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 t
hat 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.
5.5.2. Pressurisation tank
For models with a double mechanical seal a pressurisation tank needs to be fitted
ALWAYS install the pressurization tank at a height of between 1 and 2 meters with respect to the
pump shaft.
ALWAYS connect the coolant inlet to the bottom connection on the seal chamber. The coolant will
then exit through the top connection on the chamber. See the follow figure.
For more information on the pressurization tank (installation, performance, maintenance, etc.), refer to the
instruction manual supplied by the manufacturer.
5.6. ELECTRICAL INSTALLATION
Only qualified personnel can connect the electric motors.
Take the necessary measures to prevent damage to cables and connections.
