CDS-John Blue

130 Years of Legacy Irrigation Pumps and Fertilizer Pumps Since 1886, farmers have trusted CDS‑John Blue pumps for accuracy, reliability, and value. That legacy lives on in our latest products—born of strong engineering, quality materials, and true American craftsmanship. Innovation runs through every line of our pumps and accessories for precise application, irrigation, and fertigation systems that consistently exceed expectations. We know a legacy is proven in the field—with equipment that’s “Guaranteed to Do the Job.”

Accessories, Equipment, and Systems for Ag Pumps With our patented Liquid Blockage Monitor System (LBMS), you can view and verify correct application flow on a display right in the tractor cab. LBMS works in tandem with the VisaGage II Flow Monitor. Combined with our enhanced Flow Divider and Next Generation Piston Pump, you get the most reliable fertilizer system on the market today. Other innovations—Variable Rate Hydraulic Drive Kits and the new Direct Hydraulic Drive Piston Pumps—deliver even better results in the field and continue to earn industry awards.

Beyond Liquid Fertilizer We didn’t stop at liquid application. CDS‑John Blue also offers anhydrous ammonia (NH3) application solutions, including Impellicone flow dividers and splitters that increase accuracy and reduce over‑application year after year. You asked—and we delivered—with the new NH3 VisaGage II Flow Monitor and an electronic Blockage Monitor System for in‑cab flow monitoring.
