High-Pressure Air-Powered Drum Pumps for Oil
Transfer lubricating oil such as hydraulic and motor oil with these pumps. They handle nearly twice the amount of pressure as other air-powered drum pumps to move high-viscosity liquids. Install an air line filter/lubricator to ensure efficiency and reduce wear on the pump.

Selectable-Flow-Rate Easy-Stroke Drum Pumps for Water and Chemicals
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.

Drum Pumps for Water and Coolant
A 316 stainless steel housing makes these pumps resistant to coolants such as ethylene glycol.
Repair kits include a gasket, a packing gland, a piston, a piston washer, and a push-on nut.
Nondrip Drum Pumps for Water and Chemicals
Eliminate leaks and waste with a faucet-style nondrip nozzle that quickly starts and stops flow. Pressurize your container with a few pumps of the plunger handle, and use the one-touch nozzle to manage flow. Hold down the nozzle for intermittent dispensing, open the nozzle fully for continuous flow, and close the nozzle to stop flow entirely.
Remote tap kits extend your pump's reach for transferring liquid to tanks, mixers, and sprayers.
Deep-Reach Suction Pumps for Fuel
Remove liquid from hard-to-reach areas with a long, flexible intake tube that extends into deep and hard-to-access tanks.
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.

Air-Powered Constant-Flow-Rate Pumps
Commonly called piston pumps, these are often used in high-pressure applications, such as hydrostatic testing of pipelines, tanks, and valves. Flow and outlet liquid pressure can be controlled by varying the air pressure. To calculate discharge liquid pressure, multiply the air pressure by the ratio shown in the table. Pumps are self-priming, which means they create a suction force to draw liquid upward to fill the pump chamber.
Note: Pumps must be filled with liquid before use. They need a constant flow of liquid and cannot run dry.
