Automatic oil lubrication pumps are essential for keeping your machines running efficiently with minimal wear and tear. But like any mechanical component, they require regular maintenance to ensure optimal performance and a long service life.

At Chiba, we’ve worked with manufacturers across various industries who rely on our lubrication systems to reduce downtime, extend equipment life, and improve operating efficiency. This article is designed to help you understand how to properly maintain your lubrication pump, what common issues to watch for, and how to keep your equipment running smoothly in the long run.

Why Maintenance Matters

Even the best lubrication pump will fail prematurely if not maintained properly. Dirty oil, clogged lines, air bubbles, and sensor failures can all lead to:

• Insufficient lubrication
• Equipment overheating
• Premature wear of machine parts
• Costly downtime

A simple routine check can prevent major repair bills and production losses.

Basic Maintenance Checklist

Here are the key tasks you should regularly perform to keep your automatic lubrication system in good condition:

1. Check the Oil Level

Make sure the oil tank is always filled with the correct lubricant type and viscosity as recommended by the equipment or pump manufacturer.

Tip: Low oil levels can trigger alarms or stop lubrication altogether. Check the oil level weekly or before each shift in high-demand environments.

2. Inspect for Leaks

Examine all tubing, fittings, and connections for signs of leakage. Even small leaks can lead to pressure drops and uneven oil delivery.

Tip: Look for oil stains under the pump or on the machine body. Tighten fittings or replace worn-out tubing when necessary.

3. Clean the Filter

Most systems include an oil filter to trap impurities. A clogged filter can reduce oil flow or damage the pump.

Tip: Clean or replace the filter every 3–6 months, depending on the environment and oil quality.

4. Monitor the Distribution Lines

Ensure that each lubrication point is receiving oil. Blocked or kinked lines can result in dry spots that accelerate wear.

Tip: Mark each lubrication point and visually confirm oil delivery during system operation.

5. Test Electrical Connections and Timers

For electrically controlled pumps, verify that the timer or controller is working as expected.

Tip: Look for error codes on the control panel and test the system cycle periodically.

Common Issues and Troubleshooting

Here are a few issues customers often encounter with auto oil lubrication pumps—and how to fix them:

Issue	Possible Cause	Recommended Action
Pump not dispensing oil	Empty tank / Air in line / Electrical failure	Refill oil, bleed air, check power supply
Uneven lubrication	Blocked lines or nozzles	Clean or replace the affected parts
Excessive oil flow	Faulty metering units or wrong settings	Adjust timer/controller, inspect flow regulators
Noisy pump	Worn-out internal parts or dry run	Lubricate or replace the pump components
Oil contamination	Dirty oil or damaged filter	Drain and replace oil, clean tank and filter

Tips for Long-Term Reliability

• Use Clean Oil Only: Always use high-quality, compatible oil. Contaminated oil is the number one cause of internal damage.
• Label and Document: Keep a maintenance log to track oil changes, filter cleaning, and repairs.
• Train Your Staff: Make sure operators understand basic troubleshooting and visual checks.
• Schedule Preventive Maintenance: Don’t wait for failures—set a monthly or quarterly inspection routine.

Frequently Asked Questions (FAQ)

Q1: How often should I check or refill the oil in my auto lubrication pump?

A: It depends on your machine usage and operating environment. For most industrial applications, we recommend checking the oil level at least once a week. In high-speed or 24/7 operations, daily checks are advisable.

Q2: Can I use any type of oil with Chiba lubrication pumps?

A: No. Always use the lubricant type and viscosity recommended by Chiba or your equipment manufacturer. Using the wrong oil can cause clogging, over-lubrication, or premature pump failure.

Q3: What should I do if the lubrication points are not receiving oil?

A: First, check for air bubbles, clogged lines, or insufficient oil in the tank. Also inspect the controller and timers. If all else fails, contact Chiba’s technical support for step-by-step diagnostics.
