Wilo launches the Stratos-MAXO – the world's first "true" smart-pump

Gary Wheatley – Wilo UK’s Training and Technical Manager, says the new Wilo Stratos-MAXO will take pumps to the next level.
We live in a world where exaggeration is common place, and words like ‘legend’ and ‘unique’ are over used. Even the word ‘smart’. What does it mean, particularly in regard to today’s pump technology? Is it simply clever? Or is it more than that?
There is, I think, a need to re-define ‘smart’ to ensure that anyone looking for true ‘smart’ technology can decide whether what they are being offered is indeed ‘smart’ or just an expected level of technology.
After much hard work, Wilo believes it has identified what a true ‘smart’ pump should be; what it should offer and what it needs to do to transform the way installers work, day to day. Put simply, we think the world’s first true smart-pump should feature tomorrow’s innovations, making life easier today.
We understand a ‘smart-pump’ to be a new category of pump, which goes far beyond its predecessors. Only the combination of the latest sensor technology and innovative control functions – for example Dynamic Adapt Plus and Multi-Flow Adaptation – bi-directional connectivity using Bluetooth, integrated analogue inputs, binary inputs and outputs, an advanced interface, software updates and excellent usability, thanks to the setup guide, the preview principle for predictive navigation and additional tried and tested technology – that’s what makes a pump, a smart-pump.
Ask any installer what they want from a pump and easy installation will be their resounding reply. As with all components of a heating system, they want it to save time, do the job and be almost instinctive in its ability to be set up and ready to operate. New standards of system efficiency and user-friendliness would be nice. Taking the best of current technology and adding to it – perhaps increasing its levels of connectivity to make it even more flexible when it comes to integration in a wide number of potential applications. Analogue and digital interfaces would be impressive – these are optional features on some pumps, but ‘available as standard’ sounds like an impressive upgrade. And of course, the latest communication interfaces – Bluetooth – that would enable it to be directly connected to mobile devices and the addition of a means to offer connectivity across a range of products, for example to allow control of multiple pumps. That would be an excellent addition.
Additional CIF modules offering seamless integration into the world of bus systems would be impressive and the ability to operate and control the pump via a custom developed app that would read out data and make it available for system optimisation purposes – now that would be helpful.
In an ideal world, an application-guide configuration of the setup guide could offer intuitive handling and outstanding userfriendliness.
It could also offer the highest system efficiency on the market, as a result of the optimised and innovative energy efficiency functions – such as ‘Multi-Flow Adaptation’ and ‘No-Flow Stop’ along with an outstanding EEI – perhaps ≤ 0.17.
Multi-Flow Adaptation – a new energy saving function enabling the feeder pump to adjust its output to the precise demand of the connected consumption circuit pumps sounds like a decent addition. Additional elaborate control functions would be very user-friendly and enable exceptionally energy-efficient operation. The ability to automatically adapt its output to the varying system requirements via ‘Dynamic Adapt Plus’ without setting a target value would also be useful. How about a new terminal compartment with a clearer layout offering more space that no longer has to be opened to carry out the basic installation procedure? A heat quantity metering function would be another benefit allowing it to switch between heating and cooling mode to enable the separate metering of cooling quantities.
New control modes that ensure flexible and perfect adaptation for all applications – setting a constant target temperature or constant differential temperature, would make the operation of the pump and the overall system even more efficient. The target temperature control of the circulator would also assist with the prevention of legionella infestations in the warm water pipes.
That seems like a comprehensive list of requests to be part and parcel of a truly ‘smart’ pump. Well, this is now a reality with the launch of the new Wilo Stratos-MAXO, in April.
The new Green-Button-Technology is the successor to our red button and combines proven handling with new and optimised functions. It was important for us to make the installation of the pump even simpler.
“Wilo Net” offers a new standard interface for connectivity among Wilo products, making this pump one of the best-connected pumps on today’s market.
This is the template for pumps of the future. I’m not saying every pump will eventually aspire to its new, highly advanced ‘smart’ features and performance, but don’t be surprised if many do.
Installer Glen Wakeling gives his view:
Glen Wakeling from HeatSpec – a Leicester based firm of heating contractors specialising in domestic and light commercial heating – was instrumental in Wilo’s pre-launch testing programme.
Glen has made a name for himself in the industry for identifying equipment that provides the exact requirements of his customers. Glen will call out equipment that stands in his way of offering effective, efficient solutions. He prides himself in his system design as well as the installation of the equipment.
We asked him to report back on the use of the new pump. Did it meet his expectations of a ‘smart pump’?
“It’s opened my eyes to what is possible,” he admits. “I installed my first Wilo Stratos-MAXO in a seven-bedroom, three-bathroom property in the Leicestershire countryside. The new pump serves a heating system that includes a Viessman Vitodens 200 system boiler, a Viessmann Vitocell domestic hot water cylinder, a Spirotech SpiroCross low loss header unit, a Flamco expansion vessel attached to the Flamco Flexconsole Plus with an integrated Flexvent safety pressure valve.
“Once you get over the initial size of the pump – it’s a beast – installation is simple and straightforward.
Once it’s in and connected it’s simple to initially set it up using its ability to automatically adapt its output to the varying system requirements via the ‘Dynamic Adapt Plus’ setting without setting a target value. That in itself improves efficiency by 20% over and above the best alternative pump I’ve used.
“And by utilising the settings available on the huge screen on the pump you can refine its performance even more. For jobs where this is the right pump for the job, it’s second to none.”
