Abstract: The experiment conducted at Mahamaya College of Agricultural Engineering & Technology, Ambedkarnagar (U.P.).The pump tested for analysis performance is equipped with 2HP three phase induction electric motor with 1440rpm.The discharge was measured with stop watch having 1/100sec. least count. The pump was tested for three different speed of 242 rpm, 285 rpm and 344 rpm with five different pressure are 1.5 kg/ cm2, 5.7 kg/cm2,10.3kg/cm2, 15kg/cm2 and 24kg/cm .A pressure gauge having capacity 0-35kg/cm was used to record all pipe pressure used for this testing. The pulley with minimum diameter 6.25cm was fitted in motor shaft a V(twin) belt the electric connection was energized. The result based on the experimental observation revealed that the efficiency increased when pressure is increased. At speed 344 rpm the efficiency is observed 90% and at same speed the volumetric efficiency is 77%for lowest pressure 1.5kg/cm and volumetric efficiency is 95% for highest pressure 24kg/cm2.The pressure and average discharge indicate that as pressure increases the discharge increases and which almost linear.
