The JAECO AGRI-PAK is a packed plunger metering pump with a streamlined design and rugged construction that provides low-cost, uninterrupted, trouble-free service for the continuous accurate metering of chemicals and solutions. This line of pumps has been optimized for agricultural applications. The positive displacement supplies a simple and virtually maintenance-free approach to accurate chemical feed. This metering pump is available in both simplex and duplex models and field-convertible from simplex to duplex. The capacity is manually adjustable, but only while pump is stopped, as a safety precaution and for tamper resistance. The capacity is easily automated using a variable-speed drive. JAECO AGRI-PAK FEATURES A low-cost, uninterrupted, trouble-free service for the continuous, accurate metering of chemicals and solutions. Available in simplex and duplex models, field convertible from simplex to duplex Positive displacement supplies a simple and virtually maintenance-free approach to accurate chemical feed. Pumps can run dry without pump failure. Rate of injection is manually adjustable, but only while pump is stopped, as a safety precaution and for tamper resistance. Rate of injection is adjustable for a turn-down ratio of 10:1. Accuracy of ± .5% at steady state. Single ball check valve, standard on both suction and discharge side of the pump, provides accurate metering and fast response. Because it is a true positive displacement pump, a safety relief valve on all closed loop systems is required to prevent possible over pressuring the discharge line. Duplex pumps can have different size pistons. Complete with single-phase or three-phase motor.
