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.

Which is an example of reciprocating pump?

Easy explanation: Hand pump is the example of a reciprocating pump. Reciprocating pumps when made use inside a boiler. They are continuously run by steam from the same boiler to which the water is fed. Water is pumped by reciprocating action.

What are the applications of single acting reciprocating pump?

  • Gas industries.
  • Petrochemical industries.
  • Oil refineries.
  • Vehicle water servicing centers etc.

When reciprocating and centrifugal pump is used?

S. No.Centrifugal pump4.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.

How do reciprocating pumps 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.

What type of pump is used in houses?

When it comes to pumping types, there are two main types that are pumps for domestic and agricultural water. These two types are further divided into categories, which include: water pump, irrigation pump, centrifugal pump, submersible pumps, etc. We use domestic to draw water for our domestic purposes.

What type of flow does reciprocating pump have?

Explanation: The reciprocating pump has a continuous flow. It has a constant discharge even if head on the delivery side varies. Explanation: The reciprocating pump runs at a low speed. Its speed is less than 30m/min.

Which pump is best centrifugal or reciprocating?

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.

Which type of pump is used in industry?

Centrifugal pumps: These are the most common type of pumps used in the chemical industry. They are highly efficient pumps, simple in design and operation, and generally less expensive than other types of pumps.

What are the advantages and disadvantages of a reciprocating pump?
  • This pump is self-priming – Not require filling the cylinders by starting.
  • This pump can work in wide pressure range.
  • Priming is not necessary in pump.
  • Provide high pressure at outlet.
  • Provide elevated suction lift.
  • They are use for air also.

Why reciprocating pump is called positive displacement pump?

Why are reciprocating pumps also called positive displacement pumps? … Positive displacement pumps have an expanding cavity during suction and a decreasing or collapsing cavity during discharge.

What is the other name of reciprocating pump?

A reciprocating pump is a class of positive-displacement pumps that includes the piston pump, plunger pump, and diaphragm pump. Well maintained, reciprocating pumps can last for decades. Unmaintained, however, they can succumb to wear and tear.

What are the advantages of reciprocating pump?

  • Reciprocating pump can deliver the required flow rate very precisely.
  • It gives a continuous rate of discharge.
  • It can deliver fluid at very high pressure.
  • No priming is needed in the reciprocating pump.

What is the use of pump?

Today, the pump is used for irrigation, water supply, gasoline supply, air conditioning systems, refrigeration (usually called a compressor), chemical movement, sewage movement, flood control, marine services, etc.

What is the efficiency of reciprocating pump?

The overall efficiency of a reciprocating pump unit is generally above 85 percent throughout its full operating range (see Figure 4).

Why Priming is important in reciprocating pumps?

The main objective of priming a pump is to remove the gas present. So, if the air or other gases present inside the pump casing and suction line, it must be primed before starting. But if the pump suction line and the casing are already filled with liquid during start-up, priming is not required.

What is reciprocating pump PDF?

A reciprocating pump is a positive displacement one which works on the principle of a reversing piston motion within a cylinder drawing in liquid during forward stroke, and delivering it under pressure during return or backward stroke. Page 2.

How is speed measured in a reciprocating pump?

Performance & Speed The flow of a reciprocating pump is determined by the fixed displaced volume inside its liquid cylinder and the rate (pump speed or rpm) at which the plunger/piston can move this fluid through the system. These are fixed-volume machines.

Which pump is best for House?

Which pump is used for irrigation?

Volute pumps are widely used in irrigation. They are of simple construction, the only moving parts being the impeller and shaft. The impeller is housed in a casing (volute). The volute pump most often used for irrigation purposes is the (radial-flow) centrifugal pump.

Which pump is used in Borewell?

A Submersible Pump is a device with a sealed motor which is completely submerged in water bodies, especially open wells and bore wells.

Which pump is used for high pressure?

Multi-stage centrifugal pumps tend to be used for applications that require higher pressure or pressure head. Diaphragm type pumps are generally deployed within the following ranges: Flow rate ranges between 20 to 750,000 lpm.

What are the two main types of pumps?

Pumps are divided into 2 major categories: Dynamic and Positive Displacement (aka Displacement).

Which pump is more efficiency?

Positive displacement pumps are able to handle variations in pressure, flow and viscosity and remain efficient, unlike centrifugal pumps which do not operate well off the centre of their curve.

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 pump and turbine?

A pump absorbs useful energy and converts it to kinetic energy and gives it to a fluid stream. The turbine does the exact opposite as it absorbs energy from a fluid stream and converts it to work. A pump increases the energy of the fluid stream whereas a turbine decreases the energy.

What is main component of reciprocating pump?

A hollow cylinder made of steel alloy or cast iron. Arrangement of piston and piston rod is inside this cylinder. Suction and release of liquid is takes place in this so, both suction and delivery pipes along with valves are connected to this cylinder.

What is the advantage of centrifugal pump over reciprocating pump?

Floor Space and Capacity. 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 slip in reciprocating pump?

Slip is the loss of pumping capacity due to fluid leaking back through a pump from the discharge side to the inlet side. It can affect the efficiency of all types of pumps although the actual causes may be very different.

What is difference between positive and non positive displacement pump?
