A study was undertaken to design and construct a low-lift double pedal, double cylinder operated pump for use in small irrigation project areas. The double pedal pump was operated by one adult man power. The pump discharge rate, speed, maximum lift, discharge length, suction head and efficiency were determined. The average discharges of the pump ranged from 10.1 to 1.6 litres per minute were noted against heads of 0.35 to 2.1m. It was observed that the discharge rate depends on effort applied by operator and suction head. Efficiency of the pump was 57 percent against a head of 0.35 m. The double pedal pump can be constructed using local materials and skill. It would be suitable to irrigate small plots like vegetables and seed beds with less physical effort.
