Hydraulic pump optimized for electrified off-highway vehicles

By mgannon | April 21, 2025

Parker Hannifin has launched the T8MINI, a new series of medium-duty, fixed-displacement vane pumps designed to support the growing shift toward electrified equipment in mobile and industrial sectors.

Parker T8MINI Vane pump

The T8MINI is designed for applications where electrification is accelerating, such as construction, mining, marine and offshore, agriculture, oil and gas, and transportation, particularly in mini and mid-sized machinery.

While not developed for light-duty automotive EVs, the pump is specifically engineered for integration into low-carbon electric systems used in utility and industrial mobility platforms.

Based on established Denison vane technology, the T8MINI builds on the T7 series by introducing performance enhancements that support high-speed operation, reduced power consumption, and low noise output — all within a compact footprint. When paired with a synchronous brushless electric motor, the pump enables improved energy efficiency, longer operational time, and reduced total system noise.

The T8MINI supports displacement variants of 6, 8, 10, and 12 cc/rev, operating at speeds up to 5,000 rpm, pressure up to 330 bar, and flow rates up to 60 lpm. It is designed to perform in demanding environmental conditions, with cold-start capability at 5000 cSt and high-temperature tolerance down to 10 cSt.

Additional updates include a ten-vane configuration with double-lip vane technology, lightweight construction (up to 40% lighter than the T7A series), and improved self-priming speeds by more than 38%. Overall pump efficiency has increased by 14% over the T7A. A SAE A two-bolt J744 mounting flange, splined shaft, and multiple threaded port options are standard.

The compact size and compatibility with smaller torque motors make the T8MINI well-suited to electrified platforms undergoing system downsizing for efficiency and emissions reduction. It is positioned to support the development of electric-powered systems where quiet operation, footprint reduction, and long service life are critical design priorities.
