These diaphragm pumps meet FDA contamination control requirements.  | Max Flow | 140 L/min (4.9 cfm) | | --- | --- | | Max Pressure | 2 psig (140 mbar rel) | |   Operating Voltage |   12 VDC | | Price Range | Call for Pricing | [DATA SHEET 3000 SERIES (PDF) ⟶](https://dynaflopumps.com/hubfs/3000%20Series%20-%20Dynaflo%20-%20Data%20Sheets.pdf?hsLang=en) [Request a Trial Pump](https://dynaflopumps.com/create-your-competitive-edge-dynaflo-inc?hsLang=en) ## Why customers love the 3000 Series Our customers tell us these pumps provide the only true smooth output flow on the market. ## Why you will love this pump ###### Patented smooth flow technology Single or dual-head diaphragm pumps - due to their "bicycle pump" nature of providing pulsatile flow - are usually not known for producing such smooth flow output. The 3000 Series is a multi-head diaphragm compressor with 12 mini diaphragm pumps in series, positioned radially on a central, single eccentric. Each pump goes through its usual cycle once per rotation, the same as single-head pumps. They are each 30 degrees apart from their neighbor to create a 12-point averaging effect on output flow. This symmetrical, balanced design eliminates pulsation and vibration issues while providing a constant torque load on the motor to mimic the smooth, natural breathing pattern of patients. ###### Efficient and long-lasting The 3000 Series diaphragm pump utilizes a low-profile, long-life brushless DC motor that operates over a wide range of speeds so your ventilator can precisely control the amount flow to patients and work reliably with prolonged use. We’ve also given careful attention to the profile of our diaphragms, so they yield high efficiency. Instead of a flat elastomeric part that would have to be stretched for each cycle, Dynaflo’s diaphragms are designed to flex by rolling. This reduces the work required by the motor and extends your ventilator’s lifespan. ###### Lightweight Despite close to three hundred parts that make up each compressor, the 3000 Series diaphragm pump is surprisingly light, weighing in at only 1.5 lbs (0.7 kg).  This makes it particularly attractive for battery-powered, portable ventilators used in critical care, transport, and military environments. ###### Built with precision Designed and built in the United States with medical-grade, precision materials for use in demanding environments.  Every diaphragm pump we build is focused on safe and reliable performance that meets or exceeds the requirements of the FDA for contamination control. ###### Meets transport standards The 3000 Series pumps meet the transport standards EN 794-3 and ISO 10651-3 for emergency and transport ventilators, EN 1789 for ambulances, EN 13718-1 and RTCA/DO-160G for aircraft, as well as IEC60601-1-12 for basic safety and essential performance. ###### Oil-free The 3000 Series diaphragm pumps are oil-free for maintenance-free operation. Being oil-less  means our diaphragm pumps operate without risk of contaminating the medium being pumped. When maintenance is necessary, replacement parts are readily available and easy to get to and replace.

We use this information to determine your product's proper flow rate, cycle time, power, and vacuum/pressure levels.  ###### Diaphragm pump evaluation We provide complimentary trial periods for pumps that meet your specifications so you can quickly test and evaluate how the pump will perform in your product. We then work together to determine if modifications need to be made to the pump's standard specifications to ensure it meets all your requirements, mounts quickly, and is easy to maintain. ###### Development, inspection, and testing If changes are required, Dynaflo's engineering will fine-tune the material, mechanical, and mounting options of the pump to fit the precise requirements of your product. We inspect and test 100% in line with your requests before sending your diaphragm pump for final testing in your products. Once all tests have passed, we ship your diaphragm pumps and spare parts. It is important to us to minimize the overall running costs of our diaphragm pumps, and we take this into account in the pricing of our pumps and replacement parts. ###### Follow-up and feedback Our partnership doesn't end once you have your pumps. After your products are in use, we will reach out to collect your feedback and evaluate how the diaphragm pumps are working for you. As the market changes and new needs develop, we respond with innovative, suitable solutions.
