The new T8MINI medium-duty, fixed-displacement vane pump series is designed and optimised to meet the growing demand for more efficient, low-carbon electrical equipment. It is especially suitable for mobile mini and mid-size machinery applications in construction, mining, marine & offshore, agriculture, oil & gas, and transportation.
The T8MINI was developed based on the Denison vane technology, retains the best features of the previous T7 vane pump series, and adds new features to offer a quiet and efficient pump that is optimised for electric systems. Combined with a synchronous brushless electric motor, the T8MINI is said to improve machine performance to deliver high efficiency, high machine operational time, low noise levels and low total cost of ownership - all in a compact footprint.
The T8MINI owes its high overall efficiency to a low hydro-mechanical efficiency with low acceptable values of volumetric efficiency. In high-speed applications, the T8MINI and electric motor combination results in a reduction in total power consumption and extended periods of operation.
According to Parker, low noise levels are guaranteed thanks to Denison silent vane pump technology. The T8MINI, therefore reduces environmental impacts, particularly in urban areas, and protects workers’ wellbeing. The ePump compact and affordable solution is easily obtained thanks to small displacements range provided by the T8MINI that require small torque matching with downsized small electric motor.
The new T8MINI series is available in four displacement variants - 6, 8, 10, and 12 cc/rev - with speeds up to 5000 rpm, pressure up to 330 bar, and output flow up to 60 l/min. These vane pumps can also operate in a wide range of harsh environmental conditions, including cold starts at 5000 cSt and very hot conditions up to 10 cSt.
The T8MINI cartridge design features double-lip vane technology in a 10-vane configuration. New materials and coatings add to the improvements in reliability, compared to the T7 series. The T8MINI is up to 40% lighter than T7A series, and up to 20% more compact. The self-priming speed is improved by more than 38% and the overall efficiency is now 14% better than the T7A series.
“The T8MINI offers the best combination of high performance, low noise, compact size and cost when choosing the right ePump for your variable speed application,” stated Dr-Ing Emanuele Gnesi, project manager at Parker’s pump & motor division Europe. “Being innovative and one step ahead of the competition means looking differently at new electrification challenges, being daring and breaking with tradition. Delivering on our ambition to optimize the performance of current and future electrically-powered machines means new engineering breakthroughs are necessary. This was our inspiration in developing the T8MINI by focusing on reducing power consumption, lowering emissions, and improving longevity to support customers during the transition.”
