There may be many causes why the compressor pump is not oiled, and I will explain some possible causes in detail below.
Key Takeaways
- Rotary screw machines dominate continuous-duty industrial use, while piston machines suit intermittent, lower-flow tasks.
- Oil-free technologies safeguard sensitive processes; oil-lubricated designs are economical where air purity is less critical.
- Compare discharge pressure, output flow, motor power, and footprint before selecting a specific model.
Oil pump breakdown:
The oil pump of the compressor may fail, resulting in the inability to absorb and deliver lubricant normally. This may be caused by damage to the internal parts of the pump body, poor seals, or problems with the drive components of the pump.
Oil pump intake blockage:
The air intake of the oil pump of the compressor may be blocked by impurities, dirt or blockages, preventing enough lubricant from being sucked in. This can happen in the air intake filter or in the intake duct, which requires regular cleaning and upkeep.
Oil pump suction pipe leaks:
There may be an air leak in the suction pipe of the oil pump, which prevents the pump from creating enough vacuum pressure to suck in the lubricant. This can be caused by weak pipe connections, aged or damaged seals, etc.
Oil Supply Problems:
There may be problems with the oil supply system of the compressor, such as insufficient oil level in the oil tank, blocked oil pipes or closed oil circuit valves, etc., causing the oil pump to not work properly. Need to check and make sure the oil supply is free.
Oil pump drive problem:
The oil pump driving parts of the compressor may fail, such as motor damage, belt breakage or transmission system breakdown, etc., causing the oil pump to fail to operate normally. This requires appropriate repair or replacement.
Oil pump lubrication problem:
The oil pump itself needs to be lubricated to guarantee normal operation. If the lubricant is insufficient or the quality is not up to standard, it may cause the oil pump to fail to suck and deliver enough lubricant. For this reason, it is necessary to check and replace the lubricant regularly, and guarantee that the appropriate type and specification are used.
Oil pump filter clogged:
The filter of the compressor oil pump may become clogged with impurities, dirt or sediment, causing the oil pump to not work properly. Regular cleaning or changing of filters is key to keeping your oil pump running properly.
In conclusion, the compressor pump not oiling can be caused by oil pump breakdown, oil pump air intake blockage, oil pump suction pipe leakage, oil supply problem, oil pump drive problem, oil pump lubrication problem or oil pump filter clogging, etc. For these problems, careful inspection and upkeep are required to guarantee the normal operation of the compressor and the effective work of the lubrication system. Please note that when dealing with compressor problems, operators should follow the corresponding safety operating procedures and seek professional technical support according to the actual situation.

Frequently Asked Questions
What is the main advantage of a screw compressor?
It delivers continuous, stable air flow with low vibration and is ideal for round-the-clock industrial operation.
When is a reciprocating compressor the better choice?
For intermittent use, high-pressure applications, or lower initial budgets, piston compressors remain a practical option.
What does two-stage compression enhance?
Two-stage compression reduces the compression ratio per stage, improving efficiency and lowering discharge temperature.
