DUS Drum Unloading System

The Murzan DUS (Drum Unloading System) is the ultimate drum unloading solution for emptying the most viscous materials from various types of containers. The containers can be made of metal, plastic, or fiber.

The DUS will reduce your total unloading time and labor requirements.

The DUS is made up of 100% Stainless Steel materials, including the frame and cylinders. The unit is provided with a NEMA 4X control panel that contains all the pneumatic components.


The Murzan DUS Drum Unloading System utilizes a T-316L stainless steel, sanitary Double-Suction Murzan Diaphragm pump. This pump is mounted on a stainless steel follower plate and is fitted with a food-grade scraper ring, which scrapes the inside of the drum or container as it is emptied. A frame constructed of T-304 stainless steel supports the pump and base. The system is equipped with two air cylinders, which lift the pump and base out of the drum or container once it is empty. Sanitary casters are installed for portability to allow use in different unloading areas. A NEMA 4X stainless steel control panel is supplied with this unit.


The operation of the system is very simple. With the container in place, the compressed air in the bottom of the air cylinders is released, and the pump is lowered into the container. The pump and base plate will float on the surface of the product. As the product is pumped out of the container, the pump and base plate travel down into the drum wiping the wall of the drum. Once the container is empty, air is directed back into the bottom of the air cylinders and the pump is lifted out.


Capacities up to 60 gallons per minute may be achieved, depending on the specific gravity, viscosity, consistency of the product, and the total dynamic head (TDH) of the application.
