100 |
|
- |
8.1.2(The multi-stage pump shaft may be guided through bearings, the bearings may be provided in stage casing, suction housing and
discharge casing, while in case of intermediate bearings, suitable positions may be selected in the overall span.) |
- |
100 |
|
- |
8.1.3(The pump may be equipped with replaceable bearing and wearing ring, wherever provided.) |
- |
100 |
|
- |
8.1.4(The strainer on the suction shall offer the best compromise amongst restraining large solids from entering the pump and containing
the suction losses to the minimum.) |
- |
100 |
|
- |
8.1.5(The pump shall be capable to give discharge without overloading the prime mover within the permissible current at rated voltage
and supply frequency at minimum +5 percent and minimum –15 percent of the guaranteed duty point head up to 30 m.
Above 30 m, the pump shall be capable to give discharge without overloading the prime mover within the permissible current at rated
voltage and supply frequency at minimum +10 percent and minimum –25 percent of the guaranteed duty point head.) |
- |
100 |
|
- |
12(Cable) |
- |
100 |
|
- |
12.1.2(The size of the conductor shall be adequate and suitable for contineous use under water and in air.
the length of the cable shall be minimum 2 m externallly unless otherwise specified by the customer) |
- |
100 |
|
- |
12.1.3(The size and of the cable should be suitably selected so that the voltage drop between control panel and the mptor terminal does
not exeed three percent of the rated voltage) |
- |
100 |
|
- |
12.1.4(In case a joint is required to be made between the lead cable supplied with the motor and the user’s cable, a detailed procedure to
make water tight joining shall be supplied by the motor manufacturer.) |
- |
100 |
|
- |
12.1.5(If four core cable is used, the fourth core is to be used for earthing.) |

16.1(Guarntee of Performance) |
- |
100 |
|
- |
16.1.1(The pumpset shall be guaranteed for their performance of the nominal volume rate of flow and the nominal head at the guaranteed
duty point. The overall efficiency of the pumpset shall be guaranteed at the declared duty point only.) |
- |
100 |
|
- |
16.1.2(The guarantee shall be deemed to have been met with, if the measured values of head, volume rate of flow and overall efficiency
are within the indicated in IS 11346 limits) |
- |
100 |
|
- |
16.1.3(Open well submersible motor shall not get overloaded in the specified operating head range at rated voltage and supply frequency.) |
- |
100 |
|
- |
16.1.4(The pump shall be tested for the operating head range as per 8.1.5.) |
- |
100 |
|
- |
16.1.5(The overloading of motor is that condition when maximum current drawn by the motor exceeds the limit of 1.07 times of the rated
motor current) |
- |
100 |
|
- |
16.1.6(The tolerance shall apply to guaranteed duty point only.) |
- |
100 |
|
- |
16.1.7(Performance at rated voltage and supply frequency is actual performance of the set. This is better than performance at rated speed,
since in the entire operating head range speed of motor is higher than rated speed, as motor is running in under loaded condition.) |
- |
100 |
|
- |
16.1.8(The manufacturer shall specify the minimum submergence of pump unit at duty point.) |
