Specialty & Brass Gear Pumps

CDS-John Blue Specialty Pumps are positive displacement piston pumps that are designed for today's chemicals and accuracy. Their variable stroke length makes changing rates simple. The ground wheel drive design maintains a constant application rate as you speed up or slow down. Like all our pumps, CDS-John Blue quality extends right to the basic materials we use. Our CDS-John Blue Specialty Pumps are made from 316 stainless steel and silicon bronze materials, ideal for those extra hard to handle agricultural products.
