Using FMI Metering / Dosing Pumps and Dispensers to Combat the Spread of Zika Virus

Few things strike fear in the hearts of people like the prospect of a contracting a deadly virus.  Many virus epidemics are due to mosquitos carrying the virus and transmitting it to humans.  One virus currently being spread by mosquitos is the Zika virus, whose spread has pushed the World Health Organization to issue a Public Health Emergency of International Concern warning.

Zika not only proves to be life threatening to the first point of contact (the original patient), it also causes brain abnormalities in the fetus if it happens to afflict pregnant women.  Widespread in South America, concern has risen with the upcoming summer Olympic Games that will be taking place in Rio de Janeiro, Brazil. Steps can be taken to stop the spread of mosquitos carrying the virus, such as using Fluid Metering’s pumps to administer insectide.

Two ways to prevent Zika infected mosquito bites are: application-spray

  • Use of the right kind of mosquito repellent in areas of lush vegetation. Yards turn into great breeding grounds because the soil is moist and they have more greenery than concrete roads. Fluid Metering Inc.’s ULV Spray Equipment can dispense insecticides that attack both adult mosquitoes, as well as mosquito larvae.
  • The rigorous practice of draining standing water. A teaspoonful of standing water can breed up to 300 mosquitoes. Imagine how many of these insects can call stagnant water in your gardens, around your house or in your back yard their home? Fluid Metering Inc.’s powerful drainage and utility pumps solve this problem, sucking the liquid from your property and disposing it in ditches and trenches that can later be filled up with sand.

Fluid Metering Inc. has always pioneered innovations in the field of pumps and dispensers. Its top quality products serve myriad industries including medicine, diary and food processing, manufacturing and pollution control. Using its twin strengths of precision and power, the fight against mosquitos and the Zika virus can also be taken forward. Please contact us at to learn more.

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.

‘Get Into the Flow’ and Help Protect Our Environment

Water pollution is a global issue. Here in the U.S., the Clean Water Act was passed more than 40 years ago – in 1972 – after many years of unmonitored pollution finding its way into our nation’s waterways. According to a timeline on, “Passed in 1972, the Clean Water Act was a response to the nearly unchecked dumping of pollution into our waterways. At the time, two-thirds of the country’s lakes, rivers and coastal waters had become unsafe for fishing or swimming.”

Today, conditions have improved, but water supplies are routinely monitored, thanks to the Clean Water Act. The PBS timeline also states, “The goal of the Clean Water Act was to reduce pollution in all U.S. waters to restore and maintain the chemical, physical, and biological integrity of our nation’s waters.” Specifically, the law mandated “zero discharge of pollutants into navigable waters by 1985, and fishable and swimmable waters by 1983.”

While times have changed and water conditions have improved overall, the world’s drinking water supply still remains at risk today. Contaminated water threatens quality of life on a global scale. On its website, the Natural Resources Defense Council (NRDC) says, “Many of our water resources also lack basic protections, making them vulnerable to pollution from factory farms, industrial plants, and activities like fracking.” That’s where the measurement of water flow patterns can play a significant role.

Dye fluorometry – or water tracing – is used for tracing pollutants in our water sources, according to this article. Fluorescent dye, such as rhodamine, can measure the time of travel (TOT) for surface and ground water. The dye mimics the movement of water molecules. It indicates how water moves – which ultimately can reveal the source of contaminants and pollutants.

For the best results in water tracing studies, metering pumps should be used for precision injection of the rhodamine dye. Low current metering pumps, such as Fluid Metering’s QBG pumps, are ideal for this application because they offer:

  • Accuracy and precision – the pumps’ valveless design features only one moving part in the fluid path.
  • Inert internal components – chemically inert ceramics and fluorocarbon wetted parts will not skew results.
  • Low current operation – the QBG pump runs at low current and will operate on battery power for extended periods of time, making it perfect for environmental studies in remote locations.

Through water tracing efforts and the measurement of water flow, we can monitor our waterways. Our future – and the future of our grandchildren – depends on the protection and sustainability of the world’s water supply, and the protection of our environment, in general.
