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 4 types of pumps?
Types of Pumps
- 1). Centrifugal Pumps. These types of pumps are most commonly used worldwide.
- 2). Vertical Centrifugal Pumps.
- 3). Horizontal Centrifugal Pumps.
- 4). Submersible Pumps.
- 5). Fire Hydrant Systems.
- 1). Diaphragm Pumps.
- 2). Gear Pumps.
- 3). Peristaltic Pumps.
Which type of pump is used in water supply?
centrifugal
Most water distribution pumps are of the centrifugal type, in which a rapidly rotating impeller adds energy to the water and raises the pressure inside the pump casing. The flow rate through a centrifugal pump depends on the pressure against which it operates. The higher the pressure, the lower the flow or discharge.
What are the different types of pumps give examples?
Positive Displacement Pumps
| SUB-TYPE | EXAMPLES |
|---|---|
| Reciprocating Pump | Bladder Diaphragm Peristaltic Piston / plunger |
| Rotary Pump | Gear Screw Progressing cavity Rotary lobe Rotary vane |
What are the 3 types of centrifugal pumps?
Single-stage, Two-stage, or Multi-stage.
How many types of centrifugal pumps are there?
There are four main type classifications of centrifugal pump, with the chief distinction of each being the mechanism that drives the reciprocating diaphragm.
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 |
Why vertical pumps are used?
Pros of Vertical Centrifugal Pumps
Smaller footprint when compared with horizontal pumps. Suitable for applications that have restricted surface area. The NPSH can be altered thereby making it suitable for a wide range of applications. Suitable for liquids with high pressures and high temperatures.
What type of pump is a 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.
Which water pump is best?
Best Water Pumps for Domestic Use in India:
- Havells Hi-Flow MX2 Series 0.5 HP Centrifugal Water Pump.
- Havells Hi-Flow MX2 Series 0.5 HP Centrifugal Water Pump.
- Kirloskar 40S Mini Water Pump.
- Crompton 0.5HP SP Aquagold 50 Water Pump.
- Kirloskar KOSi-135 5 Star HP Openwell Submersible Pump.
What is difference between centrifugal pump and rotary pump?
Rotary pumps operate in a circular motion and displace a constant amount of liquid with each revolution of the pump shaft.Centrifugal pumps differ from rotary pumps in that they rely on kinetic energy rather than mechanical means to move liquid.
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.
How do I choose a pump type?
Before you can select a pump that will fit your needs, you must know four things: 1) the total head or pressure against which it must operate, 2) the desired flow rate, 3) the suction lift, and 4) characteristics of the fluid.
What are the 2 types of gear pump?
There are two basic types: external and internal. An external gear pump consists of two identical, interlocking gears supported by separate shafts. An internal gear pump has two interlocking gears of different sizes with one rotating inside the other.
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 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 API standard for pumps?
API Pump Standard Defined
In terms of pumping equipment, centrifugal and rotary positive displacement pumps used in petrochemical, gas, and petroleum industries must satisfy the requirements of the American Petroleum Institute Standard 610 for General Refinery Service.
What are peristaltic pumps used for?
Peristaltic pumps are a type of positive displacement pump used for pumping a variety of fluids. The fluid is contained within a flexible hose or tube fitted inside the pump casing.
What are 3 types of hydraulic pumps?
There are typically three types of hydraulic pump constructions found in mobile hydraulic applications. These include gear, piston, and vane; however, there are also clutch pumps, dump pumps, and pumps for refuse vehicles such as dry valve pumps and Muncie Power Products’ Live PakTM.
Where are reciprocating pumps 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.
