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.

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.

Use these pumps to move lubricating oil, such as motor oil. Spout is removable and can be replaced with a garden hose.

All of these pumps have bonding and grounding wires, while some also have an internal flame arrester, to pump fuel, cleaning solvents, and lacquer thinners.

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.

Pump Repair Kits—Repair kits include components such as gaskets and pistons.

Made with PTFE components, these pumps stand up to aggressive chemicals our other drum pumps can't, such as hydrochloric acid, bleach, sodium hydroxide, and methyl ethyl ketone (MEK). A stopcock prevents fluid and vapor from leaking after use.

For low-effort dispensing, a lever handle maximizes output with each stroke. The handle delivers fluid on both the forward and backward strokes to quickly move drum contents. Lock the handle with a padlock (not included). Flow is reversible.

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.

Tap Kits—Remote tap kits extend your pump's reach for transferring liquid to tanks, mixers, and sprayers. They include a splash guard, a 6-ft. PVC tube, and hardware.

A nozzle and hose allow you to dispense directly into your container. The lever handle maximizes output with each stroke for low-effort dispensing. The handle delivers fluid on both the forward and backward strokes to quickly move drum contents. Lock the handle with a padlock (not included). Flow is reversible.

A lever handle delivers fluid on both the forward and backward strokes for faster dispensing than other drum pumps. The handle can be mounted with the knob above or below the pump body. Lock the handle with a padlock (not included).

These pumps have a _3/4" ID discharge hose for transfer applications and a vacuum breaker that drains the hose to prevent siphoning.

Since these pumps use suction to draw liquid out of your container, they continue dispensing once you get them started. They're often used with coolant and water.
