Every engine needs lubrication to ensure proper operation and extend its service life. The VA-RP940 oil pump is in charge of circulating the oil and keeping the entire engine circuit at the proper pressure and flow rate for proper operation. It can be used in refrigerant systems, for example, in compressors of freezers, minisplit, freezer rooms, etc. It fits all refrigeration oil containers (1, 2 and 5 gallons). In addition, this instrument is a new and universal style of tapered adapter designed to fit all container necks without the need for additional adapters, which saves time and facilitates the task, as it allows you to pump oil into the system while the unit is operating, and can transfer it smoothly to the compressor through the same action.
