Reciprocating pump have low efficiency and shorter life span.

Low cost & high efficiency.

The reciprocating pump has high efficiency,
Also, k/a positive displacement pump has high head low discharge.

D) hydraulic ram - low cost, high efficiency, low discharge.

Hydraulic ram pump = no energy, high-level point to low-level point water discharge.

Air left pump = low suction head, moderate discharge and enter solids, pump injection bottom compressed air producing with discharge involved.

High head low discharge - reciprocating pump.

High discharge low head - centrifugal pump.

Reciprocating pump is a positive displacement pump. The given pump is single acting single cylinder pump with air vessel. It can be used for less discharge at higher heads. Priming is not required because it is a positive displacement pump.

Reciprocating pumps are used in pumping water in hilly areas. Reciprocating pumps has lower efficiency compared to centrifugal pumps.
