J Series Ratio:Feeder® Injection Systems

J System


J Series Ratio:Feeder® Injector Systems can inject almost any liquid chemical into a water line at a set ratio. Most common uses include fertilizer injection, acid injection for pH stabilization, chlorination, and sanitization.

All J Series Injectors can be configured to pump multiple chemicals or solutions at different ratios. Systems can be configured to work with flows ranging from 1/4 gallon per minute to 10,000 gallons per minute. Common injection rates range from 1:100 to 1:10,000. Injectors require at least 30 psi to operate with a maximum of 125psi or 100psi depending on which blend tank is utilized. Controllers can be powered using 120VAC or 12VDC.

J Series Injectors can be purchased as complete assembled units which fit most common applications or as individual components sized especially for your specific application.

About the J Series Injector

The J Series Injector is made up of 5 separate components. Click on the menu to the left for more information on these individual components.

  • J Series Controller - Connects to the water meter and pilot valve/manifold. It measures the water flow using the water meter then turns the pilot valve on and off to stroke the pump heads at the proper rate to maintain the set ratio.
  • Water Meter - Used by J controller to measure water flow. Many different models are available which can measure flows from 1/4 GPM up to 10,000 GPM.
  • Manifold/Pilot Valve - Pump Heads are mounted to the manifold. The Pilot Valve, which is controlled by the J Controller, provides water pressure to the pump heads to make them pump.
  • Pump Heads - Pump Heads are what actually pump the chemicals. Many different models and sizes a available to handle almost any liquid and feed ratio.
  • Blend Tank - Ensures the chemical injected into the water line is blended uniformly ensuring even distribution and allowing for accurate measurements to be made.

Features and Benefits

Proportional Feed

Every Anderson Injection System uses proportional feed to maintain the same feed ratio or PPM across the entire flow range of the system.

Positive Displacement

Unlike competing designs, Andereson Injectors utilize positive displacement diaphragm pumps which ensures injection rates will not degrade over time. Injectors with sliding o-ring seals lose acccuracy as seals become worn and lead to inconsistant injection rates.

Chemical Resistance

All Anderson Injectors are fitted with EPDM, Viton or Teflon diaphragms allowing almost any chemical to be injected.

No Acid Dolution Required

Acid can be directly injected using our A Series TeflonĀ® pump heads. This eliminates the need to dilute acid so handling dangerous chemicals can be avoided.

Multiple Pump Heads Available

Incompatible solutions can be injected separately by using multiple pump heads. Pump heads can be added to accomodate expansion projects and flow increases.

Wide Flow Range

Precision multijet watermeters allow injectors to work across a wide range of water flows and do not require a filter

Long Warranty

All Anderson Injectors come with a 15 month warranty because we are proud to stand behind our products

Sizing a System

Save time and money and ensure correct installation with one of our Complete Assembled J Series Ratio:Feeder® Injector Systems. These units ship setup for most common applications with flows up to 160 GPM.

The Ratio:Feeder® Sizing Calculator will help specify a proper system based on the required feed ratio and maximum water flow of an application.

The Feedratio Finder, located on the same page, will calculate the feed ratio of an existing system based on the number of pumpers, dial settings and gallons per stroke setting from the J Controller.
