We Hold Ourselves to a Higher Standard

Values are easier to stand by when you’ve made them a 40-year habit. Here’s what you can expect from MHV:

Do It Right

We believe doing something right the first time simply has more staying power. We use high-quality parts, adhere to strict tolerances, and follow strict processes to ensure you get more life out of our new and remanufactured vacuum pumps.

Follow Protocols

Extending the life of vacuum pumps doesn’t happen by accident. We’ve spent the past few decades developing processes and systems that ensure every pump we work on is at least built to OEM specification, or better.

Built Relationships

We don’t just have customers; we have lifelong relationships. We take the time to get to know those who buy from us – understanding their processes, providing training, answering questions, and striving for them to win.

Always Listen

We are experts. We know to listen to our clients and seek to understand their concerns, issues, and goals to make sure we recommend the right option.

Respect Our Team

We treat our employees with respect, choosing to invest in them, trust them, and empower them to do their best work.

Adapt When Appropriate

We have systems and procedures for a reason, but we are agile in our approach. We work with our clients and adapt to their needs, ensuring any adjustment we make protects the quality, safety, and longevity of their vacuum pump.
