In 1986 River City Enterprises, Division of Staffco, Inc., Peoria IL, developed a unique piston system to store and dispense viscous materials up to 500,000 centipoise. The non-pressure 400 gallon piston bins gave customers a system for the storage, handling and delivery of low, medium and high viscosity products. Rugged, lightweight, and durable, the piston bin provided a simple solution for handling viscous products and quickly became popular in many industries.
The piston system developed by River City is unique. It consists of a sealed, closed loop patented piston system and a plastic tank for storage. As the piston moves down, the inflatable piston seal wipes the inside tank wall, making the bin virtually 100% efficient. The piston also acts as a barrier to protect high quality, expensive materials from air, moisture, dirt, and other contamination. A positive displacement pump is used to fill and discharge the material through the 3” bottom valve and quick coupler.

Eight years ago, River City needed to find another bin supplier. After checking with several companies, they found that Assmann Corporation, Garrett, IN, was the best choice to design the bin they needed to use with the piston system. Since 1996, Assmann has been supplying River City with reusable 400 gallon polyethylene storage tanks. Assmann engineered the bins specifically for River City.
Commenting on the Assmann plastic storage tanks, Stewart Boal, President of River City, “said, “We chose Assmann tanks because they are high quality. The tanks stand up well and do the job. We also wanted an ISO certified manufacturer. Assmann is a 9001 ISO certified company.”
