Motor/Electrical
Install the motor according to NEC requirements and local electrical codes. The motor should have overload protection.
The use of a power monitor is highly recommended.
Note: All ATEX certified pumps must use a power monitor.
1. The motor must be installed with flexible conduit in order to allow a minimum of 6” of motor movement so that the
pump can be disassembled.
2. Check all electrical connections with the wiring diagram on the motor. Insure that the voltage, frequency, and
horsepower on the motor comply with the line circuitry.
3. If utilized, check that the power monitor has been properly installed in accordance with the manufacturers
directions.
CAUTION: Do not operate the pump to check rotation until the pump is full of liquid.
Pre-Operation Inspection
Prior to the first operation of the pump, perform the following inspections:
WARNING: Lock out power to the driver to prevent accidental motor start-up and physical injury.
1. Insert a screwdriver through the fan cover and rotate the fan. It should move without restrictions.
2. Verify that all flange and hold down bolts are tightened.
Operation
Start-up and Operation
1. This pump must be filled from a flooded suction tank (gravity) or primed with liquid from an outside source.
The ULTRAChem is not self-priming.
2. Ensure that the pump is full of liquid and the inlet (suction) valve is open.
3. Open the discharge valve completely and then close it so that there is no trapped air in the suction and discharge line.
4. After the pump is full of liquid, check that the rotation of the motor/ pump is in the correct direction. This can be
achieved by jogging the motor for approximately 1/2 second. The motor rotation can be observed from the fan end.
Correct rotation when viewed from the fan end is clockwise.
Note: A pump running backwards will pump but at a greatly reduced flow and pressure.
5. Turn the pump on. Slowly open the discharge valve. Check pump for proper flow and pressure, and that
pump runs without excessive noise or vibration.
6. Keep the suction valve in the fully open position. Never use the suction valve to regulate the flow rate. Use the
discharge valve only.
Note: It is not necessary to jog the motor or adjust the valves on subsequent pump starts provided that the pump
and piping remain full of liquid.
