3.1 Handling (Fig: 1& 2 Pg. No. 3&4)
CAUTION! Risk of damage to the pump!
Risk of falling!
Pumps should never be lifted with motor mounted on
motor stool. Lifting lugs provided on motor stool are to
be used only for lifting the pump during maintenance.
Pump to be lifted /inserted in part by part. Safe working
load of wire ropes reduces with increase in included
angle. Never put down or pick up the product when it is
not secured. Tilting of the product should be avoided at
all costs.
Only suitable lifting gear and load carrying equipment
with valid test certificates and adequate lifting capacity
for the loads involved (such as belts/ wire ropes/slings)
should be used for lifting & transporting the product.
If chains are used, they should be secured against slipping
along with protective cover to prevent damage to the
product, paint and/or injury to personnel. When lifting,
care to be taken so that pump flanges, shaft extensions,
suction, bellmouth, etc. are not damaged.

Installation and operating instructions WILO Mather and Platt –VT pumps 19
To lift the pump see lifting diagrams - see also general
safety Information, Point 2). These must have sufficient
load bearing capacity to ensure that the product can be
transported safely.
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
Our vertical pumps require preparation for storage &
regular maintenance during storage. The pump should be
considered in storage when it has been delivered to the
job site & waiting for installation.
It is suggested that the check of parts & material against
the bill of materials be made jointly with the WILO Mather
and Platt’s representative & customer representative.
NO CLAIMS FOR SHORTAGES WILL BE HONORED BY
WILO MATHER AND PLATT, AFTER THE MATERIAL HAS
BEEN PLACED IN STORAGE.
3.3.1 Short-term storage (less than 3 month)
The equipments as shipped should 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.
•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.
•Heavy components must be placed on supports to kept them
off the ground
•Shafting must be removed from the boxes & coated with
preservative, then re-boxed with preservative paper.
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!
3.5 Intended use
The pump supplied is intended for specific fluid. Refer pump
data sheet and order confirmation. For any change in pumped
fluid refer WILO Mather and Platt beforehand. Vertical turbine
pumps are used in water supply, water circulating systems,
injection water, spray pond, condensate extraction, water
treatment, firefighting, booster systems etc. If the operating
conditions are different of the specifications given in the
order, (i.e. type of liquid, temperature or duty point), the end
user must ask a written agreement to WILO Mather and Platt
on the new operating conditions before starting the pump.
