G-Chem™ DC & AC Operated Pumps

Entry level Chemical Pumps


The G-Chem series pumps are ideal for chemical injection applications. Built from the same quality standards as current Graco chemical injection pumps, the G-Chem pump has the lowest out-of-pocket cost of Graco electric chemical injection pumps, is easy to operate and far exceed the performance of similar pumps of its class. The DC operated pumps are also offered in solar system packages that come with a 100 watt solar panel and the new Harrier® EZ controller as the standard product offering.
