Specifically designed for hot water and glycol-based systems, the RWA4166 stands out due to its reliability, durability, and thoughtful engineering that minimizes operational complexity while enhancing efficiency.
A Tradition of Excellence in High-Temperature Pumps
With over a century of experience in designing and manufacturing pumps for high-temperature service, Dean Pumps has consistently delivered solutions that meet demanding industrial requirements. The RWA4166 continues this tradition, offering best-in-class quality and cost-effective performance for hot water and water/glycol systems. This pump series exemplifies engineering expertise and innovation, making it an ideal choice for boiler feed, steam condensate return, HVAC, and heat transfer applications.
Performance-Driven Design Features
High-Temperature Capabilities:
The RWA4166 is specifically designed to handle temperatures up to 400°F, making it a perfect solution for heat transfer systems involving hot water, ethylene glycol, propylene glycol, and triethylene glycol. This capability ensures reliable performance in applications where temperature control is critical.
Air-Cooled Efficiency:
Unlike traditional pumps that require external water cooling, the RWA4166 utilizes a shaft-mounted fan to cool the bearings and mechanical seal. This air-cooled design eliminates the need for water cooling systems, significantly reducing operational costs and simplifying maintenance.
Centerline-Supported and Yoke-Mounted Design:
The RWA4166 features a centerline-mounted casing, minimizing thermal growth around the pump’s centerline. This design maintains alignment during temperature fluctuations, ensuring consistent and reliable operation. The yoke-mount casing support further enhances stability, effectively resisting thermal expansion and piping loads.
Class 300 Raised Face Flanges:
Equipped with Class 300 raised face flanges, the RWA4166 ensures superior sealing capabilities and pressure containment. This robust construction enhances operational safety and reliability, making it ideal for demanding environments.
Angular Contact Thrust Bearings:
To handle axial loads efficiently, the RWA4166 incorporates a pair of angular contact thrust bearings. This arrangement extends bearing life and promotes system stability, reducing downtime and maintenance costs.
Compatibility and Easy Integration
The RWA4166 is dimensionally interchangeable with the R4140 series, allowing for straightforward upgrades and replacements. This compatibility minimizes the need for extensive piping or structural modifications, reducing installation time and costs. Additionally, the pump can be mounted on ASME/ANSI B73.1 design baseplates, ensuring seamless integration into existing systems.
Applications Suited for the Dean RWA4166
The RWA4166 is optimized for a variety of high-temperature applications, including but not limited to:
- Boiler Feed Systems: Reliable pumping of hot water for steam generation.
- Steam Condensate Return: Efficient handling of condensate return in steam systems.
- HVAC Systems: Hot water circulation for heating and cooling applications.
- Heat Transfer Systems: Effective heat transfer fluid circulation in industrial processes.
Additional Features for Operational Efficiency
Back Pull-Out Design:
Maintenance and repairs are simplified with the back pull-out design, allowing the entire rotating assembly to be removed without disturbing the piping or motor. This reduces downtime and simplifies service procedures.
Mechanical Seal Protection:
The single inside, balanced mechanical seal is isolated from hot water, providing cool operation and extending seal life. This design feature ensures that the pump continues to operate efficiently even in demanding conditions.
Rugged Construction for High Durability:
The heavy-duty casing and self-venting, top-centerline discharge design enhance operational safety and reduce wear, making the RWA4166 a dependable choice for long-term performance.
No External Cooling Required: Cost-Saving Innovation
By eliminating the need for external water cooling systems, the RWA4166 reduces operational costs and simplifies the system design. This innovation translates to significant savings over the pump’s operational life while maintaining excellent performance in high-temperature environments.
