Food grade drum pumps for the Food, Beverage & Cosmetics industry

  • Up to 99% evacuation rate
  • Inflatable seal for optimal performance
  • Flange connections for easy cleaning
  • Fits most bins, drums and containers
  • Available with Piston Pump and Air Operated Double Diaphragm Pump options

How do the unloading systems work?

The drum unloading systems have fast and easy operation. Once the bin, drum or container is placed below the unloader, the ram plate and pump is lowered into the container, just above the product. When the pumping starts the product is moved out of the container and the plate with inflatable seal travels down into the container, scraping product from the sides of the container. After the container is emptied the plate and pump can get lifted out by simply switching a button.

Drum Unloading System

Advantages of the SaniForce Drum Unloading Systems

  • Up to 99% evacuation rate which voids the need (completely or almost completely) for an operator to scrape the wall and dump leftover material into the feeder. This reduces operator time.
  • No more labor intensive work for the operator as the operator doesn’t has to use force in order to get all product out of the container. The operator doesn’t even have to be with the product when it’s working.
  • Overall improved ergonomic work environment. Operators don’t have to use stairs or overstretch to get the product out of the container.
  • No need to dump big amounts of materials (200/400 kg) into hopper devices which can result in damaged machinery.
  • Clean and easy operation as product will be guided all the way.

Other technologies the Unloading Systems could replace

The drum unloading systems can replace Lift-and-Dump systems. Lift-and-Dump systems are used to transfer big amounts of materials stored in containers. During the lift-and-dump process containers are lifted to variable heights through open air, than the container is tilted so the product can fall out, which brings several risks for workers and their surroundings.  After every dump you still have to scrape the walls of the container manually which is work and time intensive.

Also there is a bigger chance of injuries on the work floor as operators often have to hang over stairs to reach the remaining product in the container. Likewise overstretching is one of the main injuries when working with a lift and dump system. Another risk is the big amount of product falling from a height which can impact or even damage the hopper system.
