Aluminum Proportional Mixers for Coolant and Soluble Oil

Use this mixer to dilute coolants and soluble oils with water. It dispenses solution directly from your drum in a measured ratio. Attach your water line to the inlet and set your desired mixing ratio with the regulator knob. The water line connection has a quarter-turn shutoff valve.

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.
