Evaluates volumetric efficiency in hydraulic ram pumps, suggesting optimal configurations for better performance.

The aim is to enhance the volumetric efficiency of hydraulic ram pumps through component configuration testing.
Conducted trials at varying delivery heads of 2.5 m and 5.0 m.
Tested different sizes of delivery and waste valves to find optimal configurations.
Performed statistical analysis to link efficiency with operational times and system pressure.
Achieved maximum volumetric efficiency of 14.14% at 2.5 m delivery head.
At 5.0 m head, the best performance reached 7.82% with larger valves.
Found that higher efficiency correlates with shorter operational times (R = -0.67) and increased system pressure (R = 0.55).

Ghomi et al. (2026) studied this question.
