    LPA® Dual Stage Liquid Refrigerant Pumps

    The model 833-DS is part of their new range of fractional horsepower dual stage liquid refrigerant pumps specifically designed for high-lift applications. Here are some key features and specifications of the Model 833-DS:

    • Low Power Consumption, self-unloading power at maximum flow .5hp (375 Watts)
    • High Pumping Head, 80 feet, 24 meters making it suitable for applications requiring significant liquid line lift for improved heat exchange,
    • Low NPSH pumping head ratio,
    • Ideal for commercial/industrial refrigeration applications,
    • Design provides an additional pressure boost, which is beneficial for high-head refrigeration systems, such as multi-story distribution warehouses.

    The model 833-DS is part of HY-SAVE’s efforts to address liquid line distribution issues in complex refrigeration systems, ensuring efficient and reliable performance.

    833-DS-050-VSD-B

    New to industry model 833-DS, August 2025

    Model 833-DS is third in a series of fractional hp dual-stage ultra-low NPSH LPA® pump series that is available to order in early 2025. It features a flow rate ranging from 2 to 20 GPM and a pumping head of 80 feet for high head refrigeration applications. It adds a second stage pressure boost for higher head pressure applications.

    The 833-DS is self-unloading and does not require regulators or hold back valves substantially reducing cost, developed for high-head refrigeration applications such as multi-story distribution warehouses and other systems facing liquid line distribution issues that reduce refrigeration efficiency.

    The 833-DS is an ideal liquid refrigerant pump for refrigerant heat transfer high head applications including DX free cooling and long liquid refrigerant liquid line applications.

    Certified UL/PED/UKCA

    Model 833-DS is nearing end development and will be available to order in early 2025.
