Dynaflo's modular design vacuum pumps and compressors offer a range of customization options and can often be fitted to suit the needs of your application. When an application requires a unique or exclusive design, however, Dynaflo's team of engineers can work with you from conception to production. Like our standard modular deisngs, Dynaflo custom-engineered pumps and compressors are backed by the same warranty and parts and services guarantee for the life of the product.


All design, engineering, and assembly are handled on-site; with Dynaflo you will get the individual attention your application needs, plus the benefits of one-stop outsourcing. Dynaflo provides individual designs and service for off-the-shelf prices: that's our guarantee.


When working on a custom pump or compressor design with Dynaflo, you get the benefit of individual service with the efficiency of an engineering process that is handled exclusively in-house. We guarantee a streamlined protocol that will benefit your application's production as well as performance. In addition to your custom design, we can easily adapt your product for additional uses with configuration options we offer on all Dynaflo vacuum pumps and compressors.  


Dynaflo's expertise in engineering design produces vacuum pumps and compressors that exceed the average performance of similar products. High flow, compact and virtually maintenance-free designs are Dynaflo's specialty.



Our team of engineers strive to ensure that Dynaflo OEM vacuum pumps and compressors offer state-of-the-art performance and design


Our vacuum pumps and compressors come standard with the following features.


Design Optimization

Dynaflo's application-specific design approach results in each pump's physical size and configuration being precisely matched to your performance requirements. Total design flexibility means that no pump is any larger than necessary, and that even the most difficult envelope restrictions can be satisfied


Component Specification

Every Dynaflo pump component is precision crafted to assure all performance requirements can be reliably met at a minimum of size, weight and cost. Dynaflo pumps routinely perform at levels usually associated with much larger and more costly devices.


Material Selection

Dynaflo pumps utilize lightweight alloys and composite thermoplastics wherever practical. This class of high-strength, light-weight engineering materials is used by Dynaflo for components traditionally made from heavy metal castings.


Design Details

Dynaflo's extensive use of composite thermoplastics allows for the introduction of design intricacies that would be economically prohibitive in traditional materials. This results in component parts designed from the ground up to be strong, light-weight and efficient.


Rolling Diaphragm Design 

Dynaflo's pump diaphragms move by bending rather that stretching the diaphragm material. This minimizing the force required to displace the diaphragm, and helps to maximize mechanical efficiency.


High Flow Valves

Dynaflo pumps utilize the highest capacity inlet and outlet valves possible. This minimizes pressure drops across the valves, and maximizes both flow capacity and pneumatic efficiency.


Ball Bearing Drive

Dynaflo pumps are available with ball bearing construction throughout. Without the frictional losses associated with sleeve or sliding bearings, Dynaflo pumps operate at the highest mechanical efficiency possible.


Low Friction Design

With no sliding pistons, valves or seals, and ball bearing construction throughout, Dynaflo diaphragm-type pumps can literally be built without wear components, providing both high efficiency and extremely long life.


Brushless Motor Commutation

Fitted with brushless drive motors, either DC or AC, Dynaflo pumps can be built without motor brushes to wear out or contaminate the environment with brush dust. Dynaflo pumps have been tested for tens of thousands of hours of continuous operation.



"Oil-less" means there is no risk of oil or other lubricants contaminating the medium being pumped. Many pumps utilize pistons or other friction-intensive components that need lubrication, risking possible contamination of the flow stream. Dynaflo's diaphragm vacuum pumps and compressors are free of any lubrication in contact with the flow path.

Qualification - Is Dynaflo right for you ?


After an initial consultation, we will respond with design concepts and budgetary cost estimates for product that suits your application. This is typically informal data to help confirm that Dynaflo can provide the product you need.


TIME: Typically less than a week after the discovery phase.

COST: There is no charge for the qualification process.


Proposal - What Dynaflo can do for you


Once we've confirmed that Dynaflo can serve your application, we will provide you with a Proposal and Statement of Work. This is a formal contract that outlines the work, cost, and performance you can rely on from Dynaflo.


TIME: Typically within 2 weeks of initial contact, depending on the nature of the project and the extent of custom content.

COST: There is no charge for a Dynaflo proposal


Design & Prototype - Working Together


This phase is entirely dependent upon the project, and is done in the spirit of concurrent engineering between the customer and Dynaflo. We plan and carry out Design Reviews to ensure 100% satisfaction. In most cases, we work closely with design engineers to co-develop new products. We work within agreed confidentiality guidelines, and will provide a non-disclosure/ confidentiality agreement as appropriate.


TIME: Project dependent

COST: Project dependent


Production and After-Sale Support - We stand behind our products


We work with you to prepare a Manufacturing Agreement, usually in the form of a contract, with quantities, prices, and delivery schedules. We also agree on how to support the units after sale, with plans for return/repair, spare parts, and warranty.


Dynaflo stands behind its custom and modular vacuum pumps and compressors, and guarantees a 100%, 120-day warranty on defection materials or components for all modular and custom designs. We offer parts and services for the lifetime of the product.


Simple, Thorough, and Easy! Working with Dynaflo is a direct and reliable process, with exceptional outcomes and support.
