Mini Bellows Metering Pumps Product Overview Mini Bellows Metering Pumps are ideal for low flow, low pressure metering applications. The pump is constructed entirely of plastic and uses GRI’s time-proven bellows technology to provide an accurate chemically-resistant metering pump with a long life, at an economical price. Mini Bellows Metering Pump Operation: The Mini Bellows Metering Pumps operate on a positive displacement principle. The rotation of the motor shaft is transmitted into an up and down linear motion through an adjustable concentric crank mechanism. This motion provides a continuous...

Flow Adjustment: The ½” and ¾” bellows modules can be adjusted to 20% of maximum stroke length, while 1”, 1-1/2” and 2” bellows modules can be adjusted down to 10% of maximum stroke. Note: Best priming and metering accuracy occurs when the stroke length is 50% or greater. Standard Crank — Adjustment cannot be made while pump is operating. An adjusting screw changes the stroke length of an eccentric crank. Compact Bellows Metering Pump Specifications: Average Repeatability — From stroke-to-stroke ± 0.75% Flow Rates — Range to 270 ml/min, Tandem models range to 432 ml/min Max Discharge Pressure...
