The CDS-John Blue DP-90.1-GRI Diaphragm Pump is engineered for medium-pressure applications, delivering a maximum flow rate of 10.6 gallons per minute (GPM) at 650 revolutions per minute (RPM) and capable of handling pressures up to 580 pounds per square inch (PSI). This pump features a three-diaphragm design constructed from chemical-resistant elastomers, ensuring durability and longevity even when used with aggressive chemicals. The housing is made of anodized aluminum, providing resistance against corrosion. The DP-90.1-GRI model includes a gearbox suitable for 3.5 to 5 horsepower (HP) engines and comes equipped with the SC-1132-2 pressure regulator, which offers two outlets and a shut-off valve for enhanced control. The pump is designed for versatility, with mounting options that accommodate sprayers with a power take-off (PTO) drive or can be equipped with gasoline, electric, or hydraulic motors. Its compact and lightweight design makes it suitable for a wide range of low-pressure applications, including gardening, liquid transfer, and powering small sprayers and washers. The pump's components are plastic-coated to withstand corrosion from most industrial and agricultural chemicals, and all moving parts are completely submerged in oil, increasing reliability and reducing maintenance needs.
