A non-pulsation twin pump is provided to reduce vibration of a pipe or a structure, vibration and noises of the pump remarkably by transferring and compressing a fluid without pulsation. A non-pulsation twin pump includes a body(10), a pair of pump room, an opening unit, and a casing(20). The pump rooms are installed at one inside of the body. The opening unit connects to the pump room. The casing includes the opening unit and an inlet hole and an outlet hole formed at both sides of the opening unit. A piston is installed in the casing and composed of a first head unit(31), a second head unit(32), and a partition(33) connecting the first head unit and the second head unit. A gear box(11) is formed at other inside of body, other side of the cylinder with a partitioning wall. The gear box includes an operating crank shaft(41), a passivity crank shaft(42), a first operating eccentric gear(43), a second operating eccentric gear(44). The first head unit of the piston is installed at the operating crank shaft. The second head unit is installed at the passivity crank shaft. The first and second operating eccentric gear connects the operating and passivity crank shaft. A pair of parallel eccentric gear(45,46) are installed next to the operating eccentric gear installed at the operating crank shaft. Other eccentric gear is connected to a motor shaft(40).
