Reciprocating Pump: A positive displacement pump which utilizes a plunger or piston to change a cavity's volume, and produce a pressure differential. A plunger pump operates using the reciprocating motion of plungers or pistons. Depending on the design of the pump, the use of a single or multiple plungers may be used.

What is a reciprocating pump used for?
Reciprocating Pumps are positive displacement machines typically used for low-flow, high-pressure operations. ANSI and the Hydraulic Institute categorize reciprocating pumps by four types. Both pistons and diaphragms are used to provide pumping action while valves regulate flow into and out of the pump body

How does a reciprocating pump work?
The working of reciprocating pump is as follows: When the power source is connected to crank, the crank will start rotating and connecting rod also displaced along with crank. ... When the crank moves inwards or towards the cylinder, the piston will move towards its left and compresses the liquid in the cylinder.

Which type of pump is most efficient?
In general, a reciprocating pump is more efficient than a centrifugal pump. Reciprocating machines are generally applied on low-flow/high-head service. Centrifugal pumps can have efficiencies as low as 40 percent on low-flow/high-head service.

What is the major drawback of reciprocating pump?
Disadvantages of Reciprocating Pump:

The flow is very low and cannot be used for high flow operation. They are more heavy and bulky in shape. The initial cost is very high in this pump. More parts mean higher initial costs.
