The increased durability and better response to load changes offered by the hydraulic motor lower the expected replacement cost for the pump system over the long run. Yet electric motors can still cost more if there’s an emergency, such as an overload that causes a stall, as this type of event will destroy an electric model and necessitate full replacement. On the other hand, hydraulic generators are powered by liquid fuel, however, they need routine cleaning, filter replacements, tune-ups, fluid changes, and more. As long as an electric motor is properly sized and operated under an approved load level, it can run for years with little interruption or maintenance. However, the actual electrical power system tends to require additional pieces of equipment, the entire pump power system may cost more when it is built around an electric motor.Įlectric motors and hydraulic power units also require greater maintenance and thus higher costs. Electric motors, which are widely available for standard use, such as slurry pumping, are available at a reduced cost. Electric motors and diesel powered hydraulic power units vary in both upfront and ongoing operation costs.
