Working with Hydrogen Peroxide

One area where our pumps excel is in metering concentrated hydrogen peroxide. Hydrogen peroxide is used across a variety of applications, including:

  • Use during the aseptic packaging process for a variety of foods and products
  • Low-temperature sterilization for clean rooms and hospital operating rooms
  • Component and instrument sterilization
  • Sporicidal activity
  • Cosmetic applications including hair and teeth bleaching
  • Production of sodium percarbonate and sodium perborate

Unreliable or imprecise metering of hydrogen peroxide can lead to issues.  These include failure to properly sterilize, or an overdose of hydrogen peroxide that could cause contamination.

Our pumps utilize a ceramic piston as the only moving part, meaning that it is the only moving part that is in contact with the fluid. We use ceramic because it is chemically inert and dimensionally stable, which ensures that over time it can withstand chemicals, as well as any wear and tear. The pumps use our CeramPump® pumping principle that uses the ceramic piston for both pumping and valving functions, allowing for a compact design that does not require check valves. This in turn reduces the need for maintenance, while allowing for the precision you require without a need for regular recalibration.

Of course, working with hydrogen peroxide is not the only way that our metering pumps can be used. At Fluid Metering, Inc., we provide a variety of pumps, available in a wide range of laboratory, production, process, and OEM instrumentation applications and can help you figure out the right pump for your need. Simple, complex, fixed, or variable, we can help you choose the correct equipment, including hazardous duty pumps.

Metering Pumps in the Automotive Industry

Metering pumps have a wide array of uses, and plenty of industries rely on them. From medical to industrial, the constant, precise flow provided by metering pumps allows for exact, efficient operations and the ability to ensure consistency over a wide range of products or in a single product over a long period of time. One industry that uses metering pumps extensively is the automotive industry, where the need to use precisely measured and constantly flowing liquids is vital.

The uses of metering pumps in the automotive industry include the following:

  • Hydrogen fuel cell research and development for both the humidification and fuel injector systems.
  • Encapsulating coating materials in the manufacture of stator, armatures, and distributors – this can include anti-corrosives, lubricants, and more.
  • Verifying gasoline octane ratings and adding octane to fuels used in vehicles, as well as adding anti-corrosives, colorants, and other additives to the fuels that automobiles use every day.
  • Automotive paint spraying, providing even flow and measured amounts for consistent application. These pumps provide a flow that prevents any dead spots in the paint job or any heavy spots. By having the smallest of tolerances, this makes for reproducible quality across every vehicle, so the automotive line shows consistency and quality.
  • Usage in the machining area, as parts of machine tools, in chiller applications, filtration of water, and the washing of parts. The precision of a metering pump ensures efficient fluid output in all of these areas, optimizing fluid usage.
  • Surface cleaning, where the ability to run a range of temperatures through the pumps and the durability of the parts can allow the precise use of hot or cold cleaning solutions, as well as a range of chemicals.
  • Dispensing insulating materials evenly throughout an automobile, including sound-insulation, noise-dampening, and temperature insulation. This can help to insure that sound reduction is at a maximum, or that the proper components are protected by the proper amount of insulation.

Here at Fluid Metering, our metered pumps are designed with precision in mind, and are perfect for automotive applications and other industries such as food and dairy, cosmetic and hygiene, medical, industrial and so many more.  Reliable, durable, and manufactured with attention to detail, we can customize them to meet the needs of your processes.

Solvent and Adhesive Dispensers for Medical Component Assembly

Medical devices are becoming increasingly complicated and a patient’s life often depends on their quality. The device assembly, even for disposable devices, requires an unprecedented standard, with each component made as closely as possible to design specification. In fact, inconsistent manufacturing could have critical consequences that not only affects the function of the device but also the patient’s health.

Medical devices assemblies and sub-assemblies can be put together by mechanical – screws – or chemical bonds – solvent welding or adhesive bonding. Solvent welding is a method of bonding polymer components with a solvent, such as cyclohexanone, to chemically soften the surface and allow them to bond together. Adhesive bonding is a joining technique that uses adhesives like acrylics and epoxies to permanently join components.

Both joining methods require precise and accurately dispensed solvent or adhesive, and at Fluid Metering we developed the CeramPump to meet this challenge. Unlike other pumps, the CeramPump’s design features a valveless reciprocating and rotating piston that is insensitive to viscosity and fully made out of ceramic, making it chemically inert and allowing it to dispense a broad range of aggressive fluids including cyclohexanone, acrylic cement, 2-part epoxy bonding agents, and more.

The CeramPump is extremely accurate (1.0%) and precise (0.5%) and is particularly well suited for the microliter range. Accuracy – how repeatable is the amount dispensed – is incredibility important the quality of the product, in fact, too  little product may result in partial bonding, too much adhesive may occlude the tubing orifice, and too much solvent may affect the structural integrity of the components.

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.
