2000 SERIES custom MICRO GAS DIAPHRAGM PUMPS

Meet the highest performing micro pump

The 2000 Series micro diaphragm pumps are ideal for products that require high vacuum, portability, a high torque motor in a small package, and can start back up under full vacuum. 

These micro pumps are used in suction-based prosthetics, drug delivery systems, cooling supercomputers, and aerospace applications where safe, reliable operation is essential.

Need something unique? Every micro pump can be fully customized to meet your specific needs.

Power & Flow 0.7 lpm/W
Max Flow 1.2 l/min (0.04 cfm)
Max Vacuum ~914 mbar (27 inHg)
Max Pressure 2 bar (30 psi)
Price Range $150-$200*
*Prices are typical for brush DC motors. Final pricing depends on the motor, volume, and customization features.

Why customers love the 2000 Series

These micro diaphragm pumps reach high vacuum quickly, start back up under load, and run for hours.

Why you will love this micro pump

We specialize in creating reliable miniature diaphragm pumps for the medical industry. Our 2000 Series mini diaphragm pumps are ideal for products like partial prosthetics, which require starting under load. They do this using a high torque motor and a lightweight, compact design that’s built to last and start again without fail.

The 2000 Series mini diaphragm pump is designed to draw under 1 Watt at full vacuum. This power efficiency makes it ideal for any product that works off a relatively small battery and does not require much flow.

The 2000 Series offers 1.5 lpm of flow but also 30 PSI pressure and about 27 in of Hg of vacuum, making it one of the highest performing pumps of its size and type. It is also able to reach ~914 mbar (27 Hg) in a few seconds — making it ideal for small volume applications.

The 2000 Series diaphragm pump utilizes a low-profile, long-life brushless DC motor that operates over a wide range of speeds to work reliably with prolonged use.  Brush DC motor options are also available. 

Designed and built in the United States with high-quality, precision materials and a strong focus on safe, reliable performance. 

Dynaflo uses high-quality materials for the valve, diaphragm, and bearings—and a powerful, high torque motor to maximize the life of your battery-powered products in any environment.

Given that the bulk of the cost of the 2000 Series mini diaphragm pump is in the motor and is often used in harsh conditions, it is essential to be able to refurbish the pump while re-using the motor. To date, thousands of pumps have been updated and refreshed with new heads/valves and put back into service.

Building the perfect product together

Dynaflo, Inc. understands the importance of getting your products to market quickly. We provide skillful and confidential guidance throughout all phases of diaphragm pump development to create pumps that seamlessly integrate into your products and provide you with added value.

We work with your engineers and product managers to discuss the current market requirements your product must meet and the features that will delight your customers. We use this information to determine your product's proper flow rate, cycle time, power, and vacuum levels. 

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 - for free. 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 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.

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.

How the 2000 series is used in prosthetics

The diaphragm pump is the heart of prosthetic devices. It needs to reach a high vacuum within seconds, be able to start back under load, run on a small battery for hours, and fit into a tiny space.  Given the potentially harsh conditions associated with creating vacuum suction near the human body, it is also essential to be able to refurbish the pump while re-using the motor.  This is what makes the 2000 series perfect for prosthetics.
