Micropump applications refrigerant recovery
A refrigerant is a substance or mixture, usually, a fluid, used in a heat pump or refrigeration cycle in a variety of automotive, commercial and residential applications. Many fluids have been used as refrigerants, and most of them would have a significant impact on the environment if released. Consequently, the recovery of these fluids during system recharging and at the end of product life is essential. Recovery is the process of removing refrigerant from a system and storing it for future recycling or reclaiming.
Gear pumps provide a simple solution for removing liquid refrigerant from the “high side” of the system and transferring it to a storage tank.
PUMPING REQUIREMENTS | MICROPUMP SOLUTIONS |
FLOW RATE: < 20 lb./min (Freon) |
variable speed pumps for this application with flows from 0.2 to 20 lb./min |
MAX SYSTEM PRESSURE: 450 psi (31 bar) |
Pumps operate up to 1500 psi (103 bar) max system pressure |
MAX DIFFERENTIAL PRESSURE: 40 psi (2.76 bar) |
Pumps operate up to 125 psi (8.6 bar) max differential pressure |
CHEMICAL COMPATIBILITY: With refrigerant and acids formed from moisture and impurities |
Chemically resistant construction materials stand up to the aggressive fluids found in refrigerants (PEEK, PSS, TEV, 316SS) |
LEAK-FREE |
Magnetic drives eliminate dynamic shaft seals, keeping the oil and gas securely inside the pump and potential contaminants out |
MAINTAINABILITY |
Micropump offers Service Kits for easy field serviceability |
MICROPUMPS PUMPS COMMONLY USED IN THIS APPLICATION
Micropump GD Series and GC Series are most commonly used in this application. These gear pumps offer smooth pulseless flow avoiding vaporization caused by large pulsations from the diaphragm, piston, or centrifugal pumps. The wetted materials of these pumps are well suited for use with common refrigerants. When installing these pumps, maximize the diameter and minimize the length of input lines to avoid vapor formation. Ideally the pump should be placed below the liquid source.
