2.3.4 Storage.
2.3.4.1 Temporary storage for up to six weeks-
If the pump unit is not to be used immediately it should be stored carefully in a
horizontal position, in a sheltered, dry location. Additional rust preventive should be applied
to all unpainted carbon steel or cast iron parts and should not be removed until final
installation.
2.3.4.2 Long storage instructions above 6 months & up to 2 Years-
If the pump is not to be installed and operated soon after arrival, store it in a clean,
dry place having slow, moderate changes in ambient temperature. Care should be taken to
protect the pump from moisture, dust, dirt and foreign bodies. It is recommended that
following has to be followed-
a) Ensure that the bearings are packed with the recommended grease, to
prevent moisture entry.
b) Ensure that suction and discharge branches of the pump and all other
openings are covered with cardboard, wood or masking tape to prevent
foreign objects entering the pump.
c) If the pump is to be stored where there is no protective covering, it is
advisable to cover the unit with a tarpaulin or other suitable covering.
d) The shaft should be manually rotated periodically preferably once in a
month to prevent pitting of the bearing surfaces by moisture.
For exposed storage or extreme variants in atmospheric or environmental conditions,
please refer to KBL for special storage instructions to suit the conditions acceptable.
3. PRE-REQUISITES FOR SATISFACTORY OPERATION:
For satisfactory working of the pump insure that the following preliminary conditions are
maintained.
a) Pump handles the liquid as specified in the order.
b) The liquid is free of solid particles since the P.T.F.E (Teflon) bearing life is
greatly affected by solids in the liquid.
c) Minimum submergence is kept as shown in the outline dimension drawing
supplied against the order.
d) Operation & maintenance instructions are followed as given in this
booklet.
e) Load of delivery pipe & other accessories such as sluice valve, reflux
valve, etc. is not coming directly on support plate.
Prior confirmation must be taken from the manufacturer/supplier, if the pump is to be used
for the conditions other than those specified in the order.
4. PUMP HOUSE / TANK LAYOUT:
The layout should be done after considering following-
4.1 Liquid inlet to the tank:
The liquid should enter in the tank such that turbulence, high velocity and air
entrainment are avoided at the suction of the pump.
4.2 Suction tank:
The tank should be designed to be so as to provide-
