Centrifugal Pumps & Centrifugal Pump Manufacturers
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.
