The most versatile general service pump for high pressure water applications

Industrial grade Sunflo pumps are specifically designed for High Pressure applications such as boiler feeds, NOx suppression, reverse osmosis, or high pressure wash down applications that are common to power generation, maritime, transportation or food/beverage industries.   

Single stage Sunflo pumps leverage the engineering knowledge and legacy of the Sundyne heavy duty API pumps to create a family of industrial grade pumps that are ready to take on the toughest applications.  Each member of the Sunflo family is optimized for different flow rates from 10 GPM (1 m³/hr) to 550 GPM (125m³/hr), and head requirements from 100 feet (30m) to 5,280 feet (1,585m). 

  The preferred Choice for Boiler-Feed Applications
Sunflo pumps play an important role in boiler feed applications (like combined cycle, combustion turbine, or Rankine cycle applications).  Industrial grade Sunflo pumps are specifically designed to generate sufficient pressure needed to overcome the steam pressure developed by boilers, making them ideally suited to transfer feed-water into steam drums, and back from condensers, in closed loop cycles.

Boiler feed applications in hospitals, hotels, office complexes, and universities do not require API specifications, but they do require highly efficient, high pressure pumps that can operate reliably. Similarly, boiler feed applications in chemical plants, manufacturing plants, and some refineries are also best-served by non-API, industrial-grade pumps like Sunflo.

Sunflo integrally geared high pressure pumps feature thrust bearings, which absorb axial thrust.  This feature helps Sunflo pumps withstand upset conditions common to co-gen plants with low roof lines and limited space between the deaerator and the pump.  In such scenarios, vapor can travel from the deaerator to the pump, causing upset conditions, or catastrophic pump failure - but Sunflo’s thrust bearings address this condition and enable the pump to reliably operate in this environment.          

The impellers on Sunflo pumps feature a unique Suction Inducer Technology, which is optimized for low NPSH requirements, which helps the pump resist cavitation.  Sunflo pumps also leverage Sundyne’s field proven high pressure impeller technology that is optimized to deliver high head.

Sunflo pumps are also well suited to address harsh chemicals used in boiler feed water applications. Featuring single stage design simplicity and a compact footprint, Sunflo integrally-geared pumps offer 316 stainless steel construction as a standard, with higher alloys available.

Sunflo industrial grade pumps are also well suited for high pressure applications in power, municipal, as well as food and beverage industries.

 

  Maintenance as simple as 1 – 2 – 3 
Sunflo pumps are available in close-coupled, frame-mount, or base plate configurations.  Their versatility, small footprint and ability to be repaired/maintained in place makes them a preferred choice for OEMs and end users around the globe.
