Hydraulic ram pumps are equipped with air vessel to reduce the pulsation of the pumping water flow and the acceleration head loss. In their operation, the amount of air available in the air vessel will be decreased continuously flowing out with delivery water. In order to replace the air volume in the air vessel, the hydraulic ram pump is equipped with a snifter-valve. However, in its implementation, this valve is a hole or orifice with a diameter of 2 mm at a distance of about 2 cm below the delivery valve on the body of the hydraulic ram pump. On the other hand, this will reduce the water hammer pressure that occurs, furthermore, it reduces the performance of the hydraulic ram pump. Based on its working principle, a snifter-valve is an automatic anti-vacuum valve or a non-return valve or check valve. Therefore, the work has been carried out to investigate and analyze the performance of a hydraulic ram pump without a hole or any snifter-valve, with a hole of 1 mm diameter, and equipped with a check-valve of 1 mm orifice diameter. The results showed that the snifter-valve with check-valve of 1 mm orifice diameter gives the best hydraulic ram pump performance for the hydraulic ram pump model that has been investigated.
