Xylem Pump 15SV4GA1A10

WARNING — DISCONNECT AND LOCKOUT ELECTRICAL POWER BEFORE ATTEMPTING ANY MAINTENANCE. FAILURE TO DO SO CAN CAUSE SHOCK, BURNS OR DEATH.

Mechanical Seal Replacement (e-SV 1–125) — Conventional Seal

Close all necessary suction and discharge valves to isolate the pump from the system.

Drain the liquid from the pump by removing the drain plug and opening the needle valve on the vent plug.

Remove the coupling guards, the 4 coupling hex cap screws, the coupling and coupling drive pin.

Remove the 4 motor hex cap screws (inner screws) on the seal housing.

Remove the seal housing plate on 33-125SV models using the two tapped holes provided.

Turn the seal housing upside down and remove the stationary seat and o-ring.

Check motor operating conditions

Is the motor operating at elevated temperatures?

Increase lubrication frequency if operating at elevated temperatures

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

Completely purge old grease if changing grease base

Ensure not to over grease to avoid excessive bearing temperatures and failures

Recommended Motor Bearing Lubrication Intervals

Are lubricants operated at elevated temperatures?

Is the lubrication frequency increased for elevated temperatures?

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

Completely purge old grease if changing grease base

Check for signs of over greasing

Describe any issues found during lubrication

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

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.

Does the electrical supply match the pump's nameplate specifications?

Use only stranded copper wire to motor and ground.

Enter the wire size to ensure it limits the maximum voltage drop to 10% of the motor nameplate voltage.

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

Check that wires are color coded for ease of maintenance.
