5.4.1. Excessive temperatures
Depending on the fluid to be pumped, high temperatures can be reached inside and around the pump.
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. MECHANICAL SEAL WITH QUENCH
Models with mechanical seal with quench may require the inlet and outlet connection to the cooling liquid.
See the limits of water consumption and pressure from the cooling circuit in chapter
