BACOENG Vacuum Pumps

BACOENG provides a range of vacuum pumps designed for various applications, including automotive air conditioning, degassing, and industrial uses.

Vacuum and Ultimate Vacuum

Atmospheric pressure at sea level is approximately 100,000 Pa (760 mmHg). When air or gas is removed from a closed container, a vacuum is created.

Vacuum gauges measure relative pressure.
Ultimate vacuum is the lowest pressure a pump can theoretically reach.
Leaks, moisture, and oil condition affect achievable vacuum.

So, What Is the Right Type of Vacuum Pump?

There are many types of vacuum pumps. Rotary vane vacuum pumps are among the most common due to their balance of cost and performance.

Single-stage pumps: typically reach ~1 Pa (7.5 microns)
Double-stage pumps: achieve deeper vacuum levels

BACOENG Vacuum Pump Compared with Other Brands

BACOENG vacuum pumps are designed to provide good performance at a competitive price.

Built-in oil mist filter
Integrated vacuum gauge
Available in 110V and 220V versions
Double-stage models can reach 0.01 Pa (0.075 microns)

Different Applications, Different Pumps

Different applications require different pump sizes and vacuum levels.

Common Models

BA-1A Mini Pump: Portable, suitable for small AC systems
BA-1 Standard Pump: General-purpose, 1/4 HP motor
2BA-1.5: Double-stage, 5 CFM
2BA-4: Heavy-duty, 16 CFM
Oil-Free Pumps: Used where oil contamination must be avoided

Typical Applications

Vacuum pumps are commonly used for:

AC system evacuation
Degassing resin, epoxy, or silicone
Wine degassing
Vacuum forming
Vacuum packaging
Laboratory and research use

Common Problems and Solutions (FAQs)

Is it necessary to refill oil?

Yes. Vacuum oil lubricates internal parts and ensures proper sealing.

Can other oil be used instead of vacuum oil?

No. Only vacuum pump oil has sufficiently low vapor pressure.

Why does my pump get hot and stop?

Possible causes include:

Incorrect oil
Running without load for extended periods
Pump size mismatch

Do leaks or liquids affect vacuum?

Yes. Leaks introduce air, and liquids can vaporize under vacuum, reducing performance.

Is oil mist from the exhaust normal?

Some oil mist is normal. Excessive mist may indicate oil or usage issues.

Why can’t I reach full vacuum (e.g. 27" Hg instead of 30")?

Altitude, leaks, and gauge accuracy all affect readings.

Why does oil flow back into the chamber?

Always close the valve before shutting off the pump, and start the pump before opening the valve.

What Should I Do When Failure Occurs?

Most issues can be diagnosed by checking oil level, seals, and connections. If problems persist, contact technical support.
