Viking 4924A - Ammonia Pump

The 4924A internal gear pump is used for ammonia circulation in refrigeration systems, maintaining the refrigerant in liquid form for efficient heat transfer. It is suited for industrial cooling and process refrigeration applications. It delivers flows from 10 to 60 GPM (2.3 to 13.6 m³/h) with pressures up to 50 PSI (3.5 bar). The pump operates within temperature ranges from -40 to +225 °F, supporting stable ammonia handling conditions. Constructed in cast iron, the pump provides durability for refrigeration environments. It is specifically configured to handle ammonia while maintaining process efficiency and operational stability. A double mechanical seal with barrier fluid ensures reliable containment and minimizes leakage risk. Multiple porting and drive configurations allow integration into refrigeration and cooling systems.
