* depending on flow and viscosity

Due to its closed loop operation, the Schumacher hydraulic power unit (with Bucher hydraulics valve) supplies consistent operation regardless of load and temperature. A stepless, linear travel profile is accomplished by utilizing a proportional solenoid. The solenoid voltage is adjusted with the aid of a flow sensor to guarantee a consistent ride with minimal leveling. Consequently, motor run times are reduced by as much as 30%, saving power and creating an environmentally friendly product. Bucher valves also reduce the need for heating and cooling systems, which are required by most other hydraulic systems. Schumacher power units utilizing a Bucher hydraulics electronic valve offer optimum assurance that elevators are

capable of handling high-traffic applications.
