The NORMco rental fleet has been assembled from what we feel are the very best diesel engines and centrifugal pumps available mounted on a NORMco custom- fabricated trailer. The engines in our fleet are tier 2 & 3 design which means less down time, less maintenance, and higher performance standards for our customer’s rental dollar. In order to assure the very best performance of our equipment, NORMco provides maintenance services on all our rental units every 250 hours of usage…and most importantly… this service charge is included in our rental rates at no additional cost to the customer.
