7 Benefits Of Centrifugal Chemical Pumps
Posted by Admin on May, 04, 2023
Centrifugal chemical pumps are ideal for many applications, from filtration and circulation to storage and unloading.
Due to their harsh nature, corrosive chemicals must be handled carefully. As designers establish their systems, they must select pumps that are constructed to withstand the specific corrosive chemicals involved in their process.
Centrifugal Chemical Pump Types
Centrifugal pumps are available to transfer a wide range of flows. Using rotational energy supplied by an impeller, these pumps are able to move liquids safely and efficiently. Centrifugal chemical pumps are designed to transfer liquids that other pumps cannot safely handle
Centrifugal pumps transfer liquids and can handle corrosive chemicals.
Centrifugal chemical pumps are manufactured in two main styles: mechanically sealed and magnetically driven. These designs are distinct and are appropriate for different applications.
Pumps With Mechanical Seals
A centrifugal pump features an internal rotating impeller with a portion that connects to the motor through an opening in the pump housing. To prevent leakage, a mechanical seal is used for this opening. These are typically made of ceramic, silicon carbide or carbon rings that are carefully designed to seal the pump preventing leakage. One ring rotates as the shaft turns, while the other remains stationary in the pump. As the fluid travels through the pump, a small amount moves between these two seal faces to provide lubrication.
The main advantage to this type of pump is the initial purchase price. Compared to other types of pumps, the initial investment is typically lower. A secondary advantage is the potential to handle some solids
Magnetic-Drive Centrifugal Pumps
As the name implies, magnetic-drive (mag-drive) pumps are driven by magnets. This eliminates the direct connection between the impeller and the motor shaft, effectively eliminating the need for a seal. Magnets are mounted on the motor shaft to transfer the motor power through a solid barrier to other magnets inside the pump, which rotate the impeller.
The key advantage to this pump style is the lack of mechanical seal. With no seal to wear out or leak, this pump style offers lower maintenance and greater longevity than mechanically sealed pumps, and also, some models feature run-dry capability not commonly found among mechanically
Centrifugal Chemical Pump Benefits
- Corrosion Resistance
This benefit creates two advantages. First, the pumps allow manufacturers and processors to transfer a wide variety of fluids, even those that would quickly cause corrosion in other pumps.
Second, the pumps offer long service life. Even when used for extremely
corrosive chemicals, the pumps are able to withstand these conditions and deliver enhanced return on investment (ROI).
- Energy Efficiency
Centrifugal chemical pumps rank high in energy efficiency compared to other pumping technologies. Their efficiency reduces costs both in the short term and over the life span of each unit.
- Smooth Flow
Some pumps produce pulsing flow. Centrifugal chemical pumps avoid pulsing.
- Proven Reliability
Centrifugal chemical pumps are a solid choice when reliability is critical. Evaluate design and construction features to ensure the specified pump will be durable enough to operate under the most extreme conditions in the planned application.
- Low Maintenance
Despite long life spans, some pumps may require frequent routine maintenance that can make them costly to operate. Fortunately, centrifugal chemical pumps have low routine maintenance requirements.
- Size Versatility
Centrifugal chemical pumps are available in a wide range of sizes. The various models can accommodate flow rates ranging from less than 1 gallon per minute (gpm) (1 liter per minute [lpm]) to greater than 1,400 gpm (318 cubic meters per hour [m3/hr]).
- Application Versatility
The same pump configuration is not suitable for every application. With centrifugal chemical pumps, various configurations are available to provide solutions for multiple applications. These versatile pumps are available in three configurations:
- Flooded suction—These can be used when the liquid supply level is above the pump’s centerline or impeller eye.
- Self-priming—These can be used when the liquid supply level is below the pump’s centerline or impeller eye.
- Vertical—These pumps are typically submerged in the fluid, making them suitable for applications where space is limited. Some manufacturers offer standard, nonsubmergible pumps that can be mounted vertically outside the tank to save space.
Furthermore, the option of mechanical seal or magnetic drive sealless designs adds to the versatility of these pumps. These two constructions cover a full range of applications. This diversity also covers a range of budgets, making it easier to find a pump that is suitable for each unique use.
