Dosing Pump GRI’s new Dosing Pumps are ideal for low flow, low pressure metering applications where a fixed flow rate is required. The Dosing Pumps are constructed entirely of plastic and use GRI’s time-proven bellows technology to provide a durable and accurate chemically resistant metering pump. When pumping water in laboratory test conditions, pumps rate at +/- 1%, stroke to stroke. As with all of GRI pumps, the Dosing Pumps are highly OEM customizable. A variety of configurations are available to meet many different system requirements.
