Performance and Connection Sizes

The G7-2 Series is engineered for medium-to-high flow applications requiring dependable pressure and continuous-duty operation.

Performance Highlights

• Capacities up to 400 GPM

• Heads up to 145 feet

• Horsepower ranges from 2 HP to 10 HP

• 3" suction connection

• 2" discharge connection

• Maximum liquid temperatures up to 225°F with standard seals

• Inlet pressures up to 100 PSI

• Casing working pressures up to 200 PSI

• Available with single-phase and three-phase motor configurations

• Continuous-duty operation

The oversized 3-inch suction inlet helps promote smooth flow into the pump, while the 2-inch discharge connection delivers the pressure and performance needed for larger commercial and industrial systems.

NPT Threaded Connections

NPT-threaded models provide a cost-effective and compact solution for applications where threaded piping systems are preferred. These pumps are commonly used in OEM equipment, booster packages, water transfer systems, and commercial mechanical rooms.

Benefits of NPT Connections

• Lower installation costs

• Simplified piping modifications

• Compact system footprint

• Easier pump replacement

• Ideal for commercial and packaged equipment applications

• Reduced installation complexity

Flanged Connections

Flanged models are designed for higher-flow applications and larger piping systems where easier alignment and serviceability are important. The bolted flange design provides a secure connection while making maintenance procedures faster and more efficient.

Benefits of Flanged Connections

• Improved piping support and alignment

• Easier pump removal and replacement

• Enhanced reliability in large systems

• Ideal for HVAC, industrial, and municipal applications

• Preferred for high-flow piping networks

• Simplifies long-term maintenance

Maintenance-Friendly Design

The G7-2 Series incorporates Burks' proven back pull-out design, allowing the rotating assembly to be removed without disconnecting system piping. This feature helps reduce downtime, lower maintenance costs, and simplify routine service.

A replaceable casing wear ring further protects the pump casing from wear, helping preserve efficiency and extend equipment life.

Optional High-Temperature Service

For hot water circulation, heat transfer fluids, and thermal oil applications, the G7-2 Series is available with an optional Jacketed Seal Cavity design. This feature helps protect the mechanical seal from excessive heat and extends seal life in elevated-temperature systems.

Typical Applications

• HVAC heating and cooling systems

• Chilled water circulation

• Cooling tower systems

• Industrial process water

• Water transfer and distribution

• Pressure boosting systems

• Manufacturing facilities

• Municipal water systems

• Irrigation systems

• Commercial building services
