Customer Testimonials
You've been there, you get it …I pass this along because it is precisely the type of customer service we appreciate and respect. Many don't understand the importance of getting us back on line quickly and we need to have an equipment vendor who understands the equipment they sell. You do understand how important it is to have us up and running… and you clearly understand your equipment. We all thank you for your professionalism. Finally, from your email back to David, it is also abundantly clear that you realize we are not Exxon Mobil or Chevron. We are a start-up in every sense of the word and at this point need an equipment supplier who realizes our concern over every dollar. You've been there, you get it, and for that, too, I thank you! When the time comes, I look forward to talking with you about another Dolphin purchase.
For the ongoing reservoir side centrifuge filtration you are looking for I would suggest you contact Sanjay at Dolphin Centrifuge. I have been dealing with Sanjay for over 15 years now and he is by far the best at what he does. Aside from the fact he can provide a custom solution for you at the best price, his service is excellent. He has even answered my call in the middle of the night before when he was in Japan on a startup.
Thank you! for your continued support. Both machines are ripping through the stream – good separation. We'll be calling you shortly for 2 more.. stay tuned.
By the way Jim (Kraft) is very good. He really knows his centrifuges and the process. I am so glad that we brought him in.
Dolphin Centrifuge did an excellent job of building our MOPX207 separator skid to build it as a compact setup with an easy plug and play operation. Everything that went into the unit as far as the automation from controls for the computer system is very user-friendly. It was very noticeable how far they go to make sure their Centrifuge builds are user-friendly through the computer system, giving the operator the ability only to type in few parameter settings such as % solids and GPM. Hands down, you could tell these guys were very experienced at running these units and processing through these units. They had excellent communication, and if we hit a hiccup along the way, they could clearly explain what was happening and how to correct it.

Why Customers Stay With Dolphin
The testimonials above share common themes: engineers who genuinely know the equipment, responsive support at unusual hours, transparent pricing that respects smaller budgets, and systems that just work. These are not marketing promises — they are observations from customers who bought equipment, put it into service, and came back for more.
Dolphin Centrifuge is not a used equipment dealer that happens to sell centrifuges on the side. Industrial centrifuges are all we do. That focus translates directly into deeper technical knowledge, better application guidance, and more reliable after-sale support than you will typically receive from a generalist equipment dealer. Learn more on our About Dolphin Centrifuge page.
Our free lifetime technical support — no subscription, no expiration — reflects our confidence in the equipment we build and our commitment to the customers who buy it. When you call us five years after your centrifuge ships with a question about bowl cleaning intervals or a troubleshooting puzzle, we pick up the phone.
