Reciprocating pumps are used
to transport both clean and abrasive fluids
. These pumps are more efficient and robust than their centrifugal or rotary counterparts, making reciprocating pumps the ideal choice for the oil and gas industry.
What is the purpose of reciprocating pump?
Reciprocating pumps are used
where a precise amount of fluid is required to be delivered
, also where the delivery pressure required is higher than can be achieved with other types. The fluid is moved by the means of a piston that travels in a cylinder.
How does a reciprocating pump work?
The reciprocating pump works
on the principle of positive displacement
. A reciprocating piston pump consists of a piston that moves back and forth in a cylinder. The piston is connected with a crankshaft with the help of a connecting rod. This piston moves as the connecting rod move due to the motion of the crankshaft.
When reciprocating and centrifugal pump is used?
| S. No. Centrifugal pump | 4. It is used for pumping high viscous fluid. | 5. In this pumps discharge is inversely promotional to the viscosity of fluid. | 6. Efficiency of these pumps are low compare to reciprocating pump. | 7. Centrifugal pump have problem of priming. |

What is the function of reciprocating?
Reciprocating compressors are positive-displacement machines that compress and move gases by using a combination of rotational and linear (reciprocating) motion. Their basic function is
to raise the pressure level of the gas being compressed
.
Which is an example of reciprocating pump?
A reciprocating pump is a class of positive-displacement pumps that includes the
piston pump
, plunger pump, and diaphragm pump.
What is difference between centrifugal pump and reciprocating pump?
The main differences between Centrifugal Pump and Reciprocating Pump are the
Centrifugal pump works low medium pressure head and Reciprocating Pump works high medium pressure head
.
What is the working principle of Eductors?
Working Principle of Eductor on Ships
Eductor works on Bernoulli’s principle. It
states that an increase in the speed of a fluid occurs simultaneously with a reduction in pressure
. Refer to the simplified Bernoulli’s equation below for an in compressible flow.
Which pump is more efficient?
Where different pump designs could be used, the
centrifugal pump
is generally the most economical followed by rotary and reciprocating pumps. Although, positive displacement pumps are generally more efficient than centrifugal pumps, the benefit of higher efficiency tends to be offset by increased maintenance costs.
Do reciprocating pumps Cavitate?
Two basic types of cavitation exist in reciprocating pumps: Suction cavitation can result
from obstructed, clogged
, or otherwise dysfunctional inlet pipes. When the inlet pipe’s optimal flow is hampered, vapor cavities form near the retracting plunger.
What are the advantages of centrifugal pump?
- Corrosion Resistance. Finish Thompson’s centrifugal chemical pumps are manufactured using corrosion-resistant materials. …
- Energy Efficiency. …
- Smooth Flow. …
- Proven Reliability. …
- Low Maintenance. …
- Size Versatility. …
- Application Versatility.
What are the advantages and disadvantages of centrifugal pump over reciprocating pump?
Centrifugal pumps
require less floor space than reciprocating pumps of equal capacity
because of the simpler design. Also, the capacity of the centrifugal pump can be increased more easily by enlarging the inlet and outlet diameters and increasing the impeller speed.
What is the purpose of centrifugal pump?
Centrifugal pumps are used
to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow
. The rotational energy typically comes from an engine or electric motor. They are a sub-class of dynamic axisymmetric work-absorbing turbomachinery.
How does a reciprocating engine start?
The
inertia starters use the transfer of energy
to start the reciprocating engine. As the motion of cranking—by hand— or rotation—by an electric motor— is initiated, the energy is transferred linearly or rotationally. … When the starter is engaged, the energy is transferred to the flywheel, and then to the engine.
What is another name for reciprocating engines?
A reciprocating engine, also known as
a piston engine
, is one of two types of combustion engines, which work by combusting fuel to create energy. The other type is an earlier form called a rotary engine, and while still in use today, reciprocating engines are more common in many industries.
What are the major components of reciprocating engine?
The basic major components of a reciprocating engine are the
crankcase, cylinders, pistons, connecting rods, valves, valve-operating mechanism, and crankshaft
.
