High Pressure Brass Pumps

"Golden" Diaphragm Pumps

The CDS-John Blue High Pressure "Golden" Brass Pumps are an ideal fit for orchard sprayers and flexible enough for any applications requiring high pressures. All pumping surfaces that come into contact with the pumped liquid are made from brass and the diaphragm washers are 316 stainless steel. The brass parts include the heads and manifolds, which make the CDS-John Blue Golden Pump fully protected against corrosion from commonly used products. The manifolds, which are positioned exterior to the crankcase, ensure that the pumps can be run safely and also help to extend the life of the pump. The ease of maintaining the Golden Pump is unmatched in the industry, due to the simplicity of servicing the valves.
