VP245 Vacuum Pump
Product Information
The Vacuum Pump Model VP245 is a high-performance pump designed
to create a vacuum in various systems. The pump components include
a handle, sight glass, die-cast aluminum housing, oil drain, fan
cover, motor, and base. The package includes a 5 CFM vacuum pump, a
330ml oil bottle, a 230ml oil bottle, and a user manual. When
operating the pump, it is important to maintain the oil level even
with the line on the sight glass to ensure optimal performance.
Overfilling can result in oil blowing from the exhaust.
Product Usage Instructions
Safety Instructions: Before operating the
vacuum pump, read the instruction manual carefully and save it for
future reference. Basic safety precautions should always be
followed. Ignoring safety warnings may lead to accidents. The
device complies with Part 15 of the FCC Rules. Operation is subject

particles from entering the port.
Maintenance Instructions: To maintain your high
vacuum pump, follow these steps:
- Check the oil level before each use and add oil if
necessary. - Change the oil after every 50 hours of use or when the oil
appears dirty. - Clean the pump regularly to prevent dust and debris
buildup.
Troubleshooting Guide: If the pump
malfunctions, follow the troubleshooting guide provided in the user
manual. If disassembly is required, check your warranty as it may
be voided by misuse or customer tampering.
Common Troubleshooting:
| Failure Description | Fault Cause | Solution |
|---|---|---|
| Low Vacuum | The air inlet cap on the spare port side of the air inlet port is loose or damaged, or there is insufficient oil. | Tighten the air inlet cap, replace the damaged rubber ring, or add oil to reach the optimal level. |
| Oil Leakage | The pump oil is emulsified and unclean, or there is leakage in the pipe container connected to the pump. | Change the pump oil and clean it before use. Check for any leakage in the pipe container and repair it if necessary. |
| Oil Injection | The oil inlet hole of the pump is blocked or the oil supply is insufficient. | Clean the oil inlet hole and ensure a sufficient oil supply. |
| Hard Starting | Improper pump selection or the pump has been used too long, and the clearance is increased due to the wear of parts. | Select the appropriate pump for the system and replace any worn parts if necessary. |

OPERATING MANUAL
1.Before using your vacuum pump In all cases, motors are designed for operating voltages plus or minus 10% of the normal rating. Single voltage motors are supplied fully connected and ready to operate. (1)Check to be sure the voltage and frequency at the outlet match the specifications on the pump motor decal. Check the ON-OFF switch to be sure it is in the OFF position before you plug the pump into an outlet.Remove and discard the exhaust cap from the end of the pump’s handle. (2)The pump is shipped without oil in the reservoir.Before starting the pump, fill it with oil.Remove the Exhaust Fitting cap and add oil until the oil just shows in the bottom of the sight glass. The approximate oil capacity of the pump is 180~800ml(reference the technical data). (3)Replace the Exhaust Fitting cap and remove the cap from one of the inlet ports. Turn the motor switch to ON.When the pump runs smoothly, replace the cap on the inlet port. This may take from two to 30 seconds, depending on the ambient temperature.After the pump runs for approximately one minute, check the sight glass for the proper oil level. The level should be even with the sight glass oil level line. Add oil if necessary.
Note:When the pump is running, the oil level should be even with the line on the sight glass. Underfilling will result in poor vacuum performance.Overfilling can result in oil blowing from the exhaust.

2.To shut down your pump after use To help prolong pump life and promote easy starting. Follow these procedures for shut down. (1)Close the manifold valve between the pump and the system. (2)Remove the hose from the pump inlet. (3)Cap the inlet port to prevent any contamination or loose particles from entering the port.
TO MAINTAIN YOUR HIGH VACUUM PUMP
1.Vacuum pump oil: The condition and type of oil used in any high vacuum pump are extremely important in determining the ultimate attainable vacuum. We recommend the use of High Vacuum Pump Oil.This oil has been specifically blended to maintain maximum viscosity at normal running temperatures and to improve cold weather starts. 2.Oil Change Procedure (1)Be sure the pump is warmed up. (2)Remove the OIL DRAIN cap. Drain contaminated oil into a suitable container and dispose of it properly. Oil can be forced from the pump by opening the inlet and partially blocking the exhaust with a cloth while the pump is running. Do not operate the pump for more than 20 seconds using this method. (3)When the flow of oil has stopped, tilt the pump forward to drain residual oil. (4)Replace the OIL DRAIN cap.Remove the exhaust fitting and fill the reservoir with new vacuum pump oil until the oil just shows at the bottom of the sight glass. The approximate oil capacity of the pump is 180-800ml(reference the technical data). (5)Be sure the inlet ports are capped, then turn on the pump. Allow it to run for one minute, then check the oil level space. If the oil is below the sight glass OIL LEVEL line, add oil slowly (with the pump running )until the oil reaches the OIL LEVEL line. Replace the exhaust fitting, making sure the inlet is (6) a)If the oil is badly contaminated with sludge that forms when water is allowed to collect in the oil,you may need to remove the oil reservoir cover and wipe it out. b)Another method of dealing with heavily contaminated oil is to force the oil from the pump reservoir. To do this, allow the pump to run until it is warmed up. While the pump is still running, remove the oil drain cap. Slightly restrict the exhaust. This will backpressure the oil reservoir and force the oil from it, carrying more contamination. When the oil ceases to flow, turn off the pump. Repeat this procedure as required until the contamination is removed. Replace the OIL DRAIN cap and refill the reservoir to the proper level with fresh pump oil.

TROUBLESHOOTING GUIDE
Your pump has been for dependable use and has a long life. If something should go wrong, the following guide will help you get the pump back into service as quickly as possible.
If the disassembly of the pump is required, please check your warranty.The warranty may be voided by misuse or customer tampering, which results in the pump being inoperable.
1.Failure To Start Check the line voltage. The pump needs to start at±10% line voltage (loaded) at 320F.At extremes,switching between the standard run windings may occur. 2.Oil leakage (1)Be sure the oil is not a residual accumulation from spillage, etc. (2)If leakage exists, the module cover gasket or the shaft seal may need replacing. If leakage exists in the area of the oil drain plug, you may need to reseal the plug using a commercial pipe thread sealer. 3.Failure To Pull A Good Vacuum (1)Be sure the vacuum gauge and all connections are in good condition and leakfree.You can confirm leakage by monitoring the vacuum with a thermistor gauge while applying vacuum pump oil at connections or suspected leak points. The vacuum will improve briefly while the oil is sealing the leak. (2)Be sure the pump oil is clean. A badly contaminated pump may require several oil flushes. (3)Be sure the oil is at the proper level.For maximum pump operation, the oil must be even with the OIL LEVEL line on the sight glass when the pump is running. Do not overfill—- operating temperatures will cause the oil to expand, so it will appear at a higher level than when the pump is not running. To check the oil level, start the pump with the inlet capped. Check the oil level in the sight glass. Add oil if necessary.

Check the connected pipe container to prevent leakage Check the size of the pumped container, recalculate and select the appropriate pump model Check, repair, or replace the pump with a new one
1. The oil seal is damaged
Replace the oil seal
2. The oil tank connection is loose or damaged
1.Too much oil
Tighten the screws and replace the O-ring
Drain the oil to the oil level line
2.The inlet pressure is too high for a long time
Select the appropriate pump to increase the pumping speed
1. The oil temperature is too low
The air inlet is ventilated, repeatedly starts the motor or heats the pump oil
2. The motor or power supply is faulty
3. Foreign objects fall into the pump
Check and repair Check and eliminate
4. The power supply voltage is too low
Check the power supply voltage
Note: If the above solutions do not solve your problem, please contact the nearest dealer, or send your pump to a professional repair center, and we will do our best to serve you.
