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.

Frequently Asked Questions
Q: Can this air pump be used to pump gasoline and diesel?
A: 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.
Q: Is this an explosion-proof pump?
A: 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 (such as auto repair shops, oil depots, and mining equipment lubrication sites), thereby eliminating the risk of electric shock or fire.
Q: What is the recommended air input pressure for this pump?
A: The recommended air input pressure ranges from 4 to 8 bar. Operating within this range ensures optimal flow rate control, stable performance, and prevents damage to the internal piston mechanism.
Q: What drum sizes is this pump compatible with?
A: With a suction tube length of 940mm and a standard 2" bung adapter, this pump is specifically designed to fit standard 180L to 209L (55-gallon) drums.
Q: How do I adjust the oil flow rate?
A: You can achieve stepless control of the oil flow rate (ranging from 4 to 18L/min) by installing an air regulator on the air input port and adjusting the incoming air pressure.
Q: Does this pump require regular maintenance?
A: Yes, to ensure long-term durability, it is recommended to use clean, dry, and lubricated compressed air. Installing an air filter-regulator-lubricator (FRL) unit on your air supply line is highly advised.
