Fixed-Flow-Rate Metering Pumps for Chemicals
Also known as peristaltic pumps and tubing pumps, these maintain a fixed flow rate. Pumps are self-priming, which means they create a suction force to draw liquid upward and fill the pump chamber. Mount them up to 25 feet above your liquid source. All can run dry. Do not use with solids.
Pumps with Tygon 2375 lining resist harsh substances such as isopropyl alcohol and sodium chloride.
Pumps with Viton® fluoroelastomer tubing withstand oil such as gasoline and hydraulic oil.

Flanged Metering Pumps for Chemicals

Commonly used in mining, wastewater treatment, and other systems that require large-diameter hose, these pumps have flanged hose connections. They are compatible with chemicals such as cleaning fluids, acid-washing solutions, and detergents. Pumps have a reverse switch that allows flow in either direction. They are self-priming and create suction to draw liquid upward. They can run dry.
