Description

Accurate chemical injection for agricultural applications

JAECO AGRI PAK™ packed plunger irrigation injection pumps are built for reliable, continuous chemical injection in demanding agricultural systems. Designed for accurate feed of chemigation and fertigation solutions, these positive displacement pumps deliver dependable performance. The AGRI-PAK 112 is a duplex injection pump with flow rates from 21.4 to 62 gallons per hour and pressures up to 520 PSIG. The duplex model allows for the pumping of two different fertilizers or additives at half capacity or one injection at full capacity.

Pump Details:

• Plunger Diameter = 3/4″
• Liquid End = 316 Stainless Steel
• Packing Material  = Neoprene
• Motor = Single Phase 1/3 HP, TEFC, 1725 RPM
• Maximum Capacity = 21.4 GPH, 520 PSI / 35.6 GPH, 350 PSI / 62.0 GPH, 200 PSI

Key features and benefits

• Accurate positive displacement metering
  The AGRI-PAK uses positive displacement pumping to provide a simple, consistent approach to chemical feed. This helps maintain accurate injection rates for agricultural treatment programs.
• ± 0.5 percent steady state accuracy
  Precise metering supports dependable chemical application and helps reduce overfeeding, underfeeding, and chemical waste.
• Runs dry without pump failure
  The pump can run dry without failure, helping protect equipment during low tank levels, interrupted supply, or changing field conditions.
• 10:1 turndown ratio
  A wide adjustment range gives operators flexibility when application requirements change across systems, crops, or treatment schedules.
• Manual injection rate adjustment
  The injection rate is manually adjustable while the pump is stopped. This adds a practical layer of operator safety and helps resist tampering.
• Fast response check valve design
  Single-ball check valves on both the suction and discharge sides ensure accurate metering and fast response during operation.
• Simplex and duplex flexibility
  AGRI-PAK pumps are available in simplex and duplex models. Units are field convertible from simplex to duplex, and duplex pumps can be configured with different piston sizes for added flow flexibility.
• Factory assembled and tested
  Each unit is epoxy-painted, fully assembled on a base plate, and tested before shipment, helping simplify installation and startup.

Important system note

Because the AGRI PAK is a true positive displacement pump, a safety relief valve is required on all closed-loop systems to help prevent possible overpressurization of the discharge line.
