Patented micro diaphragm pumps are available for OEM solutions. We can work with you to customize our pumps to your specific needs. The Formulatrix micro diaphragm pumps have many advantages over traditional pumps.
Can be produced in high quantity at low-cost for disposable applications where a sterile pump may be needed.
Large arrays of pumps are easily made. Optional independent channel control is available of each pump in the array.
Active valves allow for bi-directional pumping. Diaphragm volumes from nanoliters to mililiters can be produced.
|Applications:||Low volume dispensing -- Disposable pumps for sterile applications -- Parallel dispensing of a single or many liquids|
At the core of our liquid handling technology is a patented microfluidic valve cluster that can meter and dispense discrete volumes of liquid using positive displacement. This valve cluster can fill and dispense as fast as 20 times per second (exact speed depends on specific product). This proven technology is both incredibly precise and viscosity independent. Below is a Flash demonstration of the entire process.
Many diaphragm pumps can be controlled by a single set of valves to allow large parallel arrays as represented in the diagram above
Pumping can be reversed by altering the sequence of valves and diaphragm actuation. If desired valves can also be used to close off fluid lines or opened to allow free flow.
The diaphragms move between hard surfaces on the top and bottom to ensure consistent volumes.
Pressure and vacuum supplied by remote valves allows for a low cost liquid path.
Our high quality pump solutions are not always going to be the best solution for a given application. Please refer to the pros and cons of our pumps to decide if they may be right for you. If you have more questions about specific applications for these pumps, please don't hesitate to contact sales to find out more information.
Micropump with two diaphragm volumes, integrated input gasket and nozzle. This is an example of a low cost disposable pump.
Diaphragms can be produced in a range of sizes from nanoliter to milliliters.
