Flanged Connections

Flanged models are designed for larger piping systems and applications requiring enhanced support, easier alignment, and simplified pump removal. The bolted flange configuration provides a secure connection and is commonly specified for HVAC, cooling tower, manufacturing, and process water systems.

Advantages of Flanged Connections:

• Increased system reliability for larger pipe sizes

• Easier pump removal during maintenance

• Improved piping alignment

• Better suited for high-flow applications

• Reduced stress on pump connections

• Preferred for industrial and institutional installations

Maintenance-Friendly Design

The G6-2 Series incorporates Burks' proven back pull-out design, allowing the rotating assembly to be removed without disconnecting system piping. This feature helps minimize downtime, reduce labor costs, and simplify routine maintenance procedures.

A replaceable casing wear ring further protects critical pump components while helping maintain long-term hydraulic efficiency.

Optional High-Temperature Service

For applications involving hot water, thermal oils, and heat transfer fluids, the G6-2 Series can be furnished with an optional Jacketed Seal Cavity design. This specialized configuration helps extend seal life and improve reliability in elevated-temperature systems.

Typical Applications

• HVAC heating and cooling systems

• Chilled water circulation

• Cooling tower operation

• Industrial process water systems

• Water transfer and distribution

• Pressure booster systems

• Manufacturing facilities

• Commercial building services

• Municipal water applications

• OEM equipment packages
