Accuracy of flow can be maintained for many hours. Pump output is practically independent of variations in pressure. Vernier controls permit easy calibration and good duplication of desirable flow rates. Mate rial being moved never comes in contact with pump mechanism. Wavelike motion of steel fingers forces material through tygon tubing.
