The CDS-John Blue DP-90.1 Medium-Pressure Diaphragm Pump is engineered for agricultural and industrial applications, including horticulture, lawn care, nurseries, car washes, air blast orchards/vineyards, and poultry houses. Its versatile design allows for mounting on sprayers with PTO drives or equipping with gasoline, electric, or hydraulic motors. The pump features a three-diaphragm configuration, anodized aluminum fluid ends, and stainless steel check valves, ensuring durability and resistance to harsh chemicals and abrasion. All moving parts are submerged in oil, enhancing reliability, and the chemical-resistant elastomer diaphragms extend the pump's lifespan even with aggressive chemicals. Key specifications include a maximum flow rate of 9.0 GPM at 550 RPM, a maximum pressure of 580 PSI, and a maximum speed of 650 RPM. The pump operates at a maximum temperature of 140°F and weighs 17 lbs. It is designed for use with a 1-inch suction hose and a 1/2-inch NPT discharge hose. The recommended lubricating oil is 30 SAE. Optional models, such as the DP-90.1-GRI, include additional features like a gearbox for 3.5 and 5 HP engines and a pressure regulator with two outlets and a shut-off valve. Accessories include spray guns and lances, pressure regulators, and gearboxes for various engine sizes. The pump is suitable for various mounting options, including PTO, gasoline engine, hydraulic motor, or electric motor drives.
