3.2 Delivery
On arrival, the delivered items must be inspected for
damage and a check made that all parts are present. If any
parts are damaged or missing, the transport company or
the manufacturer must be informed on the day of delivery.
Any claim made at a later date will be deemed invalid.
Damage to parts must be noted on the delivery or freight
documentation.
3.3 Storage
3.3.1 Short-term storage (less than 3 month)
The equipment as shipped have adequate protection for
short-term storage in a covered, dry and ventilated
location at the job site prior to installation.
• If the pump is not installed immediately after delivery, it
must be stored in a dry and clean place with sufficient
ventilation, no vibration, no freezing and the temperature
variations must be smooth.
• Bearings and couplings must be protected against sand,
dust and foreign bodies. To avoid corrosion and jamming,
please lubricate the pump and make turn the rotating
elements for several turns at least once a week.
• Pre-packed desiccants may be used to absorb moisture &
keep the pump dry. It must be removed before putting the
pump on operation.
3.3.2 Long-term storage (more than 3 month)
If the equipment will be subject to extended storage
condition prior to installation, then the manufacturer
must be informed about storage duration, so that special
protection can be recommended.
• Place the MISO / PISO pumps horizontally on firm
foundation and secure it against falling.
• The machine must be protected from direct sunlight, heat,
dust, and frost.
• The rotors or propellers must be turned at regular intervals.
This prevents the bearing from locking and the film of
lubricant on the mechanical shaft seal is renewed.
• For mechanical seal, we recommend: relative air humidity
below 65%, temperature between 15°C and 25°C. Direct
exposure of the mechanical seal to heat (sun, heating) as
well as to ozone, present or produced by ultraviolet light
(halogen or fluorescent lamps), must be avoided because
of the risk of embrittlement of elastomeric materials.
3.4 Pump returning back to the supplier
Products, which are delivered back to the plant, must be
clean and correctly packaged. In this context, clean means
that impurities have been removed and decontaminated if
it has been used with materials, which are hazardous to
health.
The packaging must protect the product against damage.
CAUTION! Guarantee not applicable!
Products, which are not suitably packaged for delivery
back, are no longer covered by guarantee!
