Conquering the Challenges of Metering Concentrated Chemicals

Why metering highly concentrated chemicals are being used more frequently?

Various industries are seeing a dramatic increase in their use of high-concentration chemicals for countless different applications. For example, Pesticide & mosquito sprayers have found that the cost of transporting and storing large amounts of dilute malathion is significantly higher than shipping small concentrated volumes and diluting them on-site. The same is true for sodium hypochlorite, a disinfectant chemical used for water treatment, and industrial cleaning chemicals like the ones used in automatic car wash equipment. In most cases, users of dilute chemicals find that they are basically paying to ship and store large drums of chemicals that consist mostly of water.

The power generation industry also utilizes low-flow process metering of concentrated chemicals for many different applications, such as metering bromine into cooling towers for algae control, injecting hydrazine into boiler feed-lines for corrosion management, and more recently, a number of fuel cell fluidic applications.

However, metering chemicals at high concentrations comes with many challenges. As the concentration increases, the chemical feed rates must significantly decrease. At these low flows, the metering precision and long-term accuracy become more difficult to achieve. High-concentration chemicals typically have intensified corrosive properties to contend with as well.

The CeramPump® from Fluid Metering, Inc. having chemically inert, sapphire-hard ceramic internals can accommodate all of these application challenges. The valveless design, having only one moving part made of sapphire-hard ceramics, will maintain drift-free accuracy of better than 1% for millions of maintenance-free cycles, without the need for recalibration. These features make the CeramPump® ideal for low and micro-volume process applications. In addition, long-term drift-free accuracy makes the CeramPump® metering pumps especially suited for low flow process metering of concentrated chemicals applications. These chemical metering pumps are available in a variety of configurations ranging from simple lab pumps to complete programmable metering and dispensing systems, as well as many compact OEM designs for medical, analytical, and process instrumentation.

Precision Fluid Dispensing at the MD&M Medical Design Exhibition in New York City

Throughout the year Fluid Metering , Inc. (FMI) exhibits at a variety of trade shows which showcase our unique valveless metering technology.  Our interactive display at these shows is staffed by experienced application personnel dedicated to provide solutions for process, production and OEM fluid control applications. On June 10-12 FMI will be exhibiting at the Medical Design & Manufacturing East Exhibition (MD&M East) at the Javits Center in New York City to demonstrate the benefits of our metering pumps.

One such benefit of our metering pumps for the medical industry is its unique ability to meet the challenge of precision production dispensing of bonding fluids used for assembly of disposable medical components.  These single use components include syringes, IV tubing sets, catheters, and blood collection assemblies, just to name a few.  Common bonding agents include a variety of adhesive formulations, as well as using solvents to chemically “weld” polymer components together. No matter which process is chosen, accurate dispensing is critical to the overall quality and integrity of the finished disposable assembly, as well as the overall function of device or instrument with which it is used.

Fluid Metering’s precision CeramPump® was developed to answer just this challenge and offers a pump head with internal components made from chemically inert, sapphire-hard ceramics. These pump heads are ideal for dispensing cyclohexanone, cyanoacrylates, UV curable adhesives, and 2-part epoxy bonding agents used to manufacture disposable medical components.
