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/pressure 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, electrical 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.
