CHEM-FEED® Diaphragm Metering Pump

C-1500N Series Injectors feature Blue-White’s exclusive heavy-duty head with cartridge valves constructed of PVDF. Each valve has two ceramic checks and is double-sealed. The double ball valve design enhances priming and is exceptional for purging air and gas. The heavy-duty head is nearly maintenance-free, and the bottom and top valves are completely interchangeable for quick, easy, and economical servicing.

The C-1500N features a quick adjusting, high accuracy mechanical stroke length control.
