The new Hibar H series rotary valve precision dispensing pumps are ideally suitable for higher viscosity applications in food, cosmetic, technical and pharmaceutical industries. The ceramic rotary valve design ensures easy handling of liquids with up to 100,000 cps viscosities and including particulates. It can maintain dispensing accuracies of ±1/2% or better with positive cut-off and no drip without readjustment or recalibration. This hibar pump has precise dispense volume and speed control via adjustment of the built-in micrometers. Wear resistant ceramic rotary valve handles high viscosity fluids with particulates up to 100,000 cps.
