HVS Drum Unloading Machine

The High Viscosity System (HVS) is engineered to simplify the unloading of 200L drums containing high-viscosity, paste-like and non-self-flowing substances. This versatile drum unloading machine is incredibly mobile and can empty a drum, even one filled with double-concentrated tomato paste, in under 2 minutes, showcasing it’s speed and efficiency. Designed for handling high viscosity liquids and hygienic applications, the HVS Drum unloading machine empties substances transported in barrels, such as:

Food and Beverage:

• Tomato pastes
• Caramels
• Fruit and vegetable concentrates
• Peanut butter
• Mayonnaise
• Nougat pastes
• Chocolate/Fudge
• Glycerine Oils

Cosmetic and Pharmaceuticals:

• Cosmetic and Pharma Vaseline’s
• Ointments
• Creams and Lotions
• Semi-solid waxes/paraffin
• Glycerine
• Oils
• Lip glosses
• Mascaras
• Facial cleansers

Being a piece of pneumatically powered equipment, the actuators within the HVS Drum raise and lower the pump, while the AODD pump works due to two diaphragms connected by a single diagram shaft. It is pushed back and forth by alternately pressurising the air chambers behind the shaft and using an automatically cycled air valve system to alternately pressurise the air chambers behind the diaphragms.

Take a look at our High-Viscosity Drum Unloading Systems in action in this dedicated video:  

• Achieve a flow rate of up to 400 l/min depending on the liquid properties and discharge pressures
• Safe, simple and easy to use and maintain
• Sealless construction with no rotating parts
• Significantly reduce processing times compared to manual emptying
• Removes up to 99% of the product from the drum
• Suitable for a variety of duties in Industrial and Hygienic installations (FDA, EN 10204 compliant)
• Hygienic surfaces with perfect cleanability made from polished steel
• Reduce waste and associated costs
• Lip Seal or Inflatable Seal options
• Optional back-up diaphragm system with rupture detection
• Flexible installation options – can even be used for direct container filling from palletised drums

For the longevity and reliability of your pump and system, we recommend having spare parts on hand, and based on the application and the severity of the operation, we offer two different spare part kits:

• KIT LIQ: Includes parts on pump wetted side
• KIT AIR: Includes parts on the pump air side

HVS Quattro: incorporates a Sanitary Air Operated Diaphragm Pump for Hygienic applications

HVS Flexi: incorporates a Hygienic Progressive Cavity Pump for Hygienic applications
