North American Leading Asphalt Roofing Company

A leading American roofing shingle manufacturer’s corporate “reliability engineer” reached out to DESMI. He was looking for an alternative to the filled asphalt pumps that his company had used for years from another supplier. He had been going through the factory’s equipment to determine which products were the least reliable and costing the most money. DESMI proposed the proven HD201 ROTAN® asphalt pump, and the client agreed to a demanding trial. The goal was that if the pump could run for 12 months, then it was a success. The DESMI HD201B was installed in January 2019, and over one year and a half later, the pump is still operating at original speed. It is still performing just as it was January 2019 more than a year ago. It has proven to be an exceptionally successful trial.

ROTAN® pumps are made with a ”back pull out” system! This means that a pump, delivered on a base plate, with a spacer coupling, connecting gear or motor to the pump, can be serviced without breaking any pipe connections or moving the motor/gearbox. Just by taking out the spacer in the coupling, you have access to dismount the total rear end of the pump.
