or blockages in the oil line or at the bottom of the suction tube?
