Single and Double Acting Reciprocating Pump

Question

Write differences between single acting reciprocating pump and double acting reciprocating pump.

Answer 1

Single Acting Reciprocating Pump

1. Fluid is pumped during delivery stroke of the piston.
2. Volume of fluid pumped is low. 
3. Idle stroke is present.
4. Less efficient in terms of volume of flow.
5. Weight is less.
6. Less initial cost. 
7. Maintenance cost is less.

Double Acting Reciprocating Pump

1. Fluid is delivered during forward and return stroke of the piston.
2. High volume of fluid can be pumped.
3. No idle stroke.
4. Highly efficient interms of volume of flow.
5. Weight is more.
6. High initial cost.
7. High maintenance cost.
