For professionals in the HVACR industry, precision and reliability are non-negotiable. The process of adding oil to refrigeration and air conditioning compressors is critical for system longevity and efficiency. A specialized Refrigeration Oil Charging Pump is the definitive tool for this task. Unlike makeshift methods, these pumps are engineered to transfer oil accurately, cleanly, and safely, preventing system contamination and ensuring the correct oil charge is delivered directly into the compressor crankcase. This is essential for maintaining compressor lubrication, reducing wear, and ensuring the entire system operates at peak performance. At Raydafon Group, we understand these demands and engineer our pumps to meet the rigorous standards of the field.
Manual oil charging is fraught with potential issues—inaccurate measurements, air and moisture ingress, and spillage. The Raydafon Group oil charging pump eliminates these problems. Our pumps offer:
Investing in a Raydafon pump is investing in the reliability of your service work and the health of the systems you maintain.

Raydafon's oil charging pumps are versatile tools designed for a wide spectrum of refrigeration and air conditioning applications. They are indispensable for:
Q: How do I know which type of refrigeration oil to use with the pump?
A: The pump itself is compatible with all common oils. The oil type (POE, PAG, Mineral, AB) must always be specified by the compressor or system manufacturer. Using the wrong oil can cause severe damage. Always consult the system's documentation or nameplate. Raydafon Group pumps are designed to handle the full viscosity range of these oils without issue.
Q: Can I use the same pump for different types of oil?
A: While technically possible, it is strongly discouraged to avoid cross-contamination. Even small amounts of mixed oils can lead to chemical incompatibility, acid formation, and system failure. Best practice is to dedicate one pump to a specific oil type or to perform a thorough flushing procedure with a compatible solvent (and subsequent drying) when switching oils. For high-purity applications, Raydafon Group recommends using separate pumps.
Q: My pump is not delivering oil or is pumping very slowly. What should I check?
A: First, ensure the reservoir has sufficient oil. Then, check for the following common issues:
1. Air Lock: Prime the pump according to the manual, often by opening the discharge valve and operating the pump until a steady stream of oil appears.
2. Clogged Inlet Filter: Inspect and clean the filter screen inside the reservoir.
3. Viscosity & Temperature: Very high viscosity oil in cold conditions will flow slower. Warm the oil reservoir to the manufacturer's recommended handling temperature if necessary.
4. Worn Pump Seals/Valves: With extended use, internal seals may wear. Consult the Raydafon service manual for inspection procedures.
Q: How do I calibrate or verify the accuracy of the oil charging pump's meter?
A: Raydafon pumps are factory-calibrated. To verify accuracy, perform a simple field check: Pump a known volume (e.g., 100 ml) into a clean, graduated cylinder. Compare the delivered volume to the pump's meter reading. If a significant discrepancy is found, consult the user manual for calibration adjustment instructions or contact Raydafon Group technical support. Regular verification is recommended for critical applications.
Q: Is it necessary to evacuate the pump or hoses of air before charging oil into a system?
A: Yes, absolutely. Introducing air into a refrigeration system introduces non-condensable gases and moisture, which degrade performance and can cause damage. Always purge the pump's discharge hose by running a small amount of oil through it into a waste container until all air bubbles are eliminated before connecting to the system's service port.
Q: What maintenance does a Raydafon oil charging pump require?
A: Routine maintenance ensures longevity and accuracy:
- After Each Use: Wipe down the exterior. If switching oil types, flush thoroughly.
- Regularly: Inspect hoses for cracks or wear. Check fittings for tightness and leaks.
- Periodically: Inspect and clean the inlet filter. Check the sight glass for clarity.
- Annually or per Usage: Replace wear items like pump seals or valve O-rings as per the maintenance kit instructions from Raydafon Group. Verify metering accuracy.
Q: Can this pump be used to remove oil from a compressor as well?
A: The primary design is for charging. However, many models, including those from Raydafon Group, can be used for controlled oil removal by connecting the discharge hose to a recovery container and using the pump in reverse (if designed for bidirectional flow) or by siphoning, provided the pump's mechanism allows it. Always consult your specific model's manual. For large-scale or rapid oil removal, a dedicated oil recovery pump is more efficient.
Q: Why should I choose Raydafon Group over other brands?
