Hydraulic Elevator Systems
The vast majority of today’s elevators are one of two basic designs, traction or hydraulic. Hydraulic types of systems are typically less expensive and are found in buildings with a maximum of six or seven floors. These systems typically feature a rotary three-screw pump because of the pump's quiet, smooth and reliable operation.
