Electric Powered Chemical Metering Pumps


Low pressure chemical metering pumps for anti-scaling/anti-foaming

Metering Pump Low Flow Model

Low-Flow Models 17, 30, 45 GPD

Metering Pump High Flow Model

High-Flow 150 GPD Model

Our chemical metering pumps are suitable for dispensing chemicals for a variety of anti-scaling and anti-foaming applications. These pumps provide precise and adjustable delivery of anti-scale/anti-foam agents. Graco chemical metering/injection pumps deliver flow rates from 17 to 150 gallons per day and operate in -40° F to 175°F (-40°C to 79°C) temperatures.

Typical pump feed point is in the E-Z Tray inlet piping, ahead of the stripper. Turbulent tray action quickly ensures complete mixing on the top tray.
