Where We Began

How Did We Get Here?

Founded in 2008, Pump Dynamics started as the pet project of a lifelong pump person moving out west. William Cocks used his 30 years of experience in the field to start a small company in Washougal, Washington. Nowadays, Pump Dynamics spans the entire West Coast with further plans to spread and grow. 

With offices in Washington, Oregon, and Arizona we have the space and the expertise to handle your equipment, big or small. For onsite troubleshooting and repairs, we have an arsenal of skills ready to go – Call us for pump and motor rebuilds and repair, shaft machining, laser alignment, metallurgical analysis, and machine health monitoring. The list goes on!

Our Values and Promises

How We Run our Business

We believe in continuous innovation, constantly improving designs and improving efficiency. We value delivering all these things while reducing operating costs for our customer. We understand that performance is not only in the product, but in the service we provide. Our team is both qualified and efficient, providing timely and friendly service to all of our clients.

Three Core Values
Drive All That We Do


We believe safety is no accident. It's easy to spot a dangerous situation and act instinctively. We approach any situation with a reasoned plan, based on rigorous training and situational awareness, to ensure the safety of our employees.


Our commitment to quality is in everything we do. It starts with the highest quality products and people and ends with our guarantee to stand behind the parts and services we offer. Our guarantee to you does not end when we walk away, but when you're satisfied.


We believe real service cannot be bought or even measured, but must be earned through tireless commitment to sincerity and integrity. We bring this attitude with us on every job, no matter how big or small.
