Manufactured By the Team You Already Trust
For more than four decades, Precise Mechanical has been an industry leader in repairing, rebuilding, and optimizing Nash® liquid ring vacuum pumps used across pulp & paper, power generation, chemical processing, mining, and general industrial manufacturing.
Now, we’ve taken that expertise a step further — by designing and manufacturing our own line of fully compatible replacement pumps engineered to meet or exceed the performance of original Nash® models.
Every pump we build reflects our hands-on experience servicing thousands of units in the field — we know what fails, why it fails, and how to make it better.
Our new manufactured Nash-replacement pumps deliver reliable performance, drop-in interchangeability, and lifetime service support from the same experts who’ve kept these systems running for over 40 years.
