Refrigeration oil manual pump

The refrigeration oil manual pump is a specialized tool for filling refrigeration systems. By manually pressing or rotating it, it precisely delivers refrigeration oil to components such as the compressor, ensuring effective lubrication and preventing equipment wear. It's ideal for refrigeration system maintenance.
It's used for replenishing and replacing refrigeration oil in air conditioners, refrigerators, and refrigeration units, meeting maintenance needs.
The pump body and sealing rubber components are manufactured with oil-resistant cast iron, and pressure and sealing tests are performed to ensure durability and leak-proof performance.
This service includes selection and operation guidance. Advantages include accurate filling, easy operation, oil corrosion resistance, and wide compatibility. The refrigeration oil manual pump is a specialized lubrication tool for refrigeration system maintenance. Its core advantages are "precise flow control and oil resistance and durability." It features an oil-resistant, one-piece cast iron forged pump body with fluororubber seals. It is actuated by manually rotating a rocker or pressing a piston. A built-in precision flow control valve prevents compressor lubrication failure due to over- or under-filling. The pump body seal has been pressure-tested to 0.8 MPa, ensuring no leakage and clean, controllable lubrication. It is compatible with compressor oil filling ports on air conditioners, refrigerators, and industrial refrigeration units. Some models feature a check valve to prevent oil backflow and contamination, extending the pump's service life. It can be used for refilling and replacing refrigerant oil in residential air conditioners (wall-mounted and cabinet-mounted), commercial central air conditioners, refrigerators and freezers, cold storage refrigeration units, and heat pumps. Whether it's on-site refilling of old air conditioners by maintenance personnel, initial oil filling of newly installed units at the factory, or regular oil changes during cold storage maintenance, this pump efficiently and accurately performs lubrication operations, providing reliable lubrication for core refrigeration system components, reducing equipment wear and extending operational life.
