820-DS-050-VSD-B
low lift liquid refrigerant pump
The 820-DS-050-VSD-B (Dual Stage) LPA® (Liquid Pressure Amplifier) is a specialized pump used in various refrigeration applications to enhance system efficiency and performance. Its design focuses on continuous operation with minimal power consumption and low Net Positive Suction Head (NPSH) requirements, which is essential for maintaining the reliability and effectiveness of refrigeration systems.
Applications include:
- Centrifugal Compressor Cooling: Improving the efficiency of centrifugal compressors by providing stable liquid refrigerant supply at low or part load compression ratios.
- Suppressing Liquid Line Flashing: Preventing the formation of flash gas in the liquid line, which can reduce system efficiency.
- Super-heat suppression: Maintaining optimal superheat levels to ensure efficient refrigeration cycles, scale elimination, reduced drift loss, evaporative and water cooled condensers.
- Compressor discharge cooling: Reducing compressor discharge temperatures to extend the lifespan of the equipment. Extraction of compression heat to outdoors utilizing the systems working fluid heat exchange.
- DX-re circulation: Enhancing the direct expansion refrigeration cycle through improved refrigerant circulation having indirect vapor compression.
- Floating Head Pressure: Allowing the condensing pressure to adjust with ambient temperatures, leading to energy savings.
