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.

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.

Environmental Monitoring of Surface and Groundwater using Rhodamine Dye

As we prepare to showcase our metering pumps at Analytica, we wanted to share a common problem our pumps have solved.

Analytical sciences is an exact “quantitative” science which most often relies on precision fluid control of both samples and reagents to obtain the most accurate analysis.  One application where Fluid Metering’s valveless metering pumps have been very successful is in groundwater studies using rhodamine dye as a tracer chemical.  Though dosing and sampling procedures and data analysis methods vary with application, in general, the standard procedure in dye fluorometry hydrologic studies is to introduce a quantity of dye into a water body, and subsequently collect water samples over some spatial and temporal regime. These samples are then analyzed with a fluorometer for the concentration of the dye that is proportional to its fluorescence.

Dyes mimic the movement of water molecules. A measure of the movement of a dye (i.e., Rhodamine WT) will in effect be a measure of the movement of the water and, therefore, substances transported by the water in which it is introduced. Dispersion and mixing occur in all dimensions of the water body (Wilson, et. al. 1986). For example, in streams vertical mixing typically occurs first. Subsequently, and depending on current, channel configuration and stream characteristics, lateral mixing and longitudinal mixing follow. These phenomena are the subjects of interest to investigators employing dye fluorometry. For other bodies the sequence of mixing phenomena may vary, but the principle holds true nevertheless.

Fluid Metering’s QBG Low Current Metering Pumps are ideal for precision injection of rhodamine dye for surface, stream, and groundwater flow studies.  The three main reasons Fluid Metering’s QBG pumps are ideal for this application are as follows:

  1. Accuracy – As with any quantitative study, the results are only as accurate as the procedure and apparatus used.  FMI’s valveless design features only one moving part in fluid path, a sapphire-hard ceramic piston. This, as well as elimination of check valves from the pump design result in a metering pump having long term precision of 0.5%.
  2. Inert Internal Components – Using chemically inert ceramics and fluorocarbon wetted parts ensures that the pump will not skew results due to contamination contributed by the pump.
  3. Low Current Operation – The QBG consumes only 60 mA of power at 12VDC. Since, environmental studies are typically in remote locations, devices that run at low current will operate for extended periods of time on battery power.

At Fluid Metering we’re all about solving problems. With over 55 years of experience in providing dispensing and metering solutions we have worked with a variety of applications across several industries. Our metering pumps are also ideal for applications such as detecting chemical and physical properties of a substance such as blood chemistry instrumentation in the medical field as well as non-medical instrumentation for liquid and gas chromatography systems, pH monitors, and more.

To see how we can help you with your application be sure to visit us this week at Analytica in Munich, Germany. The trade show runs from April 1-4, 2014 and we’ll be located at Hall B2 Booth 338 showcasing our solutions for the pharmaceutical, chemical, food, plastics, and OEM industries.
