Sundyne centrifugal pump

Sundyne & Sunflo
High Speed Pumps & Compressors

Sundyne Heavy Duty Pumps to ISO-13709, API-610 (OH5,OH6), and Sunflo Pumps are the perfect choice for High-Head, Low-Flow applications.

Pumps are capable of flow rates up to 360 m³/h and heights of up to 4,500 m. Compressors even handle flow rates up to 17,000 m³/h and have a maximum working pressure up to 350 bar.


Technology: High-speed centrifugal pumps & compressors

Since their inception, the Sundyne process pumps and multi-stage pumps in accordance with ISO 13709 and API 610 (OH5, OH6) have been the definitive word in high-head, low-flow applications.

The Sunflo high-pressure pump product line harnesses our high-head, low-flow technology and experience for use in general industry applications. Sunflo pumps are used globally, by both OEMs and end users in equal measure. Typical applications include boiler feed, reverse osmosis, NOx suppression, washdown, injection, seal flush, and condensate return applications.

Over the years, Sundyne compressors have evolved from the reliable, integrally geared line-mounted compressor (LMC) technologies that are according to API-617 standard to the base-mounted (BMC) and Pinnacle multi-stage units.
