Pump and compressor technology
Sundyne centrifugal pumps and compressors are traditionally utilized for processes requiring high-head (pumps: 6,300 ft or 1,921 m)(compressors: 4000 psi or 350 bara), and low-flow (pumps: 1,100 GPM or 250 m3/hr)(compressors: 10000 acfm or 1700 0am3/hr).
Sundyne Sunflo pumps utilize high-speed technology to generate high pressure typically for boiler feed, reverse osmosis, NOx suppression, washdown (food and beverage production), injection, seal flush, and condensate return.
Pump and compressor types and standards manufactured by Sundyne
Sundyne engineered pump and compressor models are compliant with the International Organization for Standardization ISO 13709, and American Petroleum Institute API-610, API-617, API-614, API-685, and ASME/ANSI standards.
