Water Aspirator Jet Pumps

Pick up chemical spills and remove liquids in vacuum filtering systems—these pumps create suction to draw up liquids and gases as water flows through them. They’re made of HDPE and polyethylene, so they won’t break down when exposed to highly corrosive chemicals and acids. The suction end has a barbed tube connector, which attaches to your vacuum tubing. The connector stays attached to your vacuum tubing and connects to the pump when you’re ready to use it again. These pumps also have an internal check valve to prevent backflow.

Inline Water-Powered Metering Syringe Pumps for Chemicals

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.

Water-Powered Backup Sump Pumps for Water

Don’t let a power outage cause flooding. Powered by water flow in your supply line, this pump works as a backup to your primary sump pump. Use with debris-free water. Intake has a foot valve to prevent debris from entering your line. The water inlet has _3/4 NPT female threads and comes with a push-to-connect fitting for _3/4" ID tubing, so you can make either connection. The float switch is wired to the pump.
