Schäffer Multi High Flow revolutionises the hydraulic power of compact loaders and wheel loaders by delivering a disproportionately high output for attachments while greatly enhancing operating comfort. It enables operation at lower engine speeds and ensures that working movements, like lifting and lowering, can be executed and hydraulic auxiliary drives operated without noticeably impacting the attachment’s main function.
Multi High Flow allows, for example, full-load operation of a straw spreader while at the same time hydraulically adjusting the discharge chute and operating the boom, without affecting the discharge width and height. This guarantees greater comfort for farmers and speeds up work. At the heart of the innovation is the demand-driven, pressure-independent distribution of the hydraulic flow rate. The attachment is always prioritised, thereby ensuring no noticeable drop in performance, even when additional functions like the third control circuit or the boom are operated simultaneously. This is achieved by interconnecting two flow rates and utilising a specially designed valve block.
High hydraulic power for compact loaders
Thanks to Multi High Flow, hydraulically demanding attachments can also be operated on relatively small loaders. As a result, more compact machines can be used, which ultimately leads to reduced investment and operating costs. For example, the 50 hp compact loader 3650 provides a hydraulic power of 81 l/min. Furthermore, Multi High Flow is available for Schäffer compact loader 4670 and for wheel loaders 4670 Z-2 and 5680 Z, in this case with up to 115 l/min.
Comfort and efficiency for farmers
Schäffer Multi High Flow offers much greater comfort for farmers. Various functions on both the loader and the attachment can operate concurrently without noticeably diminishing the hydraulic supply to the attachment. Yet another advantage is being able to operate the loader at reduced engine speed, which obviously helps save fuel and lowers operating costs. Since the system provides a high flow rate, the loader does not have to be operated at full load. Operating at lower engine speeds results in significantly quieter performance and less pollutant emissions, which is especially beneficial when working in stables and around animals. To achieve the same level of output, older loader models required much larger hydraulic pumps that were not demand driven and, therefore, worked much less efficiently.
Patented valve technology
Friedhelm Brede, Head of Development at Schäffer, sums up the advantages of the new technology: “Schäffer Multi High Flow signifies a major advancement in hydraulic technology that offers both efficiency and comfort for daily operations. This innovation allows farmers to work more efficiently, cost effectively and sustainably. We are happy and proud to have received a patent for the system from both the European Patent Office and the German Patent and Trademark Office.”
Schäffer will showcase its innovative hydraulic system, new loaders and numerous other machines at EuroTier 2024, in Hall 27 at Stand A15.
