Xylem Pump 10SV7GH4F66N

Check motor operating hours per day

Verify environment conditions (Dirty, High Moisture)

Determine if lubrication frequency needs adjustment due to elevated temperatures

Ensure not to intermix grease bases (lithium, sodium, etc.)

Purge old grease completely if changing grease base

Avoid over greasing to prevent excessive bearing temperatures and failures

Remove the motor following steps 1 through 4 in the MECHANICAL SEAL REPLACEMENT section

Remove the 4 motor hex cap screws and the motor adapter for motor frames 213TC and larger

Install the motor adapter flange onto the new motor

Torque the 4 hex cap screws to the specified values in the ENGINEERING DATA section

Complete the reassembly following steps 17 through 22 in the MECHANICAL SEAL REPLACEMENT section

Note any additional unit service or maintenance required

Contact local dealer or Goulds Water Technology distributor for assistance if needed

Refer to driver and coupling manufacturers

Store in a covered dry location

Check that all the parts are in place

Is the motor operating within the recommended temperature range?

Ensure no intermixing of grease bases (lithium, sodium, etc.)

Purge old grease completely if changing grease base

Is there moisture present in the environment?

Enter the number of hours the motor operates per day

Is the lubrication frequency increased due to elevated temperatures?

Avoid over greasing to prevent excessive bearing temperatures and failures

Start-Up — Wiring and Grounding

Install, ground, and wire according to local and National Electrical Code requirements.

Install an all leg disconnect switch near pump.

Disconnect and lockout electrical power before installing or servicing pump.

Verify electrical supply matches pump's nameplate specifications.

Ensure wire size limits maximum voltage drop to 10% of motor nameplate voltage.

Verify ground wire is at least as large as wires to the motor.

Ensure wires are color coded for ease of maintenance.

Check three phase motors for all leg protection with properly sized magnetic starters and thermal overloads.
