INSTALLATION ON SITE
Installation of the pump on site and levelling and adjustments of it should be performed only by
qualified personnel. Improper installation may cause failure. Such situations are excluded from
warranty.
Installation on site should be performed as per EN 60204-1 standard.
4.1- Bare Shaft Pump
• If the pump is supplied without motor, proper motor should be selected before the group is installed.
• Following points should be taken into consideration when selecting motor:
- Maximum power drawn by the pump along the entire operating range,
- Running speed of the pump,
- Applicable power supply (frequence, voltage, etc.),
- Motor type (TEFC, Exproof, etc.),
- Motor connection form (pedestal, flanged, horizontal, vertical, etc.), and
4.2- Preparation for Installation
Prior to installation of the pump in place:
• Suction and delivery flanges should be cleaned thoroughly.
• Never use the pump as a point of support or bearer for the piping system.
4.4- Installation of the Piping System
4.4.1- General Warning
ATTENTION
• The pump should be installed at a well-ventilated place free of freezing and explosion risk.
• There should be sufficient space around the pump being installed to allow easy access for
maintenance of the pump as well as sufficient space above the pump to hoist it when required.
• Suction pipe of the pump should be short as far as possible.
• The piping system should be supported at points near to the pump. For this purpose, after completion
of the installation of the piping system, loosen the bolts of the suction and delivery flanges and
control whether the piping system applies any tension on the pump.
• Rated diameter of the suction and delivery flanges of the pump are not indicator of the correct
sizes of the suction and delivery pipes at all. The rated diameter of the pipes and accessories used
should be equal to or larger than the inlet diameters of the pump at least. Never use pipes and
accessories having smaller diameter than the inlet diameters of the pump.
Especıally components
such as bottom valve, strainer, dirt-retaining filter and check valves with larger free passage area
should be preferred. In general, flow rates should not exceed 2m/s for the suction pipe and 3m/s for
the delivery pipe. High speeds cause high pressure reduction and it, in turn, cause cavitation conditions
on the suction pipe and loss arising from excessive friction on the delivery pipes.
