GRI’s line of Bellows Metering Pumps were specifically designed for metering applications requiring low discharge pressures. Bellows pumps utilize GRI’s proven proprietary blend of polypropylene materials to provide an accurate and economical, long-lasting metering pump. A wide selection of valve and O-Ring elastomers produce chemical resistance pumps capable of handling both corrosive and non-corrosive fluids.
Bellows Metering Pumps operate on a positive displacement principle. Depending on the size and configuration of the bellows modules, these fluid pumps produce flow ranges from 3.9 to 3000 milliliters per minute. Based on the Bellows Metering model, both fixed flow and adjustable flow pumps are available with a maximum stroke to stroke repeatability of ± 0.5%.
Typical applications include Film and X-ray Processors, Silver Recovery Systems, Wafer and Silicon Chip Washers and Processors, Detergent Dispensers, Blood Analyzing Equipment, Industrial Floor Scrubbers, Thermo Therapy Equipment, Waste Removal Systems, and Wastewater and Water Treatment Systems.
