4.2Mechanical Seal Leakage

WARNING: POWER MUST BE DISCONNECTED BEFORE MAINTENANCE!

If liquid is leaking from the hole on the bottom or on either side of the motor adapter, the mechanical seal may need to be replaced. With new pumps, pumps with new mechanical seals, or pumps which have been dormant for long periods, the seal faces may not be completely seated and a slight leakage will occur. If this leakage contin- ues for more than 60 seconds, the first remedy is to remove the discharge piping and tap the pump shaft using a wooden dowel to seat the seal.

WARNING: BE CAREFUL NOT TO DAMAGE THE SHAFT.

If this does not stop the leak, then the liquid end assembly needs to be partially removed to gain access to the mechanical seal as shown in Figure 4.5 (Removal of Pump Liquid-End from Motor Adapter) or Figure 4.6 (Removal of Mechanical Seal from Motor Adapter).

The ceramic seal seat also needs to be wiped clean and then coated very lightly with oil or Vaseline. Also, the carbon wear ring needs to be wiped clean and coated light- ly with petroleum grease. Then, reassemble the pump.

4.3Mechanical Seal Replacement: SS500, SS1000 and SS1800 Series Pumps

NOTE: On Tonkaflo X frame pumps, the mechanical seal must be replaced by removal of the complete liquid end assembly from the pump shaft. On Tonkaflo XB and XC frame pumps, you can service the mechanical seal by either removing the complete liquid end assembly from the pump shaft, or by loosening the cone-point set screw which secures the pump shaft to the shaft coupler, and removing the pump shaft with the liquid end assembly.

STEPS

1.Remove the four (4) 5/16-inch bolts and lock washers from the inlet casting and firmly grasp the liquid end (Figure 4.5, Removal of Pump Liquid-End from Motor Adapter). Pull the liquid end straight off the pump shaft being careful not to bend the pump shaft. Two (2) flat-blade screwdrivers may be needed to remove the seal holder from the liquid end assembly.

WARNING: EXTREME CARE MUST BE TAKEN NOT TO BEND PUMP SHAFT!

2.Remove the stainless steel retaining ring (size 5160-62H) from the pump shaft using the proper size retaining ring pliers (Truarc L1520 or equivalent). These pliers are available from the factory or can be purchased from a local source.
