This document discusses the development of smart pump technology that applies artificial intelligence to fluid handling systems. It aims to reduce energy usage by allowing pumps to operate in either an open or closed loop. In open loop, pumps run at a minimum speed and pressure when fluid is being circulated but not used. In closed loop, pumps maintain required pressure but only supply needed flow. This saves significant energy compared to traditional pumping methods. The technology was inspired by turning a tap on and off to minimize water usage. It has benefits like accommodating various materials, preventing paint shear, being low maintenance, and using no consumables. An electric drive pump was chosen over pneumatic due to more direct energy efficiency. Testing confirmed the smart pump saves substantial energy

2. DEFINITION OF “INTELLIGENCE” :
“Intelligence has been defined in different ways, including the abilities for abstract
thought, understanding, …and problem solving.
Intelligence is most widely studied in humans, but has also been observed in animals and
plants.
Artificial intelligence is the intelligence of machines or the simulation of intelligence in
machines.”

3. What is the need for an intelligent fluid handling system?
Many organizations have a growing concern for the environment.
Businesses play a critical role in developing and utilizing environmentally sound products.
Awareness of the impact fluid handling equipment can have on the environment to find
ways to reduce negative effects.
• Reduction of Energy
• Compliment with governmental regulations
• Customer demands for eco‐friendly technology
• Appealing to green philosophies
• Protecting the environment
• Reducing waste

to create energy saving simply by using less energy.

7. This gave the initial idea to develop a fluid handling system, capable of…
…“Turning on and off the tap” self sufficient.
The patented SMART control:
”Tap OFF mode” ‐ OPEN LOOP
when paint needs to be circulated but is not required at any take off point.
”Tap ON mode” ‐ CLOSED LOOP
when paint is required
maintain required pressure but only supply the flow needed at the user points

10. Smart Control
The ‘Smart’ system design provides for
two modes of operation.
Open Loop
‘unload’ the back pressure regulator to
reduce the paint line pressure
pump motor will be driven to run at a
pre-set minimum
Closed Loop
Paint pressure maintained by the back-pressure regulator

monitored at the pump by a pressure sensor

11. Continue the natural thoughts
Analysing and understanding the process was the key.
Target was to overcome all of the todays known concerns when thinking of fluid handling:
• Works for widest possible range of materials
• No paint shear
• Low maintenance
• No consumables

12. Logical conclusion
The need to save energy in pumping paint meant that electrical drive was
the only logical choice.
