The mounting of the pump or pump unit should be solid and stable. Pump
orientation must be considered in relation to drainage/cavity ventilation
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
and will create high temperatures and increased noise emissions. 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 3.5 and 6.3). Beware of over/under filling the gearbox as this could cause the
pump to overheat and 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 an
ignition source.
Be sure that pump rotation is correct for the desired direction of flow (refer to section
3.5).
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 can 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 base plate. If pump is base plate 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 6.4.
DO NOT attempt any maintenance or disassembly of the pump or pump unit without
first ensuring that:
