Move primary HVAC water with Bell & Gossett 622T Series 60 centrifugal pump for three-phase high-volume hydronic circulation. Its 3/4 HP motor accepts 208–230 or 460 volts, while the 3-inch by 3-inch by 5-1/4-inch pump size supports larger commercial piping layouts. A 5-1/4-inch bronze impeller and three-piece in-line design provide defined replacement details. Confirm flange alignment, phase rotation, system resistance, and service clearance before installation.

The 622T uses a three-piece in-line centrifugal arrangement with a 5-1/4-inch bronze impeller and 3-inch connections. Its three-phase motor operates at 208–230 or 460 volts, so technicians must verify both supply voltage and phase rotation before startup. The supplied Series 60 design is identified as maintenance-free for service planning. Flow, head, RPM, seal construction, dimensions, weight, and working pressure are not stated, so verify the manufacturer’s current documentation.

Applications & Use Cases

Use this pump for three-phase high-volume hydronics and primary HVAC circulation where the existing piping and system curve are compatible. Check the 3-inch connection dimensions, gasket fit, pipe supports, valve clearance, motor access, and lifting path before installation. The supplied data does not include overall dimensions, weight, flow, head, or pressure, so verify those details from the manufacturer’s submittal.

Warranty & Support

- Warranty Terms: Warranty duration, coverage, exclusions, and registration requirements require confirmation from the authorized seller.
- Service Requirements: Confirm whether authorized service is required for warranty claims before purchase.
- Model Verification: Match Bell & Gossett 622T and SKU 172759LF to the seller’s order documentation.

Verify voltage and phase rotation, align the 3-inch connections, purge air from the loop, inspect strainers, and confirm pipe supports before commissioning. Select the pump from the actual system curve because flow and head are not supplied here.
