METERING INJECTION PUMPS

Metering pumps and what is chemigation?

Chemigation is the addition of fertilizers or chemicals to your irrigation water to help your crops grow. Studies have shown chemigation is the most economical and accurate way to apply these products to your fields. In addition, it eliminates extra tractor passes, expensive equipment, and can be done whenever you want it to be.

What can you apply?

Almost any liquid including fertilizers, pesticides, herbicides, wetting agents, and water conditioners. Certain materials may need special handling, so check the label.

What kind of irrigation system is needed?

The system type does not matter. It can be pivot, drip, sub-surface, tape, pipe, laterals sprinkler, or open ditch.

What does chemigation require?

It requires a holding tank for the liquid being applied, hose fittings, couplings, and a filter, plus a metering pump for accurate and reliable product application.

What is a metering (Injection) pump?

The metering (injection) pump is the most important part of the system because it controls how much of the applied product is being added into the irrigation water. With a metering pump the injection rate per acre irrigated remains constant even if the flow rate or pressure of the irrigation water varies. The size of the pump is dependent upon the amount of product you need to apply.

 

 
   

 

 

JAECOAGRI-FRAM™ Hydraulically-Actuated Diaphragm Metering (Injection) Pumps

FEATURES & BENEFITS

  • Separate chambers for hydraulic fluid and gear lubricant make possible the use of the best medium for hydraulic diaphragm pulsing and the best medium for gear lubrication. The results are better pump performance and longer pump life.
  • Pumps can run dry without pump failure.
  • Patented, heavy-duty gear reducer system for superior performance.
  • Hydraulically-actuated diaphragm minimizes diaphragm fatigue.
  • Built-in hydraulic relief valve protects the pump.
  • Rate of injection is manually adjustable while pump is running or idle.
  • Rate of injection is adjustable for a turn-down ratio of 10:1.
  • Accuracy of ± .5% at steady state.
  • Easy-to-read stroke length adjustment dial.
  • No plunger seals to leak or replace.
  • Single-ball check valve, standard on both suction and discharge side of the pump, provides accurate metering and fast response.
  • 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.

MOTOR OPTIONS

  • Single or Three Phase
  • 12V DC
  • Variable Speed Motor Drive
  • V-Belt
  • Gasoline

ACCESSORIES

  • Pressure-relief valves
  • Calibration columns
  • Back-pressure valves
  • Pulsation dampeners

SULFURIC ACID/INFURIC APPLICATIONS

  • For those special applications of applying sulfuric acid or infuric, the recommended materials of construction are Alloy 20 or PVC.
  • Specially designed for accurate, completely leak-proof metering of difficult-to-handle liquids.
  • Available in simplex and duplex.
  • 6.9-56 GPH Flow Rate Pressures up to 1,000 PSIG.

JAECOAGRI-PAK™ Packed-Plunger Metering (Injection) Pumps

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.

  • Pulsation dampeners

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.
  • 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.
  • 10.7-190 GPH Flow Rate Pressures up to 520 PSIG.

JAECOHI-FLO™ Packed Plunger Metering Pumps

FEATURES & BENEFITS

  • Provides a simple and virtually maintenance-free approach to accurate chemical feed.
  • Stroke rate easily automated using variable-speed drive.
  • Capacity is manually adjustable, but only while pump is idle, as a safety precaution and for tamper resistance.
  • Stroke length is 0 to 100 percent adjustable for a turn-down ratio of 10:1.
  • Available with motor or as bare pump.
  • Single-ball check valve, standard on both suction and discharge side of the pump, provides accurate metering and fast response. Valve ball turns with fluid flow, constantly presenting a new face to the seat, and is therefore self-cleaning.
  • 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.
  • Integral lantern ring for packing lubricant may be used for internal purging when handling crystallized, corrosive or other hazardous liquids.
  • Packing adjustment-screwed gland nut ensures even take-up and fewer packing problems.
  • Models 324, 332 and 340 have a clamped column, suction and discharge check valve assembly that can be easily cleaned, inspected or replaced without breaking pipe connections.
  • Accuracy of ± .5% at steady state.
  • All units come epoxy painted, completely assembled on a base plate, and have been fully tested.
