Technical Specifications
. INOXPA cannot be held responsible for the improper
use of the equipment.
NEVER touch the pump or the pipes if hot liquids are being pumped.
Checks before starting up the pump
Fully open the shut-off valves on the suction and discharge pipes.
If liquid does not flow into the pump, fill it with the liquid to be pumped.
The pump must NEVER rotate without a liquid inside it.
Check that the direction of rotation of the motor is correct.
Checks to be carried out when starting up 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. Check the curve to determine the
minimum pressure required above the vapour pressure (NPSHr).
Control the discharge pressure.
Check that there are no leaks through the sealed areas.
Do not use a shut-off valve to regulate the flow in the suction pipe. 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.
When the sound pressure level in the operating area exceeds 80 dB(A), appropriate personal protective
equipment must be used.
