Key Features
⚙️
The side of the pump head is equipped with an air regulator input port and an oil outlet port.
🎮
Installing an air regulator on the air input port, adjusting the air intake pressure allows for stepless control of oil flow rate and pressure.
🛡️
The pump stops automatically when the air supply is shut off and automatically releases pressure under no-load conditions, preventing sustained pressure buildup.
🔧
The red bung adapter is used to quickly secure to the threaded opening of the oil drum, making installation and removal convenient.
What’s included in the package
5:1 Oil pump × 1pcs
2” Bung adapter × 1pcs
Frequently Asked Questions
Can this air pump be used to pump gasoline and diesel?
The pneumatic pump is designed for dispensing various types of lubricating oil. It is not suitable for pumping gasoline or diesel; doing so will damage the internal seals and cause the pump to stop working.
Is this an explosion-proof pump?
Purely pneumatic drive—featuring no electric motor and generating no electrical sparks—makes it suitable for flammable and explosive environments where oil or fuel vapors are present, thereby eliminating the risk of electric shock or fire.
What is the recommended air pressure for optimal performance?
The recommended air input pressure is between 4 to 8 bar. Operating within this range ensures the longest lifespan for the internal piston mechanism.
What size of oil drum is this pump compatible with?
This specific model is designed for standard 180-209L (approx. 55 gallon) drums, with a suction tube length of 940mm to reach the bottom effectively.
Does the pump require regular lubrication?
Since it is an air-operated pump, we recommend using an inline air lubricator or adding a few drops of pneumatic tool oil into the air inlet periodically to keep the internal seals supple.
What should I do if the flow rate decreases?
First, check the air input pressure and ensure the air filter is clean. Also, verify that the oil viscosity is within the pump's handled range and that there are no obstructions in the suction tube.
