Common questions

Which pump is better reciprocating pump or centrifugal pump?

Which pump is better reciprocating pump or centrifugal pump?

Reciprocating pumps can be more efficient than centrifugal pumps, if they are used in the correct application. Reciprocating machines are generally applied on low-flow and high-head service. Centrifugal pumps can have efficiencies as low as 20 percent on low-flow and high-head service.

Is centrifugal pump a constant discharge pump?

The efficient operation of a centrifugal pump relies on the constant, high speed rotation of its impeller. Additionally, if the feed pressure is variable, a centrifugal pump produces a variable flow; a positive displacement pump is insensitive to changing pressures and will provide a constant output.

What type of pump provides constant pressure?

positive displacement pump
What is a positive displacement pump? A positive displacement pump provides a constant flow at fixed speed, regardless of changes in pressure. The pump makes the fluid move by trapping a fixed amount and forcing the volume into the discharge pipe.

Which pump will you prefer for high discharge flow?

Centrifugal pumps
Centrifugal pumps are the most common pump type for the transfer of low viscosity fluids in high flow rate, low pressure installations, which makes them ideal for applications that require the pump to deal with large volumes.

When reciprocating and centrifugal pump is used?

Difference between Centrifugal Pump and Reciprocating Pump:

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.

Which type of pump is most 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.

What is the difference between centrifugal pump and submersible pump?

A submersible pump is installed underwater whereas a centrifugal pump is installed on the ground. Therefore, submersible pumps are used for groundwater extraction through deep wells and centrifugal pumps are ideal for water supply and drainage applications in urban areas or for industrial purposes.

What is the discharge of centrifugal pump?

Explanation: Discharge of a centrifugal pump is directly proportional to (Diameter)^2 of its impeller. Head of a centrifugal pump is directly proportional to (Diameter)^2 of its impeller. Power Developed of a centrifugal pump is directly proportional to (Diameter)^4 of its impeller.

What is the difference between centrifugal 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 centrifugal pump and reciprocating pump?

The centrifugal pump is also called a rotary pump as it uses the kinetic energy of an impeller to force the fluid and increase the kinetic energy. On the other hand, a reciprocating pump which is also called a positive displacement pump works with a piston cylinder.

Where is reciprocating pump used?

Incorporating reciprocating pumps results in repeatable and precise mechanical operations. Industries that commonly use reciprocating pumps include: Oil and gas: Oil and gas industry applications include disposal, offshore oil, production, injection, feed, charge, steam generators, mainline, and field gathering.

READ:   How do I know if my Android has a keylogger?

What should I do if my centrifugal pump has no flow?

Do not let a centrifugal pump operate for long periods of time at zero flow. In residential systems, the pressure switch shuts the pump down when the pressure is high which means there is low or no flow. 3. Use pressure gauges

What is centrifugal pump?

Centrifugal pump which is also known as rotary pump used kinetic energy of impeller to force the fluid and increase its kinetic energy. This kinetic energy suddenly converts into pressure energy which move fluid upward.

What are the differences between reciprocating pumps and rotary pumps?

There are some modified reciprocating pumps are available which gives continuous discharge. There are many other differences which are described as follow. 1. It is one of the rotary pumps which used kinetic energy of impeller.

What is the relationship between flow and pressure in a pump?

1. Flow and pressure relationship of a pump. When the flow increases, the discharge pressure of the pump decreases, and when the flow decreases the discharge pressure increases (ref. tutorial2.htm). 2. Do not let a pump run at zero flow. Do not let a centrifugal pump operate for long periods of time at zero flow.
