water transfer and boosting

Water transfer and boosting applications are numerous and cover market sectors ranging from water utilities, commercial, industrial and agricultural. All applications are different but all share the common desire to provide a practical pumping system which is the most efficient and can provide the best whole life cost whilst reducing energy consumption. The awareness of this has been considerably raised in recent years by the introduction of the enhanced capital allowance scheme which allows companies to write off 100% of their investment against their taxable profits by installing approved energy saving plant and machinery.

Some facts:

  • The average electric motor will consume its capital cost in energy in less than 2 months
  • When a motor is rewound its efficiency is reduced - consider the benefits of life cost when thinking about possible motor rewinds consider new EFF1 electric motors
  • Pumps represent the largest single motive power in industry and commerce, energy usage by motor driven equipment attributed to pumps is over 30%
  • The cost of pumping is widely accepted to be represented by the following; 85% Energy Consumption, 8% Capital Cost, 7% Maintenance
  • A 20% reduction in speed can save 50% of the electrical energy absorbed

At Panks Engineers Ltd we will assess your requirements and supply what we feel is the best solution whilst utilising the latest economical products available.

The provision of packaged booster sets or design and build to suit on-site requirements are both possible. Fixed speed and variable speed options.

Potential Benefits of Variable Speed Controlled Pumps

  • Reliability improvements
  • Simplified pipe systems - elimination of control valves and by-pass lines
  • Soft start and stop reduced surge and kind on poor power supplies
  • Reduced maintenance
  • Energy saving
  • Comfort - Optimum adaptation to varying requirements. Any duty point can be met.
  • Constant Pressure or Constant Flow options
  • Control - easier and more accurate to set up and monitor. More flexible
  • On a poor power supply - VSD pulls no more than FLC.
