The Riverdale Gravimetric Stand (RGS), provided and maintained by Riverdale Global, prevents the handling complications and workplace mess associated with liquid color. The RGS sealed delivery system, exclusively manufactured by Maguire Products, requires no equipment investment for Riverdale Global customers.

In the RGS, the pump is permanently installed inside a standard-size drum, mounted on a self-calibrating loss-in-weight scale, which stays sealed from when it leaves Riverdale Global to its return for refill from customers.  During processing, color is metered through a sealed tubing assembly, with automatic shutoffs preventing spillage. RGS software can easily be networked for central control and monitoring.
