Inject chemicals into your water supply without using electricity—these pumps install directly in your pipeline and activate when water flows into the pump head. They provide consistent metering regardless of pressure and flow changes and have an adjustment dial for altering dosing concentration. Pumps are often used with bleach, cleaning solutions, and water-treatment chemicals. All are self-priming and create suction to draw liquid upward. Do not use with solids.

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.

Dispense precise amounts of fluid from a syringe. Commonly used in chemical and pharmaceutical research, fiber production, and equipment calibration, these pumps maintain a steady flow rate for accurate filling and measuring. Use the color touchscreen to set parameters such as flow rate, force, and volume; schedule start and stop times; and create and save custom operations. Pumps work with glass, plastic, and stainless steel syringes from 0.5 µl to 60 ml. Mount horizontally or vertically; the touchscreen rotates.
