Value for money
Kirloskar pumps begin from MRP: Rs 4,225 and keep on increasing as per size and specifications of the pumps and Ellen pumps too fall in the same category. Neither is more or less competitive and both have a more or less the same niche market and provide equal value for money charged.
Next we thought of comparing it on other parameters like efficiency,
noise, self-priming time, heating , etc.
As an industry standard for such pumps, we know that a rated
frequency, the pump should give a minimum of 90 per cent of rated
total head at a minimum of 90 per cent of rated discharge. The pump should not take more than 110 per cent of the declared power input at the guaranteed duty point. The motor should not get overloaded in the operating head range of +- 25 per cent of rated head at rated voltage when the supply frequency is within the limits (+- 3 per cent of the rated frequency). The maximum allowable current should be 1.07 times of the declared full load current. Both Ellen and Kirloskar pumps gave the same efficiency.
u Rated Total Head
All the Ellen branded pumps passed in the rated total head but
Kirloskar scored the highest points and was the most efficient of the

consumption can be substantial. Overall efficiency of the tested pump sets varied from 9.37 per cent to 13.73 per cent. Higher efficiency is considered better in terms of higher water output with low power consumption. In this regard, Ellen pumps did better than Kirloskar.
u ‘No Load’ Test
u High Voltage Test

voltage was measured to check how the pump behaves with changes in voltage, whether it gets all heated up or is able to function
optimally. The lower the temperature rises the better it is for
maximum performance of motor. For temperature at rated voltage, the top scorer was Kirloskar pumps but for temperature at reduced voltage, the top score was Ellen pumps.
u Noise Level and Vibration Measurement Test

strong points and although both brands are respected in the market, the customer has to make a smart choice based on the specific
requirements that he/she needs.• In overall efficiency (high water output at low energy consumption),
Ellen pumps performed on better than the Kirloskar pumps when we tested the two.• In pump performance and amount of water output, Kirloskar topped way ahead of Ellen pumps.
• Most of the brands do not attain the declared rated load of 0.37
kilowatts or 0.5 horsepower, but Ellen pumps did reach the rated load.
• The pumps of brands Ellen and Kirloskar were both ISI-marked.
• Kirloskar had 18 and 15 months’ warranty, respectively, while
Ellen gives 12 months’ warranty and free servicing .
• Ellen pumps produced higher noise levels (88.0), while Kirloskar
made the least noise.
• Kirloskar showed maximum vibration (0.7 mm/sec) whereas Ellen pumps were amongst the lowest vibrations creation levels.
• Kirloskar pumps are still more expensive than Ellen pumps due to
brand pricing and advertisement costs, but otherwise Ellen pumps are more affordable and economical overall.
