Ezi-Action Drum and Pail Pumps promote an easy way to dispense fluid out of your container. Delivering on the up-and-down stroke, the pumps can handle both drums and pails containing of liquid with high viscosity (up to 8000 cps).
They accommodate different kinds of liquids, ranging from lubricants, oil, industrial chemicals, diesel, cleaning chemicals, mild solvents, strong acids and alkalis. They can also handle food-related material since they are made from 100% FDA-compliant polypropylene and polyethylene.
Ezi-Action pumps are also easy to install and manage. They fit containers from 5 to 55 gallon and are designed to sit on the base of the containers so there would not be any leftover waste in the containers if full drain is applied.
This is the only pump that has one-year warranty in the industry. It is safe to dispense chemicals with high volume dispense at low pressure and there is a cap-on strap that prevents accidental dispense when not in use.
