First controlled volume pump of its kind, the Milroyal D combines industrial pump reliability with laboratory pump accuracy. • Reproducible accuracy: flow rates are accurately repeatable within 1 % . Positive stroke return insures accurately controlled volume on every stroke. Micrometer control adjustment. You can adjust the stroke while the pump is running, ideal for checking on variations in flow rates. • Industrial reliability:
totally enclosed, all moving parts run in oil, patented polar crank design for minimum moving parts, complete range of construction materials for a variety of requirements. You'll like the Milroyal D's reliability . . . and its versatility.
When your laboratory or pilot plant application calls for delivering very small amounts of liquids with critical accuracy and reliability, the new Milroyal will fill the bill.
