All CHEM-FEED® metering pumps feature Blue-White’s exclusive heavy duty cartridge valve head. The thoughtful design of this pump head begins with bullet cartridge valves constructed of tough PVDF plastic. Each valve has two ceramic ball checks and is double sealed with high grade Aﬂas O-rings. The double ball valve pump head design ensures enhanced priming capabilities, and it is exceptional for purging air and gas.
Peristaltic Injectors are well suited to metering chemicals that could foul heads with conventional check valves. Peristaltic pumps have rollers that compress the tube in progressive squeezing action. All FLEXFLO® Peristaltic Pumps are equipped with Blue-White’s exclusive patented Tube Failure Detection (TFD) System.
