chemical injection pump used in chemigation

When looking for a chemical injection pump, you may come across terms like “metering pump” and wonder if they’re the same thing. While people sometimes use these two terms interchangeably, chemical injection and metering pumps have some key differences.

JAECO offers a variety of high-quality metering pumps for chemical injection. Whether these pumps will work well depends on your application’s flow rate, pressure, viscosity, and other requirements. 

Read on for an overview of chemical injection pumps vs. metering pumps and discover how JAECO metering pumps can meet your chemical injection needs.

Chemical Injection Pumps vs. Metering Pumps

Chemical injection pumps inject small amounts of chemicals like corrosion inhibitors or biocides into a process stream or storage tank. They can handle hazardous fluids at high pressures of up to 10,000 psi.

Metering pumps are more versatile and can be used across many industries to accurately dose chemicals, fluids, or additives. They operate at lower pressures than chemical injection pumps. At JAECO, our metering pumps have a maximum pressure delivery of up to 2000 psi.

While all chemical injection pumps are metering pumps, only some metering pumps can be used for chemical injection. The suitability depends on your specific flow rates, pressure requirements, and the chemicals pumped.

JAECO Metering Pumps for Chemical Injection

JAECO offers a range of durable, high-precision metering pumps that may be suitable for chemical injection depending on your requirements:

Diaphragm Metering Pumps

We engineered our FRAM diaphragm pumps for accurate, leak-proof fluid handling. This innovative design makes them highly adaptable for chemical injection. These pumps utilize a hydraulically actuated diaphragm that minimizes wear for long-term reliability.

The FRAM line is available in both simplex and duplex configurations. The duplex models provide redundancy and/or extra capacity to keep your process running smoothly. The pumps are also field-convertible between simplex and duplex.

With turn-down ratios up to 10:1 and accuracy within 0.5%, these versatile pumps can meet a wide range of chemical injection flow rates and dosing needs. The stroke rate can be easily automated using a variable speed drive.

Other key features include:

  • Leak-proof operation with hydraulic diaphragm actuation
  • Top-mounted fill ports for quick access
  • Heavy-duty gear reducer for smooth, reliable performance
  • Adjustable stroke length for variable flow rates

JAECO’s FRAM diaphragm pumps are up to the task of accurate, reliable chemical injection over long periods.


Agricultural Diaphragm Pumps

The AGRI-FRAM line from JAECO is ideal for agricultural applications like irrigation, fertigation, and chemigation. The durable, hydraulically actuated diaphragm design provides precise dosing for water treatment chemicals, fertilizers, and other agricultural fluids.

Like our standard FRAM pumps, the AGRI-FRAM models utilize separate hydraulic and gear chambers to optimize the operation and reduce wear. This design allows for accurate, continuous chemical injection even in challenging agricultural environments.

Some key features include:

  • Durable hydraulic diaphragm actuation
  • Heavy-duty gearbox for smooth power transmission
  • Manual stroke adjustment from 0-100%
  • Turn down ratio of 10:1
  • Accuracy of ±0.5%

Whether you need to inject fertilizer into irrigation water, apply pesticides, or meter pH-adjusting chemicals into drainage systems, the AGRI-FRAM has you covered. Its robust design stands up to harsh agricultural conditions for long-lasting performance.


Plunger Metering Pumps

JAECO’s PAK plunger pumps are an efficient metering pump option for chemical injection applications that demand robust, reliable operation. These pumps utilize packed plungers and a simple stroke adjustment system to deliver precise injection.

The PAK pumps are available in simplex and duplex configurations. The duplex models provide redundancy and/or extra capacity that keeps your process moving in case of any issues. The pump’s highly adjustable stroke length lets you manually control flow rates during operation. This enables a turn-down ratio of up to 10:1 to adapt to changing conditions.

Key features:

  • Compact, streamlined design
  • Rugged cast iron construction
  • Adjustable stroke length up to 10:1 turn-down ratio
  • We can automate it with a variable-speed drive
  • Standard ball check valves for accurate metering
  • Simple maintenance with oil bath lubrication

For industrial chemical injection that needs to run 24/7, PAK plunger pumps offer an efficient, trouble-free solution. Their durable build and manually adjustable flow control make them ideal for critical applications.


Agricultural Plunger Pumps

JAECO AGRI-PAK plunger pumps can meet the unique demands of agricultural chemical injection applications. This robust pump offers accurate, consistent chemical metering for water treatment, fertigation, chemigation, and more.

The AGRI-PAK models combine a simple plunger design with manual stroke adjustment for variable flow control between 10-100% of maximum rating. This enables turn-down ratios up to 10:1 to adapt to changing agricultural conditions.

Other key features:

  • Rugged cast iron construction
  • Low-cost, trouble-free operation
  • Ability to run dry without damage
  • Compact, streamlined footprint
  • Accuracy of ±0.5%

This agricultural workhorse provides reliable chemical dosing for irrigation water, drainage systems, hydroponics, and more. For affordable accuracy that you can count on, the AGRI-PAK gets the job done right.


High-Flo Plunger Pumps

When higher flow chemical injection is needed, JAECO’s HI-FLO plunger pumps are an excellent solution. With maximum flows of up to 19 GPH and pressures of up to 250 PSI, these heavy-duty pumps can handle demanding metering applications.

Like our PAK pumps, the HI-FLO line uses packed plungers and check valves to deliver smooth, precise injection. The plunger and head assembly allow for quick maintenance – no need to break pipe connections.

Key features:

  • Heavy-duty construction for rugged reliability
  • Flow rates up to 341GPH (Simplex) or 682 GPH (Duplex)
  • Pressures up to 7,200 PSI
  • Quick access to the plunger and head internals
  • Compact footprint to save space
  • Turn-down ratio up to 10:1

With higher flows and pressures than our standard PAK pumps, JAECO’s HI-FLO line is ideal for industrial processes with significant chemical injection demands. Their simple, durable design provides long-term, trouble-free operation.
