Agricultural Injection Metering Pumps

Jaeco AgriPak™ Packed Plunger Chemigation Metering (Injection) Pumps

Features/Benefits

• Streamlined design and rigid construction provide low-cost, uninterrupted, trouble-free service for the continuous accurate metering of chemicals and solutions.
• 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.
• Available with or without motor.
• All units come epoxy painted, completely assembled on a base plate and have been fully tested.
• For higher pressures and capacities see Jaeco Hi-Flo description on back.

Materials of Construction

Seals: Neoprene - Standard
PTFE or Viton® - Optional
