About Zaxis:

Located in the heart of Salt Lake City, Utah we have maintained  a culture of innovation and success.  Still a privately owned company we continue to engineer the world’s finest leak testing and precision pumping technologies that are used by household name companies around the world.  We are excited about our growth and the amazing people who have helped us along the way. Subscribe to our newsletter to be the first to know what new technologies we are coming up with next. 

We came from humble beginnings. We were literally working out of a garage. But our little garage company has grown into an industry leader. That small company heritage is something we take pride in. We try to act as small as we can when it comes to our customers. We’re not interested in the sell-and-forget business. We want to deliver precision products to exceptional customers and build lasting relationships.

Since our humble beginnings, we have come a long way. In the Fall of 2014, we expanded into a 20,000+ SQFT facility to manage our future growth.  We are excited to innovate new technologies with the growing Zaxis force and we look forward to meeting you soon.  Thank you for being loyal to our company.  We hope that you find all of your solutions here with us and if not, we hope to provide them for you in the near future. 

We specialize in: Leak Detection and Dispensing 

Zaxis Metering Pumps

The Metering Pump is a controlled volume, positive displacement pump, which will accurately transfer a predetermined volume of fluid (liquid, gas, or slurry) at a specified amount or rate into a process or system.

It is defined by function, rather than by technology.

  • Positive Displacement –  multiples of a fixed volume.

  • Accurate and Repeatable  flow rates within 1%

  • Adjustable volume control is typically inherent in design.

  • Traditionally reciprocating designs, although rotary configurations increasingly applied.

  • Ideally, capable of handling a wide range of liquids, including corrosives, abrasives, viscous, toxic . . .

  • Capable of generating sufficient pressure to permit injection of liquids into processes.

Zais Leak Detection

A leak test is used to determine if an object, product, or system functions within a specified leak limit. Leaks occur when gas or liquid flow through an object via an imperfection or manufacturing defect such as holes, cracks, weak seals, etc. Leaks always flow from higher pressure to lower pressure; leak testers use pressure to generate and monitor that flow.

Other Leak Test Types Include:


  • Bubble/Submersion – This test simply putts pressure on the part, then dunks the part under water and looks for bubbles. This is a very common test

  • Hard Vacuum (Helium) – A part is charged with helium and then placed in a chamber. The Chamber has a vacuum pulled on it. A sensor in the chamber then detects any helium leaving the part and entering the chamber.  Helium is used because of the molecule size; helium gets out of smaller holes than air or nitrogen can.

  • Helium Accumulation – Helium is light, so it rises. This method puts the part under helium pressure and then captures the escaping helium in an umbrella shaped cone as it rises.

  • Helium Sniff – Similar to Helium Accumulation but the operator uses a wand to sniff the part and find where the helium is leaking out of the part.

  • Helium Spray – Vacuum is pulled on the part through a tester equipped with a helium sniffer. Helium is then sprayed around the part. Any air leaking into the part is picked up by the helium sniffer inside the tester.

  • Tracer Gas – This is another name for helium testing where other gases, such as hydrogen, are used.  Smaller gas molecules are used to find smaller leaks.

  • Ultrasonic – This method relies on higher-pressure air creating a sound that is picked up with a high sensitivity microphone.  Imagine the air creates a hiss that is detected by its frequency.
