Bell & Gossett 617S Series 60 Centrifugal Pump

Run high-head hydronic circulation with Bell & Gossett 617S Series 60 centrifugal pump for multi-story building heating and HVAC service. Its 1-1/2 HP single-phase motor accepts 115 or 208–230 volts, while the 1-1/2-inch by 1-1/2-inch by 7-inch arrangement suits larger loop piping. The supplied data lists a 7-inch bronze impeller, but the official Bell & Gossett curve lists SKU 172724LF/617S with a 6.50-inch impeller.

The 617S uses a Series 60 maintenance-free configuration with a 1-1/2 HP single-phase motor and 175 psi maximum working pressure in the supplied data. Official Bell & Gossett curve information confirms SKU 172724LF and the 1-1/2-inch by 1-1/2-inch by 7-inch pump size, but identifies a 6.50-inch impeller rather than the supplied 7-inch value. Verify the nameplate and trim before ordering.

Key Features & Benefits

• 1-1/2-Inch Pump Size: Helps compare the piping arrangement with existing connections.
• 7-Inch Pump Length: Provides the supplied dimensional reference for replacement planning.
• Bronze Impeller: Identifies the hydraulic material, but diameter requires nameplate confirmation.

Why Choose Bell & Gossett 617S

The 617S provides a larger Series 60 single-phase configuration for high-head hydronics. Its impeller-diameter conflict must be resolved because trim affects the pump curve and operating point.

• Build: The Series 60 arrangement and bronze hydraulic component define the supplied assembly.
• Value: Confirming impeller trim can prevent incorrect capacity assumptions and commissioning problems.
• Audience: Fits boiler technicians, HVAC contractors, facility engineers, and multi-story building maintenance teams.

Applications & Use Cases

Use this pump in high-head hydronic HVAC and multi-story heating systems only after the impeller diameter is confirmed. Check the 1-1/2-inch by 1-1/2-inch by 7-inch arrangement, flange fit, pipe supports, valve clearance, motor access, and system curve.

Warranty & Support

• 3-Year Standard Series 60 Warranty: Bell & Gossett literature states a 36-month warranty from date of manufacture for standard Series 60 pumps.
