Bell & Gossett Pump 80-SC 3 × 3 × 7B

Verify the driver settings before starting the pump

Ensure the warm-up rate does not exceed 2.5°F (1.4°C) per minute

Flush and clear the system to remove dirt or debris

Bring variable-speed drivers to the rated speed quickly

Run a new or rebuilt pump at a speed that provides enough flow to flush and cool the stuffing-box bushing

Warm up the pump if fluid temperatures exceed 200°F (93°C)

Circulate fluid until casing temperature is within 100°F (38°C) of fluid temperature

Ensure variable-speed drivers are not adjusted during initial startup

Ensure compression tanks and pressure-relief valves are properly sized and located

Verify flange bolts are adequately torqued

Confirm a section of straight pipe or B&G Suction Diffuser is installed between the suction side of the pump and the first elbow

Ensure suction and discharge pipes are independently supported by pipe hangers near the pump

Check for strong, rigid support for suction and discharge lines

Verify bolt holes in pump flanges match bolt holes in pipe flanges

Ensure adequate support for pumps mounted in vertical piping with motor in horizontal position

Confirm suction or discharge lines are not forced into position

Store in a covered and dry location

Store the unit free from heat, dirt, and vibrations

Rotate the shaft by hand several times at least every three months

Treat bearing and machined surfaces so that they are well preserved

Refer to the drive unit and coupling manufacturers for their long-term storage procedures

For questions about possible long-term storage treatment services, please contact your local sales and service representative

Ensure pump is isolated from the system and pressure is relieved

Disconnect and lock out power to the driver

Use proper lifting methods and wear steel-toed shoes

Ensure all replacement parts are available before disassembly

Allow all system and pump components to cool

Close the isolation valves on the suction and discharge sides of the pump

Open the drain valve and ensure liquid stops flowing

Remove the flush line from the seal cap

Tape the collar rings together in pairs as assembled previously

Remove the seal cap or seal gland through the space between shafts
