Adjustable-Flow Easy-Stroke Drum Pumps for Water and Chemicals

304 Stainless

Steel Housing

These pumps have a selectable flow rate, so you can adjust flow for different dispensing applications. A lever handle maximizes output with each stroke for low-effort dispensing.

Whenever working with flammable liquids, always bond and ground your application for static control. For more information about bonding and grounding, see Sections 1910.106 and 1910.107 of the Federal OSHA Code or see bonding and grounding equipment.

Smooth-Flow Air-Powered Double Diaphragm Pumps

Also known as sprayer pumps, these provide a smooth, uniform flow for agricultural spraying, soap dispensing, and chemical transferring. They automatically turn on when you open the outlet valve. Pumps are self-priming, which means they create a suction force to draw liquid upward to fill the pump chamber. Do not run dry.
