In a time when companies wish to streamline costs

DESMI can help provide a clear solution of what is available today which could improve system reliability. Even better, DESMI helps its customers find and use pump features that not only improve reliability but shorten the downtime between failures.


The biggest features on DESMI’s HD ROTAN® asphalt and bitumen pumps is their modular design with a true back pull-out feature.

The back pull-out feature allows the whole rear rotating assembly of the pump to be pulled and serviced without touching the pipework or driver.


With the back pull-out design, no alignment is required after servicing. This means that you will never have to move the casing and never move the drive equipment. This way, you can get your pump back up and running quickly; it’s a huge feature and a huge saving.
