Am încercat sa redirectionez spre link-ul cu aceste informații, dar nu reușesc cu rețeaua de aici.
Se pare ca sunt câteva noutăți la modelele actuale .
Pe "Wholelattelove", dar nu numai acolo, este descris "The New Brewtus IV rotary pump".

"Commercial Rotary Pump
The commercial, 120-watt rotary pump is designed to work with a plumbed water line. In most cases, you will not need a pressure reducer as it can run on incoming water pressure between 5 and 65psig. You can also drop the stainless steel water intake line into a large water jug, if you prefer not to plumb the Expobar Brewtus IV-R; but please be careful not to let the pump run without water, as this can cause damage to the machine.
Additionally, you can run a drain line from the drip tray to eliminate the need to empty it by hand. To set the drip tray up to work with a drain line, a hole will have to be drilled into the drain pan. We are happy to modify the drip tray here, at Whole Latte Love, or you can do it at home. If you set the machine up with a water line, we recommend that you also hook it up to a drain line.

Improved E-61 Brew Group and Portafilter
The Brewtus IV-R is outfitted with the renowned chrome-plated brass E-61 Brew Group, celebrated for its ability to offer unwavering temperature stability. It is backed by a state-of-the-art thermo siphon system that circulates hot water from the boiler to maintain group head temperature. New to the forth generation of the Expobar Brewtus machines is a concave pre-infusion chamber that allows hot water to be evenly distributed through coffee grounds for superior espresso extraction. Unlike conventional E-61 brew groups, this group head directs water through the brew group in a concentrated stream. Once the water hits the center of the shower screen, it floods back up into the pre-infusion chamber before being evenly dispersed through the coffee grounds for uniform saturation during the pre-infusion and brewing process. Accompanying the E-61 Brew Group is a professional chrome-plated brass 58mm portafilter as well as single and double-shot filter baskets."
