GENERAL TROUBLESHOOTING FOR TONKAFLO PUMPS

5.1

Troubleshooting Chart

5.2

Bearing Frame Temperature

The operating temperature of the oil lubricated E-Bearing frame utilized on high
pressure Tonkaflo pumps will vary depending on the boost pressure of the pump.  As
a general rule, type E-Bearing frames will operate within a temperature range of
130°-203°F (54° - 95°C).  During operation, the bearing frame will feel hot to the touch.

MOTOR RUNS HOT OR STOPS

1. Motor wired improperly
2. Bad connection
3. Motor exceeded rated amp draw
4. Excessive ambient temperature
5. Heater size to small in motor heater
6. Binding rotation in the pump shaft
7. Bearings not adequately lubricated
8. Specific gravity or viscosity of liquid

higher than design conditions

LOW PRESSURE

1. Pump not adequately primed
2. Air leak in inlet piping
3. Excessive flow
4. Clogged suction line filter or screen
5. Reverse rotation of pump shaft
6. Foot valve operating improperly

PUMP LEAKING
