Liquid coloring made easier


Many of the processing difficulties inherent in the use of liquid-color concentrates are reportedly eliminated by a new automated, liquid-color management system. The Pump-in-a-Drum liquid-color system uses a specialized metering system and pump fully enclosed in a drum to deliver color in a completely sealed environment. Siphoning the colorant through sealed tubes, Pump-in-a-Drum also features automatic shutoffs to prevent leakage in and out of the drum. The drum?s lid has a hydraulic quick-connect fitting with an internal shutoff valve that restricts liquid flow when the pump is operating. In addition, the system?s tubes reportedly aren?t susceptible to the wear and tear experienced with peristaltic pumps. Pump-in-a-Drum accommodates two drums and automatically switches over to the full drum once one is emptied. An alarm is also triggered to alert users that one drum is empty. Liquid colorant can cost more per pound than pellet concentrates, but Riverdale says liquid systems offer more value and long-term savings since they carry higher pigment loads and can be used in smaller amounts.
