a global opportunity
A Global Opportunity

Worldwide industrial energy consumption is expected to increase by 42%, or an average of 1.3% per year, from 2007 to 2035.

95% of the growth occurs in developing nations.

Global energy consumption rose in 2010 at the fastest pace since 1973, as rapidly growing developing nations led a strong rebound from the Great Recession.

China has now surpassed the United States as the world’s biggest consumer of energy, accounting for 20.3% of global demand compared with 19% for the U.S.



Key Points to Ponder

  • Pumps represent 27% of the electricity used in industrial applications*
  • Energy is the single largest cost-of-ownership component of an industrial pump system – representing between 50-90% of total life cycle costs, dependingon the technology
  • A reduction of energy consumption is a key component to controlling costs
    • Using the right pump technology, properly sized for a specific application, is an important step towards reducing pump energy consumption

Pumps – A Vital Part of an Energy-Efficient System

  • There is a specific “best use” for every pump technology
    • Understanding how pump efficiency, system efficiency and overall energy efficiency are measured and affected by the pumps and overall system configuration is vital to developing a successful energy-efficient pumping system
  • Knowing the fundamental advantages and disadvantages between pump technologies is necessary to selectingthe right pump for optimum performance andenergy-saving results


choosing the right pump technology can help a company achieve simultaneous goals
Choosing The Right Pump Technology Can Help a Company Achieve Simultaneous Goals:

Managing Global Energy Consumption

Global net electricity demand is projected to grow by 1.4% per year between 2007 and 2035, with the strongest growth in developing countries.

The chemical industry made up 22% of the total world industrial energy consumption in 2007. Energy represents 60% of this industry’s operating costs.



Managing Global Energy Consumption

Improving the energy efficiency of even one pump in a manufacturing process could produce substantial financial savings for any operation.

The table to the right summarizes the electrical costs of a continuously operated centrifugal pump (driven by a 100 HP motor) at 10 cents per kWh. Even a 10% reduction in energy consumption adds up to considerable savings.

  • United States
    • 2.4 million pumps consuming 142 billion kWh annually
    • Projected 25% reduction in industrial production energy use by 2017

    • Least energy-efficient economy in the world
    • 0.2% annual projected industrial energy growth
  • Middle East
    • 2.2% annual industrial energy consumption growth rate
    • Chemical sector is the largest consumer of energy
    • Numerous petrochemical projects underway in Saudi Arabia, Qatar, Kuwait, UAE, and Iran



Geographic Opportunities


  • China
    • Industrial sector accounts for 75% of total energy consumption
    • High demand for industrial pumps due to infrastructure development
    • Government mandates dramatic energy reduction in the coming decade
  • India
    • Growth expected from light manufacturing and services
    • Opportunities are abundant as government mandates industries to develop efficiencies in energy consumption

Between 2003 and 2006, this market witnessed rapid growth driven by the huge demand from industries such as water and wastewater treatment, power generation, oil and gas, and chemicals and petrochemicals.



How To Measure Energy Efficiency in Pumps

  • Pumps waste energy when they fail to convert the electric power they consume into the fluid motion they were designed to provide
  • Critical measurement equations used to select a new pump or when analyzing a pump system for energy efficiency:

Imparted Energy

Efficiency =

Inputted Energy

Energy Used

Specific Energy =

Pumped Volume

Energy Converted

Power =

Time Taken



How To Measure Energy Efficiency in Pumps

kW x Efficiency


(alternating = current)




(1 - 0.55)


Savings = 235 kW x 6,000 Hrs/Yr x = 415,769 kWh per year @ 0.05 per kWh = $20,788 Savings

Measuring & Managing Energy Consumption

  • When pumps operate at optimum levels they use less energy and increase reliability, saving both energy and maintenance costs
  • The maintenance and productivity benefits of improving a pump system’s performance are generally one to two times the value of the energy savings

Calculating Potential Energy Savings

(1 − Actual System Efficiency)

Savings = kW (in input electric energy) x Annual Operating Hours x

Optimal System Efficiency


1) Operating Efficiency (300 HP pump = 55% Efficiency)

2) Optimal Operating Efficiency (300 HP = 78% Efficiency)

3) Pump draws 235 kW x 6,000 hours of service per year



Reducing Energy Waste Begins with Proper Pump Selection for the Application

  • Select the pump technology best suited for the application
  • Properly size pumps, control valves and piping for real-time requirements (avoid excessive margin of error capacity and/or total pressureor head)
  • Reduce restrictions, turbulenceand frictional losses



Reducing Energy Waste Begins withProper Pump Selection for the Application

  • Ensure proper motor alignment (poor alignment of motor and load increases motor power consumption)
  • Reduce flow rates = lower energy losses
  • Lower operating pressures
  • Maintain pumps and system components to avoid efficiency loss (wear is a significant cause of decreased pump efficiency; corrosion in pipes increases friction)



Consider Application When Choosing Pumping Equipment

    • Maximum VISCOSITY of the liquid in Seconds Saybolt Universal (SSU)
    • Approximate DELIVERY required in gallons/litresper minute
    • Differential PRESSURE required in pounds per square inch (PSI) or Bar
  • HOW HOT?
    • Pumping TEMPERATURE of the liquid in degrees of Fahrenheit or Centigrade
    • SUCTION conditions when pumping in vacuum, or PSI/Bar for pressure
    • Type of LIQUID to be handled
    • Specific GRAVITY of the liquid
    • Type of SERVICE, e.g., intermittent duty, semi-continuous duty, or continuous duty



Many pump users do not know how to properly select and apply pumps to a system, so pump system operating costs are inadvertently increased as a result.

  • Using pump selection software programs can help operators optimize pump selection
  • Leading pump manufacturers also provide applications and engineering expertise, pump specification and selection programs, technical training and support

allows users to select pump data and pump curves so they can select the proper positive displacement or centrifugal pumps for their application.

It’s time to put some energy into learning about the energy-saving advantages of positive displacement sliding vane pumps

  • There is no “one-pump-fits-all” solution
  • The right pump delivers productivity gains and helps control energy consumption
  • Positive displacement sliding vane pumps, by virtue of their inherent energy and mechanically-efficient designs, are uniquely suited to offer manufacturers immediate advantages in performanceand energy savings



Using LCC (Life Cycle Costs) for Proper Pump Selection

LCC – Relative ComparisonCentrifugal vs. Positive Displacement (PD) Pumps

  • An analysis of Life Cycle Costs (LCC) can dramatically reduce waste and maximize efficiency
  • The NET cost savings based on LCC will often justify a higher initial price for a more energy-efficient pump
  • Life-cycle costing helps identify the lowest total cost of ownership by considering:
    • Initial equipment cost
    • Installation and Commissions
    • Energy costs
    • Maintenance and Repairs
    • Downtime costs
    • Decommissioning costs

Consider Positive Displacement Pumps over Centrifugal Pumps when:
  • Working fluid is highly viscous (over 850 cSt)
  • Flow rate must be predictable over a wideflow range (flow must be metered orprecisely controlled)
  • Flow rate must remain constant under varying system pressures
  • System requires high-pressure, low-flow
  • Line stripping is required (some PD technologies)
  • Suction lift or self-priming is required
  • Working fluid is shear-sensitive
  • Energy-savings/efficiency is a primary concern


positive displacement pumps are not created equal
Positive Displacement Pumps Are Not Created Equal
  • PD pumps make up approximately 15% of industrial pump population
  • There are significant differences between PD pump types

Improper pump selection can cost money in downtime, lost production, maintenance costs and energy consumption.
