About
Henry Guenther is president and owner of Hartmann Controls, the Hartland manufacturer of industrial hydraulic pumps, servo Rol-vane motors, and related fluid-system components.
Company materials say Hartmann has produced hydraulic and fluid systems for more than 60 years from its Hartland plant northwest of Chicago, serving railroad, construction, mining, energy, oil and gas, wood processing, and other industrial and mobile markets—including fire-resistant and bio-engineered fluids and DEF delivery systems.
Hartmann states it machines critical components in-house, functionally tests every fluid-control product before shipment, and holds ISO 9001:2015 certification, citing supplier recognition from customers including GE Energy and Caterpillar. LinkedIn lists Guenther as president since 2003 with owner responsibilities for strategic planning and returns for the ownership group.
That Hartland manufacturing base keeps Guenther's industrial-OEM leadership on the village page, even as the company ships pumps and motors into national rail, energy, and mobile equipment markets from its Lake Country plant.
