Pumps for new energy production

Reliable pump selection for new energy production processes

Iwaki pump solutions for energy-efficient and new energy production applications

Supporting fluid handling, dosing, circulation and recovery duties in hydrogen production, fuel cell, battery, CO₂ recovery and solar production applications

New energy production processes often depend on reliable fluid handling in the background. Pumps may be needed to circulate electrolytes, transfer pure water, support cooling and heat recovery, dose or fill process fluids, move coating liquids, recover solvents, or circulate absorbent liquids.

Sensys supplies Iwaki pump solutions for demanding chemical handling and process applications, helping customers select equipment that is appropriate for the fluid, duty, installation environment and long-term maintenance requirements.

In hydrogen production, fuel cell systems, battery manufacturing, CO₂ separation and recovery, and next-generation solar cell production, the right pump choice can support reliable operation, safer fluid handling, improved maintainability and lower lifecycle risk.

Why pump selection matters in new energy applications

Pumps are often small parts of a much larger process, but poor pump selection can create avoidable maintenance burden, reliability issues and operational risk.

An oversized, poorly matched or unsuitable pump can increase wear, heat generation, chemical waste, downtime and unplanned intervention. In high-risk or technically demanding environments, these issues are rarely just inconvenient. They can affect process continuity, safety, compliance and total cost of ownership.

Selecting the right pump for the duty helps support:

  • Reliable chemical transfer, dosing or circulation
  • Reduced wear and maintenance intervention
  • Better process control and repeatability
  • Longer equipment life
  • Lower lifecycle cost
  • Improved plant resilience
  • Safer handling of aggressive or sensitive fluids
  • More efficient operation within the wider process

For blue-chip and high-risk organisations, pump selection is not only an engineering issue. It is a business continuity, compliance and reputation issue.

New energy applications where pump selection matters

Across new energy and energy-transition processes, pumps often sit quietly in the background. But their role is important. They keep liquids moving, support controlled dosing or filling, help manage cooling and heat recovery, and contribute to reliable, repeatable process performance.

Iwaki pump technologies are used across a range of demanding process duties, including electrolyte circulation, pure water transfer, cooling circulation, waste heat recovery, coating liquid delivery, electrolyte filling, solvent recovery and absorbent liquid circulation.

For organisations working in high-risk or technically demanding environments, the right pump choice can support lower lifecycle cost, reduced maintenance burden, safer fluid handling and more reliable operation.

Hydrogen production and electrolysis applications

Hydrogen production involves several fluid handling duties around the electrolyser and supporting process equipment. Pumps may be required to keep electrolyte moving, transfer pure water, support cleaning tower circulation, and help manage wider process duties around purification and heat exchange.

Relevant pump duties may include:

Electrolyte circulation
Pure water transfer
Cleaning tower circulation
Chemical handling around hydrogen and oxygen gas treatment systems
Process support for water purification and heat exchange

In this type of application, pump selection needs to take account of chemical compatibility, reliability, pressure requirements, maintainability and the wider process environment. A well-matched pump helps support stable operation and reduces the risk of avoidable maintenance or process interruption.

Fuel cell systems and heat recovery

Fuel cell systems rely on supporting pump duties for water injection, cooling, waste heat recovery and gas-liquid transfer. In compact equipment, pump selection can affect not only fluid movement, but also space, power use, control and long-term maintainability.

*Both PEFC and SOFC are available. The above figure shows the flowchart of PEFC.

Relevant pump considerations may include:

Long-life pump options
Low power consumption designs
Compact and lightweight equipment integration
Speed control through brushless DC motor technology
Pump options for cooling water, waste heat recovery and gas-liquid transfer

Compact, long-life and low-power pump options can be especially useful where pumps need to be integrated into equipment with limited space, controlled output and reliable performance expectations.

Battery production and energy storage applications

Battery manufacturing and energy storage applications can involve a wide range of fluid handling requirements, from material transfer and coating through to electrolyte production, filling, recovery and circulation.


Relevant pump duties may include:

Positive and negative electrode material handling
Electrolytic solution production
Electrolyte filling
Solvent recovery and recycling
Redox flow battery electrolyte circulation
Separator coating and material transfer

In these processes, pump choice can affect consistency, maintainability, chemical handling, process control and production reliability.

CO₂ separation and recovery applications

CO₂ separation and recovery processes can involve the circulation of absorbent and regenerant liquids, including amine-based solvents in chemical absorption systems. These duties place clear demands on material compatibility, containment, pressure and temperature capability, and long-term reliability.


Relevant pump considerations may include:

  • Corrosion resistance
  • High pressure and temperature capability
  • Sealless operation
  • Leak prevention
  • Compact integration into process equipment
  • Safe handling of absorbent and regenerant liquids

Sealless pump options can be particularly relevant where leakage risk needs to be carefully managed.

Perovskite solar cell production

Perovskite solar cells are being developed as a next-generation solar technology, with coating processes playing an important role in research, development and mass production.

Relevant pump requirements may include:

  • Accurate fluid delivery
  • Low pulsation
  • Gentle handling of sensitive or foaming fluids
  • Easy disassembly and cleaning
  • Suitability for research, trial and mass production environments

For research, development and mass production environments, accurate delivery, gentle liquid handling, cleanability and repeatable performance are all important.

Relevant Iwaki pump technologies

Depending on the application, suitable Iwaki technologies may include:

  • Magnet drive pumps
  • Stainless steel magnet drive pumps
  • Motor driven metering pumps
  • Direct drive pumps
  • Air driven diaphragm pumps
  • Chemical gear pumps
  • Hi-Cera pumps
  • Air pumps
  • Flow control and water quality control equipment

The right choice depends on the fluid, flow rate, pressure, temperature, chemical compatibility, installation environment, control requirements and maintenance expectations.

Sensys can help customers review the application and select the most appropriate pump technology for the duty.

Efficiency in new energy applications is not only about power consumption

In new energy production, efficiency is not always limited to electrical consumption. Depending on the application, the bigger gains may come from reliable circulation, accurate dosing or filling, reduced waste, lower maintenance intervention, compact equipment integration, safer fluid handling and longer service life.

A well-selected pump can help reduce:

  • Overworking of equipment
  • Recirculation losses
  • Unnecessary maintenance visits
  • Chemical waste
  • Leakage risk
  • Process interruptions
  • Equipment replacement frequency
  • Operator intervention

That is why pump selection should consider the full operating context, not just the initial purchase price or headline power rating.
