Application Overview
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, if released would have a significant impact on the environment. As a consequence 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.
Gear pump used to recover liquid refrigerant.
| PUMPING REQUIREMENTS |
MICROPUMP SOLUTIONS |
| FLOW RATE: < 20 lb./min (Freon) |
We have variable speed pumps for this application with flows from 0.2 to 20 lb./min |
| MAX SYSTEM PRESSURE: 450 psi (31 bar) |

| LEAK FREE |
Our magnetic drives eliminates dynamic shaft seals, keeping fluid securely inside the pump and potential contaminants out |
| MAINTAINABILITY |
We offer Service Kits for easy field serviceability |
Micropump Products Optimized for 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 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.
