single head adjustable pump

The Stenner Mixer is designed to fit the tank system or tanks and is typically utilized when injecting solutions that are difficult to keep in suspension.

Stenner with its versatile capabilities, the Classic Single Head Adjustable Output pump is a popular choice for water treatment solutions.

The Single Head Adjustable Output Pump is one of four types in Stenner's Classic Series and is an ideal choice for treating problem water. The pump can inject water treatment 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, Animal Health, 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.

How the Single Head Adjustable Output 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.
