Liquid Metering Pumps

Liquid metering pumps are commonly used to introduce liquids into a reactor or vessel at elevated pressures on a continuous basis. 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.   All pumps can be operated from their faceplates and all except the 2312E can also be remotely controlled with a 0-10VDC analog signal, such as from the Model 4871 Process Controller.  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.
