6 Description and function

6.1 Product description (see Fig. 1)
All pumps dealt with herein are single-stage, low-pressure inline direct coupled
centrifugal pumps, with NEMA standard motor (Fig. 1). The pumps can be
installed either pipe-supported in sufficiently anchored pipework or base-
mounted.
Its capacity can be infinitely varied if used in conjunction with the respective
control devices. This will enable an optimum adaptation of pump performance
to actual load demands and an economical pump operation.
The pump housing is of the inline design with suction and discharge connection
axially in line (Fig. 1).

7 Installation and electrical connection

Installation and electrical work in compliance with any local codes and by
qualified personnel only!
WARNING!
Existing regulations for the prevention of accidents must be observed.
WARNING!
Dangers caused by electrical energy must be excluded.
National Electrical Codes, local codes and regulations must be followed.
CAUTION!
The pump must never be exposed to the weather.
7.1 Installation
Siting in a dry, well ventilated and frost-proofed environment.
Pump to be placed in an easily accessible position in order to facilitate inspec-
tions and repair.
• Minimum space of 15 cm (6 in) between a surface and the motor fan cover.
• Maximum ambient temperature 40 °C (104 °F).
Before pump installation, all welding/soldering on the pipe system must be
completed and the pipe system be flushed out thoroughly to be clear of all for-
eign matter and impurities.
Ensure that the pump is not stressed by the pipework
The pump can be installed in any pipe run course, horizontal or vertical, as long
as the motor does not face downwards. Three pipe diameters of straight pipe is
recommended on the inlet side of the pump.
Arrows at the pump indicate water flow direction through the pump.
It is recommended to provide and install isolating valves at suction and dis-
charge ports of the pump in order to avoid draining to the whole pipe system in
the case of pump inspections or excharge.
