Chemical metering pumps can allow you to dispense chemicals reliably and accurately. Choose from diaphragm and peristaltic models that are available in several max. flow (gallons per day), max. pressure, voltage, max. viscosity, horsepower (HP), phase, and output flow rates suitable for many metering applications. Chemical metering pump systems feature proportional feed for treatment of well water systems with variable flow rates and a convenient panel-mount configuration. Chemical transfer magnetic drive pumps can handle liquids such as mild acids, mild alkalis, and saltwater. These caustic pumps are designed to isolate the pump mechanism from the motor to help eliminate seal-caused friction loss, wear, contamination, and leakage. Grainger has many chemical pump accessories including valves, and pump heads, to pump head rebuild kits, pump tubes, and chemical solution tanks. Our chemical metering pump repair parts can keep your chemical pumps running and help avoid breakdowns.
