Industry Information
View A Video on Centrifugal Pumps - A Quick Introduction

Centrifugal pumps are designed to increase the pressure of a fluid through interaction with rotational kinetic energy. The pumps are simple devices that consist of a stationary pump and an impeller mounted on a rotating shaft inside a volute, or casing.

In a centrifugal pump, mechanical force powers its shaft, and it rotates, turning the impeller with it. The vanes or blades on the impeller impart kinetic energy to the fluid in pump and as the impeller spins, the fluid works its way to the tips of the vanes. The volute increases in size as it extends from the impeller and it gradually reduces the speed of the fluid while increasing its pressure. A discharge opening in the volute channels the fluid out of the pump. Centrifugal pumps are typically constructed of cast iron, aluminum or high grade stainless steel that can withstand harsh conditions or hazardous materials. This kind of pump offers a uniform rate of flow and can accommodate solid and liquid mixtures. At the same time, however, centrifugal pumps cannot function well at high heads, or pressures. Many need to be primed and are prone to becoming air bound, a circumstance in which the pump is too full of air to form a vacuum. If no vacuum forms, then no water will enter the pump.

Centrifugal pumps transport a variety of materials and can be identified by the liquid or gas they handle. Chemical pumps are able to process commercial and industrial abrasives, chemicals and corrosive materials such as bleach, acid, oil, resin and more. Trash pumps are designed to pump hundreds or thousands gallons of water per minute, including water that is polluted with sand, twigs and other debris. Trash pumps are also known as sludge pumps, waste water pumps or sewage pumps, depending on the specific application. In order to impart kinetic energy to thick or viscous material, the impeller has deep vanes and a large volute discharge opening. Water pumps are used in all applications of water transfer, be it commercial, industrial, residential or wastewater. Centrifugal water pumps can be lightweight, general purpose, multipurpose and high-pressure depending on the intended use. Within this category are sump pumps and well pumps. Sump pumps are designed to empty accumulated water from a low-lying surface. They are used for residential and industrial drainage purposes and to prevent flooding. Well pumps are centrifugal pumps that transport water from an underground source to another location inside a building or structure. Depending on the pipe length, the amount of horsepower needed varies; sometimes these pumps are combined with a pressure tank to distribute water to all parts of a building.

Because centrifugal pumps work with a variety of materials, there are different design options that can maximize their usefulness in different situations. Axial flow pumps have a vertical shaft attached to the perpendicular impeller, forcing the liquid upwards by pressure caused by the lifting action of the vanes on the impeller. Jet pumps help enhance the suction ability of an existing centrifugal pump. Submersible pumps are installed underground in a fluid source which is almost always water. They are self-priming pumps because they do not need to remove air from the suction line in order to provide uninterrupted water flow; water is retained and circulated to prevent the pump from becoming air bound. These vertical pumps are usually designed in a close-coupled form where the motor and pump are close to each other so the assembly can be lowered into a drilled well hole. Submersible and vertical pumps are often powered by electricity. The power cord is held safely in a strong and durable casing. Electric pumps are usually hard to service; replacing a battery in an underground pump would be no small feat. Some electric pumps are small and provide minimum power. 12 volt pumps are a quick and low cost way to lift water. The pump diameter for a 12 volt centrifugal pump is often a few inches and the whole assembly can usually be lifted by a single person.

Centrifugal pumps are becoming more powerful and specialized, capable of lifting fluids in the many industries that require it. New technologies and innovations result in new applications and more effective uses. For example, jet pumps are becoming increasingly unnecessary due to the development of submersible pumps. Self-priming pumps are an improvement and help decrease startup time. Hygienic centrifugal pumps are available for situations that necessitate gentle product handling, easy maintenance and a high degree of cleanability. Industrial pumps are now able to deliver head capacities of 500 feet or more in addition to a flow rate of 40,000 gallons per minute. Improvements in filters and suction ability prevent pumps from clogging or slowing down when working with solids in the liquid like in trash pumps. Efficiency is also important; large pumps require massive amounts of power in order for the impeller to rotate at high speeds. Materials also contribute to faster and more efficient pumps. Fluorocarbons and thermoplastics are gaining popularity for seals and parts and the metals already in use are of high grades that resist corrosion, leaking and other forms of damage.

Centrifugal Pumps Types

  • 12 volt pumps use centrifugal force to increase the pressure of a liquid by converting mechanical energy into rotational kinetic energy.
  • Axial flow pumps are machines that convert mechanical energy into kinetic energy by increasing the pressure of a liquid through centrifugal force.
  • Chemical pumps are made of corrosive-resistant materials.
  • Close-coupled pumps are directly connected to a power unit but do not have any less gearing or shafting.
  • Dewatering pumps are self-priming and capable of handling clear water and water containing small particulate matter up to .25” in diameter. Some dewatering pumps are completely submersible and can operate from any position, including upside down.
  • Double suction pumps are a type of radial flow pump in which the fluid enters the impeller from both sides. Due to the extending of the shaft into the suction passage, double suction pumps are limited to pumping clear liquids. 
  • An electric pump is a machine that uses electrical power to increase the pressure of a liquid through centrifugal force.
  • A jet pump is a centrifugal pump that increases water pressure in shallow and deep wells by converting the mechanical energy of an impeller into kinetic energy.
  • Mixed flow pumps are designed with wide unblocked passageways and are an intermediate pump between radial and axial flow pumps. Mixed flow pumps develop the pressure partially with centrifugal force and partially with the lift of the impeller vanes on the liquid.
  • Multistage pumps, which can be either horizontal or vertical, consist of two or more pumps of similar capacity that discharge into each other in a series. Progressively the pumps develop a total head, the sum of the heads that each pump has developed. A common shaft with several impellers, each with its own volute, is rotated by a power supply, building up pressure in stages.
  • Radial flow pumps take in liquid through the center of the impeller and move it out along the impeller blades at a 90-degree angle to the pump shaft. Radial flow pumps develop the pressure only with centrifugal force.
  • Self-priming pumps are centrifugal pumps that retain a small volume of fluid in order to start up without requiring outside attention to clear their passages of air.
  • Semi-trash pumps have smaller openings and cannot handle as great of an amount of solids or large solids as trash pumps can. There is no industry standard dividing semi-trash pumps from trash pumps, so both may be referred to simply as trash pumps.
  • Single-end suction pumps are a type of radial flow pump in which the fluid enters the impeller from one side, and the shaft does not reach into the suction passage. Single-end suction pumps are used in applications where there are large solids, such as rags and trash, that would normally clog the pump.
  • Submersible pumps are designed to run inside the water source being pumped, eliminating the suction lift limitations common with other types of pumps. Suction pumps are ideal for private use, such as in well systems or irrigation.
  • Sump pumps are used to pump water or other fluids from low-laying surfaces.
  • Trash pumps are heavy-duty centrifugal pumps that are designed to pump hundreds or even thousands of gallons of water per minute, which contains large solids, such as twigs, sand, mud, soft solids and trash. Trash pumps have deeper impeller vanes, incorporated with a larger volute discharge opening, and are used in such applications as construction and agricultural sites.
  • Two-speed centrifugal pumps turn the shaft and impeller at two different rpm levels with a two-speed motor, allowing for optional pump capacity.
  • Vertical cantilever pumps are designed to have only the casing and the impeller submerged in the pumpage for priming and the support bearings for the rotating element in a dry environment. Vertical cantilever pumps have no throttle or bumper bushings or any rings at the impeller or submerged below the maximum normal water level, and they are used in applications, such as a sump or tank, in which it is necessary not to have a bearing in the pumpage.
  • Vertical pumps use centrifugal force to convert mechanical energy into kinetic energy and increase the pressure a liquid as it travel upwards through a pipe.
  • Vortex pumps are inefficiently designed pumps in which the impeller is recessed into the volute. However, vortex pumps are practical in applications that require pumping of excessive solids.
  • Water pumps use an electric motor to move water.
  • Well pumps extract water from wells.


Centrifugal Pumps Terms

Air Bound – A circumstance in which a centrifugal body is so full of air that a vacuum can no longer be formed. Without vacuum, water cannot flow into the pump.
Atmospheric Pressure – The force applied by the atmosphere to the surface of the earth. Atmospheric pressure, the standard of which is 14.7 lbs per square inch, affects the operation of a pump.
Capacity – A term describing how much water a pump can process. Capacity is typically articulated as gallons per hour (gph) or gallons per minute (gpm).
Cavitation – An undesirable condition in which vacuum pockets form within the pump. The air pockets eventually implode under pressure, resulting in the pitting of the impeller and volute surfaces.
Centrifugal Force – The force that causes a substance to move away from its center of rotation.
Check Valve – An apparatus in a discharge or suction line that permits flow in only one direction so as to prevent reverse flow and isolate the material being pumped.
Dewatering – The removal of unwanted dirty or clear water containing no hazardous materials.
Diffuser – A stationary casing, like a volute, that houses the moving impeller. Diffusers are compact in design, enabling the pump to create higher pressure heads.
Discharge Hose – A collapsible hose that moves the discharged water from the pump.
Discharge Port – Also called the “outlet,” it is the point at which the discharge pipe or hose is connected to the pump.
Drain Plugs – Detachable plugs for draining water from the pump when it is inactive.
Dynamic – Acting by motion, not weight, in contrast to static.
Dynamic Head – The head or pressure force against which the pump operates.
Dynamic Suction Head – Also known as “total suction head,” it is the combination of the static suction lift and the suction friction loss in the suction line.
Effluent – Partially or completely treated wastewater or other liquid that flows out of a septic tank or treatment unit.
Flapper Valve – Rubber molded around a steel weight that seals off the inlet or outlet, preventing water from either entering or exiting the pump at the wrong time.
Flow Rate – The required amount of gallons per minute (gpm) of pump flow. Flow can also be expressed in gallons per hour (gph) and in million gallons per day (mdg).
Head – The measure of the pressure or force exerted by a fluid in a hydraulic system. Also, the height of fluid above any point, taking into account losses or gains in pressure due to gravity and friction as water travels through a system, measured in lbs per square inch (psi) or feet of water.
Impeller – A rotating disk with vanes of varying amounts attached to the “r” drive shaft that creates centrifugal force within the pump casing of a centrifugal pump. Impellers can be open or closed.
Impeller Eye – The center of the impeller and the point at which fluid flows into the impeller.
Impeller Vanes – Pump components located on the impeller between the eye and the discharge side of the impeller. Impeller vanes direct the flow of the liquid to the outside diameter of the impeller.
Intake – The flow, or the rate of flow, into a pump.
Mechanical Seal – A device that forms a seal between the pump and the engine or motor and prevents water from getting into the engine or motor.
Net Positive Suction Head Available (NPSHA) – A measure of the absolute pressure of the liquid at the inlet of the pump.
Prime – Allowing the pump to disperse all air from the influent line of a circulating system by causing fluid to start flowing once again. Priming the pump is usually accomplished by either manually filing the volute or turning the pump on.
Pump Housing – The body or casing of a pump, which may be made of plastic, cast-iron, stainless steel or aluminum.
Shock Mounts Rubber vibration-dampening devices that are mounted on the engine to prevent the pump from “walking away.”
Static – Acting by weight not motion, in contrast to dynamic.
Strainer Basket – A plastic mesh basket that traps debris to prevent its reaching the impeller. Strainer baskets are located in the strainer pot.
Strainer Pot – The housing of the strainer basket that is located on the influent side of the pump. Strainer pots serve as a priming chamber.
Suction Hose – A reinforced hose through which water flows into the suction end of a pump.
Vane Passing Syndrome – A type of cavitation resulting from the small size of the impeller or low cutwater clearance.
Vent – The act of removing air or gas from a system. Stuffing boxes in vertical pumps must be vented to prevent the seal faces from running dry.
Viscosity – The resistance to flow of a liquid at a particular temperature. High viscosity liquids, such as motor oil, are thick and tend to flow slower than water, a low viscosity liquid.
Volute – Stationary casing of a centrifugal pump that separates air and water and in which the impeller rotates. Volutes are spiral-shaped  in order to facilitate the partial conversion of the velocity (kinetic) energy into pressure head as the water leaves the impeller.
Vortexing Liquid – Creates a “whirlpool effect” that can cause air to be drawn into the suction of the pump.
Weep Hole – A small opening located on the underside of the pump at which point the engine joins the pump. Weep holes provide the means to quick detection of a leak before water seeps into the oil sump of the engine.
