The mounting of the pump or pump unit should be solid and stable. Pump

orientation must be considered in relation to drainage requirements. Once

mounted, shaft drive elements must be checked for correct alignment. Rotate

pump shaft by at least one full revolution to ensure smoothness of operation.

Incorrect alignment will produce excessive loading, create high temperatures

and increased noise emissions. Do not use any drive arrangements, which

cause side loading of the drive shaft. It may also be necessary to earth the

pump head to avoid the build up of a potential charge difference that could

cause a spark.

The installation must allow safe routine maintenance and inspection (to

replenish lubricants, check for leakage, monitor pressures, etc.) and provide

adequate ventilation necessary to prevent overheating.

Fill all gearboxes with the recommended grades and quantities of lubricant;

(refer to section 5.3). Beware of over/under filling the gearbox as this could

cause the pump to over heat and severe mechanical damage to occur.

Before operating the pump, be sure that it and all parts of the system to which

it is connected are clean and free from debris and that all valves in the suction

and discharge pipelines are fully opened. Ensure that all piping connecting to

the pump is fully supported and correctly aligned with its relevant connections.

Misalignment and/or excess loads will cause severe pump damage. This

could result in unexpected mechanical contact in the pump head and has the

potential to be a source of ignition.

Be sure that pump rotation is correct for the desired direction of flow; (refer to

section 3.1).

Do not install the pump into a system where it will run dry (i.e. without a

supply of pumped media) unless it is equipped with a flushed shaft seal

arrangement complete with a fully operational flushing system. Mechanical

seals require a thin fluid film to lubricate the seal faces. Dry running will cause

excessive heat and seal failure

Pressure gauges/sensors are recommended, next to the pump suction and

discharge connections to monitor pressures.

Caution must be taken when lifting the pump. Suitable lifting devices should

be used as appropriate. Lifting eyes installed on the pump must only be used

to lift the pump, not pump with drive and/or baseplate. If pump is baseplate

mounted, the base plate must be used for all lifting purposes. If slings are

used for lifting, they must be safely and securely attached. For weights of bare

shaft pumps refer to section 5.5.
