The use of fluid (hydraulic pump and motor) power transmission systems to drive water pumps is a relatively recent development. The first units of any size were first marketed in the late 1960s and early 1970s and were utilized primarily for construction dewatering purposes because they can be driven by diesel engines or electric motors located well away from construction site cave-ins without the inconveniences of priming and suction hoses and with no limitation on suction lift or capacity (Figure 1).
