Metering Pumps for Mosquito Control

Mosquitoes are annoying. Their stings are itchy and cause swelling and they can even transmit diseases like West Nile Virus, Dengue Fever, and Malaria. This is obviously a problem we all want to avoid, and thankfully many municipalities have taken up the task of protecting us.

For many years, federal, state and local agencies have trusted Fluid Metering’s pumps to help administer the insecticide. In years past, Thermal Fog was used but since it burned diesel fuel alongside the insecticide, it was both expensive and not environmentally safe. Fortunately, Ultra-Low Volume (ULV) aerosol technology was developed. ULV uses compressed air and a very accurate metering pump to inject the insecticide into the fluid stream. This method reduces costs and is much more environmentally friendly.

ULV sprayers work by dispensing very small aerosol droplets that stay in the air and kill flying mosquitoes on contact. This application can utilize a very small amount of active pesticides while covering a large area. At roughly 3 oz. an acre, the risk to humans and the environment is very small.

FMI’s unique valveless piston pumps have proven ideal for ULV fluid control. Sapphire-hard internal ceramics and the elimination of valves found in conventional pump designs virtually eliminate routine maintenance and downtime while improving precision to 1%. Variable speed DC drives are easily integrated to control flow rate proportional to vehicle speed. Flow rates are adjustable up to 2,300 ml/min with 1% precision and pressures up to 100 psi.

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.

Valveless Metering to Help Combat Toxic Algae Blooms

Algae is a natural part of our world, its genus comprises organisms that vary from small, singled-celled forms to complex multicellular entities. Algae is prolific and can be found in most environments, from freshwater to hot springs, highly acidic fluids, even snow and ice. Normally, algae serve an important purpose in aquatic life by providing organic matter at the base of the food chain and by producing oxygen. However, toxic algae can form and create Harmful Algal Blooms or HABs which grow and thrive in warm, calm, nutrient-rich water. Under these conditions, the algae bloom produce toxins, which can be harmful to people, animals, fisheries, and wreak havoc on entire ecosystems. One of the main sources that contribute to HABs is the effluent produced by wastewater treatment plants. The effluent contains high levels of ammonia, which through a process of bacterial degradation is converted to nitrates. Many wastewater treatment plants use a process known as “denitrification”, in which nitrates are reduced to nitrogen gas. The gas can then be vented into the atmosphere instead of being released into waterways.  There are several common denitrification processes, including pre-treatment basins, aeration tanks, and blowers. However, one of the most cost-effective options is with the use of methanol.

Methanol is most commonly known as a fuel, but it’s also highly prized by industry for the many methanol derivatives that it’s used to make. Methanol is a volatile; it’s colorless, flammable, and biodegradable, and in wastewater applications it acts as the carbon source that breaks down the nitrates.

Because of its volatility, wastewater treatment facilities that use methanol will also need to select metering pumps that are specially designed monitoring to dispense the chemical. They must have features such as chemical compatibility of wetted parts and electrical ratings for the area where the pump is being installed.

Ideally suited for the metering of methanol and many other chemicals is our CeramPump® line of valveless metering pumps. This innovative product has only one moving part and is constructed from inert and corrosion resistant ceramic parts, which provides a number of advantages. It is highly reliable and extremely precise, with an output variation of only ±1% of set value. This level of precision makes CeramPump® well suited to the low flow volume requirements in industrial and wastewater treatment applications.

3 Challenges that Affect Food Consistency

According to the Food and Agriculture Organization of the United Nations, per-capita global food consumption will rise from the 2015 amount of 2940 kilocalories per day to 3050 by 2030 (3050 kilocalories = 0.871 lbs.). Now consider that the world population will grow to approximately 8.5 billion by 2030. This means that globally food producers will need to provide almost 4.9 million tons of food per day.

To keep up with the rising demand, it goes without saying that the food industry must ensure that its products are safe and nutritious. This means that food manufacturers will have to economically provide food recipes that are repeatable and consistent. Quality, flavor, and shelf-life are the three factors that have the greatest effect on the profitability of modern food production. To maintain each factor, recipes must have ingredients that are precisely metered.

  1. Quality – Consumers demand high-quality food and manufacturers can implement a variety of measures to ensure it. Additions of flavors, colors, preservatives, and vitamins are typically added to improve the quality of food. These ingredients are often in a concentrated form, which must be accurately added to ensure consistency and avoid waste of the ingredient. The FMI valveless metering pumps provide the precision required to maintain a high level of quality; They are designed to provide flawless consistency and a long service life, making quality much easier to achieve.


  1. Flavor – Visual and taste consistency is incredibly important in the food industry. Food has to look appetizing to convince consumers to purchase it. For example, cherry Italian ice must always appear red. The FDA closely monitors food and color additives, including what foods it may be added to and the maximum amount that may be used. Food manufacturers must accurately measure small amounts of additives to ensure the desired effect is achieved without going over, and most importantly, this must be consistently applied to each batch. This can be achieved with our valveless metering pumps. They are engineered to be extremely precise, with accuracy held from microliters to the full flow range.


  1. Shelf-life – Many items are processed to improve shelf life, either with preservatives or with aseptic processing. Aseptic processing requires sterilizing food and the package to create a safe, ready-to-eat food. This process depends upon a metering pump to provide a continuous flow of the product through a holding tube. Our CeramPump® technology is specially designed for food and other OEM industry applications. It has only one move part, a rotating and reciprocation ceramic piston, providing an accurate, continuous flow. This means constancy and reliability.

Solving the Mystery of How our Valveless Piston Pumps Work

At Fluid Metering Inc., we’ve been on the forefront of metering pump and dispenser design for over half a century. Adding to our list of achievements is our patented CeramPump® line of valveless piston pumps represents true innovation in metering pump technology. The design is valveless because it utilizes one moving part to provide both the metering and valving functions. With a design as groundbreaking as this we get a lot of questions such as, “how does it work?” and “what makes it better than other pump technologies?” To answer these questions, we released a new video featuring a 3D animation of the metering and dosing action so customers can see exactly how our pump works and learn how it can benefit their application.

How It Works

The valveless design uses just one moving part to accomplish all fluid control tasks. It consists of a piston with simultaneous, synchronous rotating and reciprocating action. A flat is machined onto the piston, as it rotates within the flow the flat acts as the valve opening and closing the inlet and outlet ports of the pump. At the same time, the reciprocating action provides the pumping function. The metering flow rate is from 0-100% and is adjusted by setting the angle of the pump head relative to the drive. The adjustment varies the piston stroke length, and in turn, the volume pumped per stroke.

The internal components are composed of sapphire-hard ceramic which delivers a high level of dimensional stability. This means high precision dosing, extreme wear resistance, and chemically inert characteristics.

Benefits of a Valveless Pump

The unique technology of the valveless pump means that customers will receive a more accurate pump, with a longer service life, that won’t need to be recalibrated. Traditional metering systems utilize valves and many more moving parts that wear overtime, even during normal operation. This means that recalibration and system failure is a way of life. Users must keep spare parts on hand and track wear and calibration activities to ensure uninterrupted service.

Our valveless design has fewer moving parts which equal less wear, and less wear means less downtime. Because ceramic parts are more wear resistant than other materials, our pumps can last for millions of dispenses providing the same precision every time. CeramPump® metering pumps are ideal for R&D laboratory, instrumentation, industrial process, and environmental applications.

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.
