Testimonials

Since the very first time we contacted Akkerman in 2006 they have been nothing but helpful! We did a RPO on a pilot tube system for a project and the rest is history. We have 3 pilot tube systems and other Akkerman equipment now and would not change a thing. They are a high-quality manufacturer, and they provide excellent after the sale support (to include supporting us on Akkerman equipment bought from other contractors) with in stock parts and technical assistance.
