A new type of pump with a water-type stirling engine using the water-hammer principle is developed, and its characteristics are studied experimentally. The output oscillation of the engine is utilized for pumping water. Another type of pump with an ordinary water-piston engine, the so-called liquid piston stirling engine, is also tested to compare with the performance of the newly designed pump. The characteristic curves of the pumps indicate that the new pump has a relatively higher delivery pressure at the same low discharge flow than the other type. Conversely, the new pump has a relatively lower delivery pressure at the same high discharge flow. Moreover, the delivery pressure in the new pump is directly related to the pressure in the water hammer. The test results indicate the potential of the new design for the improvement of the pumping head.
