Possible Solution
Little or no cutting fluid is being pumped. Pump and motor may also vibrate or be noisy.
1.No power; voltage is incorrect.
2.Blown fuse/tripped circuit breaker at main panel.
3.Coolant level is too low, and pump cavitation is occurring.
4.Coolant is incorrect, or is too thick and incorrectly mixed.
5.Pump is operating in reverse.
6.Motor or cover is loose.
7.Debris is obstructing pump suction or impeller is damaged.
8.Plug or receptacle is corroded or
9.Break or short in wiring; or loose connections.
10.Pump ON/OFF switch at fault.
11.Motor connection wired incorrectly.
12.Emergency stop button is at fault.
13.Thermal relay has tripped.
14.Transformer is at fault.
15.Contactor not energized/has poor contacts.
16.Motor at fault.
1.Switch power supply ON/verify machine and pump voltages match.
2.Correct the cause of overload, then reset/replace fuse or breaker.
3.Fill coolant tank with a minimum of four gallons of cutting fluid.
4.Use
5.Pump power supply wires are connected out of phase. Swap any two pump power supply power leads.
6.Tighten any loose fasteners.
7.Remove pump, remove impeller cover, clean and replace as required.
8.Clean/retighten contacts; correct the wiring.

11.Wire motor correctly (refer to inside junction box cover or manual).
12.Reset or replace emergency stop switch assembly.
13.Improve pump motor cooling and airflow. Disconnect machine from power, manually reset thermal relay, and slightly
14.Test/replace transformer.
15.Test all legs for power, test field coil and replace if at fault.
16.Test for shorted windings, bad bearings and repair or replace.
