Design pulse-free ventilators that match patients' natural breathing patterns
Provide high performance, pulse-free ventilation to respiratory patients in demanding EMS, military, and medical transport environments. Dynaflo’s smooth flow radial diaphragm pumps provide high performance, low pressure, and the only real smooth output flow on the market so your ventilator can carefully control air flow to patients.
Match patients' natural breathing patterns
The patented 12-head radial design responds quickly to electrical/command inputs to provide ultra-smooth airflow at a pressure below 1-2 psi so your ventilator can deliver air that matches a patient's natural breathing patterns. This helps medical professionals feel more confident about their ability to ventilate patients properly and they spend less time on monitoring.
Precisely control air flow
An efficient, brushless DC motor operates over a wide range of speeds so you can precisely control the amount of flow your ventilator delivers to suit patients who are large, small, or everything in between.
Use in demanding environments
Dynaflo’s high-quality pumps are built in the United States with high quality materials to power critical care, transport, and military ventilators to treat patients in any environment and at any altitude. They can operate in a wide range of temperatures -40 to 120°F (-40°C to 50°C) and enable high to low flows to adjust to different atmospheric pressures.
In contrast to vane-driven ventilator pumps, the diaphragm pump is less sensitive to air density for performance, and is thus more suitable for use at higher altitudes.
Operate longer on a single battery
When lives are on the line, time is of the essence. And when you're working with a portable mechanical ventilator, efficiency is critical. Our diaphragm pumps use an efficient, long-life brushless DC motor and a unique multi-head radial-12 pump design. The symmetrical, balanced pumps deliver a near-constant torque load to the motor—allowing portable ventilators to operate much more efficiently than they would with uneven single and dual-head pump designs.
Keep it light and easy to move
Ensure medical professionals can easily move your mechanical ventilators from place to place. Despite having nearly 300 components, the 3000 Series diaphragm compressor weighs only 1.5 lbs (0.7 kg), ensuring it doesn't add significant weight to your ventilators.
The Best Pump for Mechanical Ventilators
Dynaflo's 3000 Series diaphragm pump is designed specifically for mechanical ventilators. The pump’s twelve mini radial pump heads are optimized to provide uniform, high flow at low pressure. They provide a truly smooth stream of air from a durable, lightweight body so ventilators can match the natural breathing patterns of patients.
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.
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.
Despite close to 300 parts that make up each compressor, the 3000 Series is surprisingly light, weighing in at only 1.5 pounds (0.7 kg). This makes it particularly attractive for battery-powered, portable ventilators used in critical care, transport, and military environments.
Whether you're in a hospital, an ambulance, or an aircraft, the last thing you want to think about is whether your equipment will fail you when lives are on the line. That's why Dynaflo pumps are built in the United States with medical-grade materials and designed specifically for use in demanding environments. Every pump we build is focused on safe and reliable performance that meets or exceeds the requirements of the FDA for contamination control.
Our diaphragm compressor 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.
Dynaflo’s diaphragm compressor pumps are oil-free for maintenance-free operation. Being oil-less also 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.

Building the Perfect Ventilator Together
Dynaflo, Inc. understands the importance of getting your mechanical ventilators to market quickly. We provide skillful and confidential guidance throughout all phases of diaphragm pump development to create pumps that seamlessly integrate into your ventilators and provide you with added value.
We work with your engineers and product managers to discuss the current market requirements your mechanical ventilator must meet and features that will delight your customers. We use this information to determine your ventilator’s proper flow rate, cycle time, power, and compression levels.
We provide free trial periods for pumps that meet your specifications so you can quickly test and evaluate how the pump will perform in your ventilator. 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.
If changes are required, Dynaflo's engineering team will fine-tune the performance, flow, and mechanical options of the pump to fit the precise requirements of your ventilator. If your requirements are truly unique, we will create a completely new, customized diaphragm pump just for you.
We inspect and test 100% in line with your requests before sending your diaphragm pump for final testing in your ventilator.
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.
Our partnership doesn't end once you have your pumps. After your ventilators are in use, we will reach out to collect your feedback and evaluate how your pumps are working. As the market changes and new needs develop, we respond with innovative, suitable solutions.
