“…New attention was given to this old technology at the end of the century [11][12][13][14], and even more recently, due to the increased focus on sustainability and renewable energy sources [15], different studies have focused on the modelling [16,17], design [18] and performance of the ram pump [19][20][21][22][23][24]. Specifically, the authors of [21,22] studied the effects of the waste valve on the performance of the hydram. Both experimental and numerical approaches were used to investigate this topic [25][26][27][28] for different specific purposes [29][30][31][32].…”

“…Suarda et al [21,22] carried out experiments on a hydram varying all geometric parameters of the waste valve; furthermore, they proposed procedures for estimation of the optimal diameter and its stroke and the optimal mass of the waste valve that can deliver the best hydraulic ram performance. Sucipta et al [23] performed experiments in order to find the best geometrical configuration of the snifter valve in order not to reduce the performance of the hydraulic ram pump.…”

The hydraulic ram pump or hydram is a machine capable of lifting water to a hydraulic head higher than the level of the supply source. It is a sustainable and self-sufficient device: the working principle is based on the rise of abrupt pressure variations occurring in the feeding pipeline when the liquid inside it undergoes a locally sharp change in velocity as a consequence of the sudden closure of the waste valve. Invented in 1772, the pump has been improved over the decades. Due to its simplicity, low cost and reliability, it has been widely used worldwide to provide adequate domestic water supplies, especially before the spreading of electricity and internal combustion engines. In recent years, the new attention placed on sustainability and energy transition from fossil fuels to renewable energy devices has brought a growing interest to this basic machine, essentially forgotten and abandoned in the last century; it seems promising especially in developing countries. The hydram is, in fact, a very simple machine, with only two moving parts, the waste and delivery valves. The efficiency of the hydraulic ram pump is mainly influenced by the characteristics of the waste valve. However, sufficient data are not available for the design of the hydram and the waste valve. In this work, the behaviour of the waste valve of a hydram was simulated by means of Computational Fluid Dynamics (CFD). Velocity and pressure values were analysed for different scenarios with different closing times of the valve. The data obtained from the developed numerical model were compared, in order to verify the validity of the simulations, with those collected during the operation of the hydram placed at the Laboratory of Environmental and Marine Hydraulics (LIDAM) of the University of Salerno, Italy. The numerical model thus obtained can, therefore, be used to identify the ideal configuration of the valve in order to ensure the best performance of the hydram.

“…Pompa Hidram yang digunakan dalam kegiatan pengabdian masyarakat ini adalah pompa air tanpa listrik dan tanpa bahan bakar. Pompa Hidram tanpa listrik dan bahan bakar adalah pompa hidram yang bekerja menggunakan hentakan hidrolik air (Suarda, Sucipta, & Dwijana, 2019). Pada prinsipnya, pompa hidram menggunakan energi kinetik dari air yang mengalir lalu aliran air tersebut secara teratur melewati sebuah katup (Jafri & Sanusi, 2019).…”

The combined pump and hydraulic ram pump (HRP) was presented to evaluate the technical feasibility for increasing pump head. This method was used to demonstrate a possible low-cost alternative solution to supply water in remote areas. It illustrated the case where energy in rivers was not enough to drive HRP and a pump alone could not lift water to the required head. The HRP was connected in series with the pump. The experiment on the combined system operation was investigated. The system was working only at a certain range of flow rates for a power supply by the pump. Therefore, HRP was adjusted to pump water in the range that the waste valve was functioning. The combined system can operate at a low flow rate with a high head without extra energy and no overloading. It reveals that the more discharge head is required, the less flow can be lifted which results in a high number of valve beats per minute of the waste valve. Experimental determination of the optimal values for these parameters will make it possible to provide for a feasible design of HRP in the given pump. The optimal HRP will make it possible to ensure the required performance (delivery, head, efficiency) of the combined system.
