Jlab Export is a leading Combination Oil Pump Manufacturer,and suppliers in India
This hand pump charges oil into a compressor while the system stays under pressure, so the refrigerant does not have to be recovered first. It pumps on the down stroke, delivers 2.6 oz (78 ml) per stroke and works against 200 psi or more. With the suction transfer hose supplied, it also draws oil out of equipment for recovery or conversion.

Oil Charging Practicals
On a training unit such as the Refrigeration Test Rig, students can top up compressor oil without recovering the charge. They fit the stopper into the oil container, pump until oil reaches the hose end to push the air out, and connect to the compressor oil charging port. Counting the strokes gives the volume added, at 78 ml for each one.
For an oil change or a refrigerant conversion, the suction hose lets the pump draw the old oil out of the equipment. Trainees check that oil with the Acid Test Kit For All Refrigeration Oils, then refill with fresh POE Oil or Mineral Oil, as the compressor and refrigerant require.
Frequently Asked Questions
Can it add oil while the system is charged?
Yes. It is built to pump against 200 psi or more, so the refrigerant can stay in the system. Connect to the low-pressure side of the compressor, where pressure is lowest, and purge the air from the hose first.
How do I know how much oil has gone in?
Count the strokes. Each full stroke delivers 2.6 oz (78 ml), so multiply the count by that amount and stop at the quantity the compressor needs.
Which oils can it pump?
Alkyl-benzene, ester-based, polyester, mineral and synthetic oils. Pump some of the new oil through the pump and hose when you change type, so the old oil is not carried into the next system.
Will it fit my oil containers?
The universal stopper adjusts to the standard openings of 1, 2-1/2 and 5 gallon oil containers. Oil is drawn straight from the closed container, so it spends little time open to moist air.
