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 is an ideal choice for treating problem water, it can inject solutions for pH control or to oxidize iron, hydrogen sulfide or manganese for removal by filtration. Disinfection, pH control or adjustment, corrosion and scale control and oxidation are common water treatment applications found in markets such as Water Conditioning, Industrial Process, Water and Wastewater, and Cooling Towers.
The versatility of the product expands into other markets as well, such as Legionella prevention in Cooling Towers, sprinkler head cleaning in Irrigation and Horticulture and plating bath treatment in the Metal Finishing industry. The pumps are widely popular in the commercial pool industry for sanitizing swimming pool water or maintaining the equipment.

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.
