6. Start-up
Before starting the pump, carefully read the instructions in section
. INOXPA will not be liable for improper use of the
equipment.
NEVER touch the pump or the lines if hot liquids are being pumped.
6.1. CHECKS BEFORE STARTING THE PUMP
•
Completely open the shut-off valves on the suction and discharge lines.
•
If liquid does not flow towards the pump, fill it with the liquid to be pumped.
The pump must never turn dry.
•
Check that the power supply matches the rating indicated on the motor plate.
•
Check that the direction of rotation of the motor is the right one.
6.2. CHECKS WHEN STARTING THE PUMP
•
Check that the pump is not making any strange noises.
•
Check if the absolute inlet pressure is sufficient to prevent cavitation in the pump. See the curve to determine
the minimum pressure required above steam pressure (NPSHr).
•
Control the discharge pressure.
•
Check for leaks in the sealing areas.
Shut-off valves on the suction pipe must not be used to regulate the flow. All shut-off valves must be
fully open during operation.
Control the motor consumption to prevent an electrical overload.
Reduce the flow rate and the electrical power consumed by the motor:
•
by regulating the pump’s discharge flow
•
by decreasing the motor speed
