Liquid Metering Pumps

Liquid metering pumps are the more appropriate way to introduce liquids into a reactor or vessel at elevated pressures on a continuous basis as opposed to the batch process for which the liquid filling pipettes are commonly used. A wide variety of pumps are available to meet various pressure, flow, and control requirements. The pumps listed here cover some of the more common pressure and flow requirements associated with Parr reactors and pressure vessels. The pumps described under these catalog numbers include an inlet filter, a reverse-flow check valve and the outlet tubing to the reactor. Special pumps can be furnished to meet requirements outside the range of these pumps.
