Versatile Capabilities

The Single Head Adjustable Output pump is one of the varieties in the Classic Series. The pump is identified by 45MJ or 85MJ in the item number prefix.

The single head adjustable pump is a reliable solution for a wide range of water treatment needs. It effectively handles applications such as pH control, disinfection, corrosion and scale prevention, and the oxidation of iron, manganese, or hydrogen sulfide for removal through filtration. These pumps are commonly used across industries like water conditioning, industrial processes, wastewater treatment, and cooling towers.

Beyond traditional uses, this versatile pump also supports specialized applications such as Legionella prevention in cooling systems, sprinkler head cleaning in irrigation and horticulture, and plating bath treatment in metal finishing. In addition, it is widely trusted in the commercial pool industry for sanitizing pool water and protecting equipment performance.

Features

  • Interchangeable pump heads and tubes to convert one model to another without having to purchase a new pump.
  • Tube replacement without tools with the patented QuickPro® pump head.
  • Three detachable components; the motor, feed rate control and the pump head that can be separated without tools.

How the Single Head Adjustable Pump Works

The output is determined by three factors; the RPM of the motor gears, the setting on the feed rate control and the pump tube size. The feed rate control has an external dial ring that is labeled L to 10 offering an adjustable output range from 5% to 100% in 2.5% increments.
