   Other solutions have focused on innovative pump systems, including hand-pumps, Water for People's "Play Pumps", [17] and Pump Aid's "Elephant Pumps". [18] All three designs are built to aid communities in drawing clean water from wells. The hand pump is the most basic and simple to repair, with replacement parts easily found. [19]

   Also, the dimensions of the separating chamber are relatively large. For these reasons this solution is only adopted for small pumps, e.g. garden pumps. More frequently used types of self-priming pumps are side-channel and water-ring pumps. Another type of self-priming pump is a centrifugal pump with two casing chambers and an open impeller.
