Xylem Pump 3SV4CA1A10

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.

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

Verify environment conditions (Dirty, High Moisture)

Determine if lubrication frequency needs adjustment due to elevated temperatures

Ensure not to intermix grease bases

Purge old grease completely if changing grease base

Avoid over greasing to prevent excessive bearing temperatures

Ensure pump is inactive in freezing conditions

Has suitable antifreeze been added to the water?

Drain pump through the drain plugs if no antifreeze is present

Ensure drained liquid does not cause damage or injuries

Check motor operating conditions

Is the motor operating at elevated temperatures?

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

Completely purge old grease if changing grease base

Avoid over greasing to prevent excessive bearing temperatures and failures
