The CHEM-PRO M™ series metering pump from Blue-White Industries has the features and attributes industry pros have wanted, but couldn’t find in diaphragm metering pumps. These features include: NSF 61 listing — a must in municipal water systems; 200:1 turndown; a large, easy to read LCD screen that displays the pumps’ output rate; a 4-20mA output is standard on all models; a robust #316 stainless steel pump head cover for added strength; and a comprehensive three year warranty.
