European Union Pump Efficiency Regulations for Centrifugal Pumps

Pump Power Monitor for European Union Regulations

Introduction

• CO2 contributes to the Green House Effect and is
  a by product of Electricity production by burning
  fossil fuels.
• European  Union in a bid to emerge as a
  climate-friendly region is cutting down power
  consumption.
• Thus EU has rolled out the European Union Pump
  Efficiency Regulations which are also applicable
  to Centrifugal Pumps. These pumps deal in pumping
  fluids and consume considerable amount of power
  in converting kinetic energy of a flowing fluid
  (velocity pressure) into static pressure.

EU Directives

• To keep a check on Power consumption and in a bid
  to move towards higher efficiency pumps certain
  provisions of the EU Motor efficiency Directive
  relate specifically to the pump industry.
• In addition to other factors these directives
  specify that energy consumption must comply to
  the specifications mentioned in the table below

Problem

• Though there is no dearth of Centrifugal Pumps
  that are compliant with EU Regulations.
• However, what is challenging is that the pumps do
  not remain compliant to consuming less energy
  over their life cycle which is about 13 years.
  Over time due to several reasons these pumps
  begin to consume more electricity than was
  planned.
• As a result they not only become noncompliant to
  EU Directives which can attract huge audit fines
  but also power consumption expenditure of end
  user goes up.

Reason why Pumps begin to consume more
electricity

• To cover a much wider range of duties the same
  pump can be offered with different impellers or
  with different speed motors. This can lead to a
  significant decrease in efficiency as the pump is
  operating away from the designed Best Efficiency
  Point (BEP). This will result in higher energy
  costs and greater energy consumption.
• Pump performances and efficiency deteriorate over
  time. Pumps incur corrosion, abrasion, erosion,
  and aging which is a result of fluctuating liquid
  level, gas level, chemical level, temperature and
  more. If pumps are operating outside the point of
  best efficiency not only the efficiency
  decreases, but shafts and bearings suffer damage
  and the chance of a breakdown becomes extremely
  high.

Technological Solution

• An IIoT Platform can be used to ensure approved
  level of power consumption at all times as well
  as monitor wear and tear, gas levels, chemical
  levels etc. that contribute to wear and tear that
  leads to increased power consumption.
• Such an IIoT platform consists of three
  significant parts
• Sensors, including cables and junction boxes
• Data collection device
• Monitoring/analysis software
• Some of the sensors that can be used for this
  type of monitoring are Magnetic sensors, Gas
  Sensors, Chemical Sensors and more.

Benefits to Pump Manufacturers/ Rentals and users
outside Europe.

• Compliance with these standards mean less
  electricity consumption and lower expenses for
  end user. Thus Pump Manufacturers in other
  countries, can gain a competitive edge when they
  are able to provide their customers a cost saving
  solution.
• Most countries are expected to follow suit with
  the EU Compliance standards and manufacturers and
  Rentals will face minimum business disruptions
  when these regulations are implemented elsewhere.
