Thought of the day: Electric Hydraulic Steering Pump – Steering pumps have gradually moved from pure hydraulic to electric-over-hydraulic over the last several decades. In fact, on most passenger cars and trucks, the steering is now purely electro-mechanical, meaning there is no hydraulics at all. But when it comes to medium- and heavy-duty trucks and off-highway vehicles, hydraulic steering is here for quite some time. But we can help make these systems simpler, more efficient and more powerful with our electric hydraulic steering pump known as the Hydrapulse EHSU.

Terminology: This technology can be called several different things but some of the common terms are: electric hydraulic steering pump, electro-hydraulic steering pump, EHS, EHSP, electro-hydraulic steering pump, hydraulic steering assist pump, e-steering pump, steer-by-wire pump and many more.
