Request Information
This new guide helps users plan a chemical feed installation and specify the right chemical metering pump or complete chemical feed system for their application. "Sizing and Selecting Metering Pumps/Planning a Metering Pump Installation" defines the variables to be evaluated in specifying a metering pump or planning a complete chemical feed system. These include flow rate, discharge pressure and materials of construction. It also advises what to look for in the chemical to be pumped. Is it viscous? Is it a slurry? Does it release gas? Information is provided on the viscosities handled by standard metering pumps, as well as liquid ends and tubular diaphragm heads available for special applications.

Another factor covered in the guide is the environment in which the pump will operate. Is there freezing, or corrosion, to be dealt with? Also, what method of control will be used? Included is a discussion of manual versus automatic control of the metering pump flow rate, and which to use on motor-driven or electronic diaphragm pumps.

Guidance is provided on planning the entire metering pump installation from the day tank or other liquid source up to the injection point. This includes diagrams on flooded versus top mount suction and a layout detailing the various components (relief valve, pulsation dampener, backpressure valve, check valve) between the pump discharge and the injection quill. Advice is given on what to look for in selecting each component.
