Thanks to their space- and energy-saving design, these micropumps are a smart and affordable choice for industries demanding both advanced functionality and cost savings. Versatile and durable, they set a new standard for affordability. How our micropump is assembled The micropumps in Bartels’ BP7 series are compact and robust double diaphragm pumps. At their core, they operate with two piezo actuators, which drive the diaphragms to enable fluid movement. These actuators are electrically connected via a flexible cable, ensuring efficient energy transfer. All components are housed in a sturdy, space-saving casing, providing durability and ease of integration into various systems. Functional principle: How piezo electric micropumps work The functional principle of Bartels micropumps is based on a piezoelectric diaphragm in combination with passive check valves. A piezo ceramic mounted on a coated brass membrane is deformed when voltage is applied. By the resulting down stroke, the medium is being displaced out of the pump chamber below. The check valves on both sides of the pump chamber define the flow direction. Applications: Discover the possibilities of our micropump Even in the most demanding applications, our BP7 micropumps prove their versatility. Whether in: - medical technology - analytical technology - mechanical engineering - space research - many other applications – our micropumps set new standards. Our BP7 micropumps are truly tiny, but they have what it takes. With extremely small dimensions and low weight, they are already equipped for many fields of application. But that is not all. These little powerhouses offer an impressive particle tolerance of up to 40 µm and are extremely temperature-resistant. This makes them a real all-rounder for a wide variety of applications. Variable flow rate adjustment guarantees a wide range of possible applications. Technical Specification - Typ. Dynamic Range Flow Rate (Water): 0 – 9000 µl/min - Typ.
