Energy Audit - Pumps

Many pump systems waste energy and money day after day. And you can determine whether your system is one of them. A pump audit will tell you exactly how much you could save by optimizing your system. And then you can achieve those savings.

What's Pump Audit?

Simply put a pump audit is a check up of your pump system. It checks the overall efficiency of your pumps and reveals how much energy could be saved by switching to a different pump pipe line changes / modification. What is more, it clearly shows the monetary impact of those savings. Because what one can believe that energy conservation is most efficient when it benefits everyone.

Why Save energy ?

• Energy is one of the key barometers in identifying a country's economic development and hence the more energy saved improves the country's security as also economy.
•  Higher energy needs results in huge investments in the form of setting up power plants etc. 
• Depleting natural resources; Oil will last for 45years, Gas 65years and Coal over 200 years - is quite disturbing and thus the need to save energy becomes inevitable.
• Its an initiative for a clean, green and sustainable environment.

 

Why Pump Audit ?

• While industry consumes 50% of the total energy expended, 20% of this is consumed by pumps.
• 30-50% of this energy guzzled by pumps can be saved.
• The life cycle cost of a pump reveal that the energy costs eats away 85%, maintenance costs 10% and the initial investment of the product meagre 5%

Below are the reasons which shows that the pump become a prime candidate for energy audit in the drive for energy conservation.

• Old inefficient pump
• Overdesign
• Improper layout
• Improper selection and operation

 

HOW TO FIND THE TRUTH

A pump audit  involves very little effort on your part thanks to the latest technologies. The pump auditing team will bring everything in one suitcase. And they will attach measuring equipment to your system, wait for the necessary data to be recorded, analyze the information and prepare recommendation for you.

The practicalities of pump audits

When it comes to carrying out the actual pump audit, many companies distinguish between three different measuring categories. which are follow 

1. Countable values like flow and energy consumption 
2. analogue values like pressure, temperature, water level
3. incident rates such pump on/off and valve open/closed

Together, this information allows auditor to form an accurate image of the system's energy consumption. Each area is covered by special equipment.

Instruments used in energy audit

Many of the companies which are in to the field of energy audit use various equipment like flowmeter, pressure gauge (Calibrated), ammeter, voltmeter or power analyzer.

Process of energy audit 

1. Short list the pumps for audit.
2. Measurement of flow
3. Measurement of pressure (Suction and Discharge)
4. Measurement of energy consumption
5. Calculating the systems efficiency
6. Discussion with site engineer
7. Mutually Finalizing the parameter
8. Data analysis and recommendations (Piping modification if required)
9. Final report 

What you can save?

A pump audit helps you take affirmative action in order to save energy. The pump audit tells you exactly how much you could save with new and more efficient pump and how long it takes to see a return on your investment.

You can cut your energy costs in half

When energy accounts for a staggering 85% of the total cost, that's where you can achieve real savings. In many systems, more than half of all the energy consumed by the pumps could be saved. Yes, more than half. It's not just something - it's something some of pump auditing companies have proven.

Shorten your payback times

The reduced energy costs alone mean that new pumps can pay for themselves in very little time. In each case, the pump audit report will show the exact number of months, usually around 18 to 20. After that, the savings translate into pure profit for you. Year after year.
