This popular unit is ideal for multiple-building livestock and animal production facilities.


Dosmatic® SuperDos® mid-high flow, water-driven proportional injectors are a low-cost alternative to traditional electric technology. Unlike traditional electric pumps, the SuperDos® Injectors eliminate the need for electricity and can operate in remote areas.

They are easy to install and maintain, making them ideal for mid-high-flow injection applications.


  • Precisse additive injection — proportional positive displacement ensures that just the right amount of chemical is injected each and every time regardless of pressure and flow
  • Safe and cost effective — patented one-way mixing chamber gasket prevents chemical contact with motor piston
  • Durable body construction — the engineered proprietary composite material withstands severe weather, the chemicals used for injection, and higher operating pressures
  • New mixing chamber design ensures a more complete mixing of water and injected chemicals before leaving the unit
  • Existing connections for a remote discharge kit
  • Standard NPT inlet and outlets eliminate the need for a separate connections kits
  • Same three lower end service parts exchange between SuperDos® and Advantage models

    Replace Often

    Review by on Nov 14, 2016

    I like the SuperDos products, when they work. I've replaced 3 out of 4 in less than 3 years. They are not high volume usage. QC Supply is very friendly and helpful, I just wish the Dosmatic systems lasted longer. I'm using Fertilizer, Calcium, and Sulfuric Acid in these three units. Very accurate until they fade out. Spent too much money on replacement parts that never fix the problem and they are very costly. Searching for replacements that can be fixed, not replaced.

    Product worked exactly as advertised. A simple way to calculate the amount of fertilizer to be used would be most helpful.
    Installation very easy.
