Over 68ºC the operator should take protective measures and place warning notices advising of the
danger which exists if the pump is touched.
The type of protection selected should not isolate the pump entirely. It should allow for the bearings
to be cooled more efficiently and for the bearings to be lubricated.
5.5. PIPES
•
As a general rule, install the suction and discharge lines in straight sections, with the minimum possible
number of elbows and fittings in order to reduce any pressure losses that may be caused by friction.
•
Make sure that the pump’s ports are properly aligned with the pipework and have a diameter similar to that
of the pump connections.
•
Place the pump as close as possible to the suction tank and whenever possible below the liquid level, or
even below the tank level in order to achieve the largest possible static head for suction.
•
Install support brackets for the lines as close as possible to the pump’s suction and discharge ports in order
to avoid vibrations and stress on the pump.
5.5.1. Shut-off valves
The pump may be isolated for maintenance. To accomplish this, shut-off valves must be installed and
connected to the pump’s suction and discharge connections.
These valves must ALWAYS be open during operation of the pump.
5.6. ELECTRICAL INSTALLATION
Only qualified personnel can connect the electric motors.
Take the necessary measures to prevent damage to cables and connections.
Electrical equipment, terminals and components of the control systems may still carry current when
they are disconnected. Contacting them may impose a hazard to operators or cause irreparable
material damage.
Before handling the pump, make sure that the motor is stopped.
Connect the motor in accordance with the instructions supplied by the motor manufacturer, in accordance
with the current national legislation and in compliance with EN 60204-1.
Check the direction of rotation (see the signalling label on the pump).
Start and stop the pump motor momentarily. Make sure that the direction of rotation is correct. If the pump
rotates in the wrong direction it could cause serious damage.
See indicator label on the pump.
ALWAYS check the direction of rotation of the motor with liquid inside the pump.
