What Are The Advantages And Disadvantages Of Centrifugal Pump?

What are the advantages of reciprocating pump?

Advantages of Reciprocating PumpsHigh Pressure, Low Flow Applications: Reciprocating pumps are generally designed to pump in low flow, high head applications.

Proven, Common Technology: Reciprocating pumps are one of the oldest, most proven pump types.More items….

Which of the following is an example of reciprocating pump?

Types. Simple hand-operated reciprocating pump. The simplest example is the bicycle pump, which is used ubiquitously to inflate bicycle tires and various types of sporting balls. The name “bicycle pump” is not really the most correct term because it generates more compression than volume displacement.

Why relief valve is not used in centrifugal pump?

Because maximum pressure with the discharge closed is only moderately above working pressure, a relief valve is not necessary for a centrifugal pump.

What is pump and types?

Pumps can be classified by their method of displacement into positive-displacement pumps, impulse pumps, velocity pumps, gravity pumps, steam pumps and valveless pumps. There are three basic types of pumps: positive-displacement, centrifugal and axial-flow pumps.

What is use 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 reverse function of the centrifugal pump is a water turbine converting potential energy of water pressure into mechanical rotational energy.

What is the principle of centrifugal pump?

A Pump is generally used to induce flow or raise the pressure of a liquid. Centrifugal pumps are a category of Dynamic pumps. The working principle of centrifugal pumps involves imparting energy to the liquid by means of a centrifugal force developed by the rotation of an impeller that has several blades or vanes.

What is the difference between reciprocating pump and centrifugal pump?

The reciprocating pump provides a nearly constant flow rate over a wider range of pressure; the centrifugal pump gives uniform pressure over a range of flow, then it drops dramatically as the flow rate increases. On a reciprocating pump, fluid viscosity has little effect on the flow rate as the pressure increases.

What is difference between centrifugal pump and rotary pump?

Centrifugal pumps differ from rotary pumps in that they rely on kinetic energy rather than mechanical means to move liquid. … Liquid is forced out of the pump by the energy it obtains from the rotating impeller.

Why speed of reciprocating pump is lower than centrifugal pump?

A centrifugal pump increases the kinetic energy of a liquid because of centrifugal velocity from the rotation of the pump impeller. This kinetic energy is converted to pressure energy in the pump volute. … These pumps operate at lower speeds than centrifugal pumps. Reciprocating pumps cause intermittent flow.

What is a major advantage of centrifugal pump?

The biggest advantage of centrifugal pumps is their aforementioned simplicity. They don’t require any valves, or many moving parts. This makes them easy to produce with many different materials. It also allows them to move at high speeds with minimal maintenance.

Which pump has high efficiency?

Efficiency & Performance 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.

Why pump is used in industry?

Centrifugal pumps are used to induce flow or raise a liquid from a low level to a high level. These pumps work on a very simple mechanism. A centrifugal pump converts rotational energy, often from a motor, to energy in a moving fluid. … While passing through the impeller, the fluid is gaining both velocity and pressure.

What are the advantages of centrifugal pump over reciprocating pump?

Advantages of Centrifugal pump over Displacement (Reciprocating) pumpBecause of fewer parts centrifugal pump have less cost than reciprocating pump.Also because of fewer parts installation and maintenance are easier and cheaper as compared to reciprocating pump.More items…•

Why the centrifugal pump is called high discharge pump?

Centrifugal pump is a kinetic device. … So the liquid entering the pump receives kinetic energy from the rotating impeller. The centrifugal action of the impeller accelerates the liquid to a high velocity, transferring mechanical (rotational) energy to the liquid. So it discharges the liquid in high rate.

What are the main parts of centrifugal pump?

Some of the most common components found in centrifugal pumps are:Pump main housing.Impeller.Impeller seal.Impeller bearings.Motor.Coupling.Shaft-drive.Shaft seal.More items…
