Packed-Plunger Metering (Injection) Pumps 10.7-190 GPH Flow Rate Pressures up to 520 PSIG • 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 FEATURES & BENEFITS • 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. • Additional motor options available. • All units come epoxy painted, completely assembled on a base plate and have been fully tested. SULFURIC ACID/INFURIC APPLICATIONS • For those special applications of applying Sulfuric Acid or Infuric, the recommended material of construction is Alloy 20. Consult factory for Alloy 20 material. MOTOR OPTIONS • Single or Three Phase • 12V DC • Variable Speed Motor Drive • V-Belt • Gasoline • Pressure relief valves • Calibration columns • Back pressure valves • Pulsation dampeners 316 Stainless Steel - Standard Alloy 20 - Optional Neoprene - Standard PTFE - Optional Viton

JAECOAGRI-PAK™ MODELS MODEL # MAXIMUM CAPACITY (1) SIMPLEX GPH 1. Capacities with 1/3 HP motor at 1725 rpm. 2. Flow rates are based on water at maximum rated pressure. These are the most common size agricultural pumps. Other sizes and materials available. Model #M20-172-S2N2 will require a 3/4 HP motor. Determine type of Jaeco pump to use. Select appropriate model from capacity/pressure chart. Or, contact your Jaeco representative with the following information: fluid name, concentration and compatibility; fluid properties – viscosity, temperature, vapor pressure, particle matter size and percent;...
