What is the working principle of reciprocating pumps?
Reciprocating pumps work based on the principle of reciprocating motion, which involves back-and-forth movement of a piston or a plunger within a cylinder. These pumps are positive displacement pumps, meaning they displace a fixed amount of fluid with each stroke or cycle.
Here is a general overview of the working principle of reciprocating pumps:
Cylinder and Piston/Plunger:
The pump consists of a cylinder, which is a closed chamber, and a piston or a plunger that fits tightly within the cylinder.
Inlet and Outlet Valves:
The cylinder has inlet and outlet valves. The inlet valve allows the fluid to enter the cylinder from the source, while the outlet valve permits the fluid to exit the cylinder.
During the suction stroke, the piston or plunger moves away from the outlet valve, creating a low-pressure area within the cylinder. This low pressure causes the inlet valve to open, allowing the fluid to enter the cylinder.
In the discharge stroke, the piston or plunger moves towards the outlet valve, causing the volume within the cylinder to decrease. As a result, the pressure within the cylinder increases, causing the outlet valve to open and allowing the fluid to be discharged from the pump.
Reciprocating pumps typically have check valves at the inlet and outlet. These valves ensure that fluid flows in the desired direction by allowing flow in one direction while preventing backflow.
The reciprocating motion of the piston or plunger is usually generated by a crankshaft mechanism, an electric motor, or other means of converting rotary motion into reciprocating motion.
The suction and discharge strokes alternate in a continuous cycle, allowing the pump to continuously draw in and discharge fluid.
How do you know which pump is the centrifugal pump and each reciprocating pump?
- With the help of the pump casing design.
- In a reciprocating pump mostly, dampener is used to give the uniform flow.

What do you mean by the stroke in the pump?
How do you identify which one is single acting and which one is a double acting pump?
Why use the double acting reciprocating pump?
Which pump is used for dodging the chemical in the tank?
What is the valve condition during the operation of the reciprocating pump?

Why priming is not required in reciprocating pumps.
What is the SOP of reciprocating pump single acting?
- Check the nitrogen pressure in the damper.
- Check the lubrication of all parts.
- All types of lubrication have been given in running conditions after that motor starts.
- The pump operation will start during the start of the motor.
- Before the start pump all suction and discharge valves should be in open conditions.
