There are two basic types of water pumps: centrifugal and positive displacement. Both types are designed to move water from one place to another continuously. A centrifugal water pump uses a rotating impeller to move water into the pump and pressurize the discharge flow.
What are the different types of water pumps?
Application of reciprocating or positive displacement pump
| Type of PD Pump | Application |
|---|---|
| Piston pump | Water high-pressure washing; other low viscosity liquids; oil production; paint spraying |
| Plunger pump | |
| Diaphragm pump | Used for metering or dispensing; spraying/cleaning, water treatment; paints, oils; corrosive liquids |

What are the 2 main classification of pumps?
Pumps are divided into 2 major categories: Dynamic and Positive Displacement (aka Displacement).
What are the 3 types of centrifugal pumps?
Single-stage, Two-stage, or Multi-stage.

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.
What are types of centrifugal pump?
What are the main applications for centrifugal pumps?
| Type of centrifugal pump | Application |
|---|---|
| Chopper/grinder pump | Waste water in industrial, chemical and food processing/ sewage |
| Circulator pump | Heating, ventilation and air conditioning |
| Multistage pump | High pressure applications |
| Cryogenic pump | Liquid natural gas, coolants |
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.
Which pump is used for high head?
Centrifugal pumps
If the mechanical energy is converted into pressure energy by means of the centrifugal force acting on the fluid, the hydraulic machine is called a centrifugal pump.
Explanation:
| Centrifugal pumps | Reciprocating pumps |
|---|---|
| It is used for large discharge through smaller heads | It is meant for a small discharge and high heads |
How many types of vacuum pumps are there?
There are two basic categories of vacuum pump: Gas Transfer Pumps and entrapment or capture pumps (Figure 1).
Which pump is used in homes?
Common Pump Features & Benefits
| Pedestal Sump Pumps | Submersible Sump Pumps | Pool Pumps |
|---|---|---|
| Pedestal pumps are positioned with the pump motor out of the water and above the sump basin. | Submersible sump pumps are put underwater in your sump pump basin. | Water pumps send water through the filter, heater and chlorinator. |
What is pump principle?
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 impeller in pump?
An impeller is a rotating iron or steel disc with vanes in a centrifugal pump. Impellers transfer energy from the motor that drives the pump to the fluid being pumped by accelerating the fluid radially outwards from the centre of rotation.
What is a multi stage pump?
Multistage pumps are defined as pumps in which the fluid flows through several impellers fitted in series. The head of a single-stage centrifugal pump is largely governed by the type of impeller and the circumferential speed.The individual stages of a multistage pump do not necessarily have to be arranged in tandem.
What is the 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.
How do I choose a good water pump?
What are the factors to consider when buying a water pump?
- Flow rate. This is generally the effectiveness of the water pump.
- The size of the inlet. Most pumps have an inlet size of between 1 to 6 inches but in some cases, it can be more.
- Maximum head and pressure.
- The quality of the pump.
- The type of water to be pumped.
What is the difference between 0.5 HP and 1HP water pump?
For example if an 0.5 HP motor with discharge rate of 200 litres per hour takes 2 hours to lift the water, then an 1 HP pump with higher discharge rate 400 litres per hour can complete the task in less than 1 hour.
What type of motor is used in water pumps?
induction motor
Although there are various types of electric motors in use todaysplit phase, shaded pole, and synchronous motorsthe most common type of motors used in water well and water works is the induction motor.
Which pump is best centrifugal or reciprocating?
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.
Which pump is used for viscous fluid?
Generally speaking, centrifugal pumps are most suitable for low viscosity fluids, since the pumping action generates high liquid shear. As viscosity increases, pump performance diminishes due to friction loss.
