Centrifugal vs reciprocating pump
List out the differences between Centrifugal vs reciprocating pump.
| Centrifugal pump | Reciprocating pump |
| It is one of the rotary pumps which used kinetic energy of impeller. | It is a positive displacement type pump which is forced by piston. |
| It continuously discharges the fluid. | It does not discharge the fluid continuously. |
| In centrifugal pump the flow rate decreases which increasing the pressure. | The pressure does not affect flow rate in reciprocating pumps. |
| It is used for pumping high viscous fluid. | It is used for pump low viscous fluid. |
| In this pumps discharge is inversely promotional to the viscosity of fluid. | In reciprocating pump viscosity of fluid does not affect the discharge rate. |
| Efficiency of these pumps are low compare to reciprocating pump. | Efficiency is high. |
| Centrifugal pump have problem of priming. | It does not have any problem of priming. |
| It uses impellers to transfer energy to fluid. | It uses piston cylinder device to transfer energy to fluid. |
| They are lighter than reciprocating pumps. | These are heavier compare to centrifugal pump. |
| It gives higher discharge at low heads. | These gives higher heads at low discharge. |
| It is less costly. | These are costly. |
| These pumps required less maintenance. | These required higher maintenance. |
| Centrifugal pumps are easy to install. These required less floor space. | These pumps are difficult to install. These required more floor area. |
| It is mostly used for domestic purpose and where higher discharge at low head required. | These are mostly used in industries and high viscous fluid pumped at a high head. |
