<p>Disclosed herein is a rotary positive displacement pump for fluid compressors, which is small in size and is suitable for a large quantity of flow and a high head, and which shows excellent performance upon low-speed rotation and high-speed rotation. The pump is suitable for a large quantity of flow and a high head, is capable of moving a large quantity of fluid to a high position, and is operated by varying the volume, so that the pump is operated at high efficiency, thus preventing efficiency from being reduced upon low-speed rotation or high-speed rotation. The pump forms a completely balanced rotating mechanism, thus preventing vibrations from occurring due to unbalanced rotation of components even when rotating at high speed. Further, the pump solves the drawbacks occurring in different kinds of pumps upon both low-speed rotation and high-speed rotation, thus being used for various purposes and showing high performance.</p> |
