Since centrifugal pumps can deliver high quantities of fluid, they are often used for water supply and water treatment. In water works, distribution networks, processing and also in building services engineering, radial pumps and axial-flow pumps ensure that the base load demand is covered reliably. But they can handle much more than just water. They are usable for nearly every low-viscouls fluid in all industries.
Peripheral pumps serve the opposite purpose: If there are particularly small volumes to handle, the peripheral pump, which is significantly smaller than the radial pumps, can demonstrate its advantages – especially if there is high operating pressure. This is the case, for example, in many processes in the chemical industry, but also for pressure increase and cooling.
Do you need to handle media whose temperature is close to the boiling point or higher gas content? Then the side channel pump is often the best choice. The pump can reach very low NPSH values so that it is perfectly suited for media such as condensate, refrigerants or liquid gases.
But despite the large portfolio of vendors, individual applications always produce requirements that cannot be met by common pump types. Such applications are predestined for special pumps. They are used in the chemical industry, for example, where special media must be handled under extreme conditions. Examples include sulfuric acid, contaminated chemicals and fertilizers. Many of these fluids can be handled with plastic pumps: In contrast to metal alloys, certain plastics can cover the entire concentration range of sulfuric acid. Pumps whose components in contact with media are made of plastics can deliver the acid without any problems.
If leakproofness is particularly important, for example, when handling extremely toxic media, then the canned motor pump is often the pump of choice. Its special design principle separates the rotor space from the stator of the drive motor: As a result, the pump operates hermetically, ensuring safe operation, even for critical media.
Drum and Container pumps are often used for transferring, filling or emptying drums, IBC’s or other containers. They are characterized by their flexible application possibilities and nevertheless high flow rates.
