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.
