Designed to fit into small equipment, these pumps have miniature gears and a subfractional horsepower motor for low-flow applications. Pumps are gravity fed and require an elevated liquid source to fully fill the pump before turning on. Do not run dry or use with solids.

Note: If flow control is needed, place valves or reducers on the discharge side; never restrict the inlet of a pump with a valve or reducer.

Mount these pumps in any position, even upside down. Pumps have a subfractional horsepower motor rated for intermittent use (return to room temperature before restarting). Also known as diaphragm pumps, they are for use in low-flow spraying, draining, and washdown applications. They are self-priming, which means they create a suction force to draw liquid upward. Pumps can run dry and do not require an initial fill, so they’re a good choice for applications without a constant flow of liquid. Do not use with solids.

Battery-operated pumps operate on a 12-volt battery. They are commonly used with agricultural sprayers and washers.

Pumps with a pressure switch automatically shut off the pump at the maximum pressure.

Rated for continuous use, this pump is often used to move caustics such as antifreeze and salt water. Mount it in any position, even upside down. Also known as a diaphragm pump, it is typically used for low-flow spraying, draining, and washdown applications. Pump has a pressure switch that automatically shuts off the pump at the maximum pressure. It is self-priming, which means it creates a suction force to draw liquid upward. Pump can run dry and does not require an initial fill, so it’s a good choice for applications without a constant flow of liquid. Do not use with solids.

Commonly called rotary vane pumps, these are designed to pump water at high pressures in low-flow applications. Motor is open dripproof (ODP) for use in clean, dry, and well-ventilated environments. They have a built-in bypass relief valve to prevent pressure buildup. Pumps are gravity fed and require an elevated liquid source to fully fill the pump before turning on. Do not run dry or use with solids.

Note: If flow control is needed, place valves or reducers on the discharge side; never restrict the inlet of a pump with a valve or reducer.

These pumps have a bronze housing and gears for use with water. Select your own motor to tailor them to your application. Use a NEMA 56C frame electric motor with a coupling and belt/pulley drive. Also known as gear pumps, they produce a smooth flow of liquid for water delivery. All are self-priming, which means they create a suction force to draw liquid upward and fill the pump chamber. Do not use with solids.

Note: Pumps must be filled with liquid before use. They need a constant flow of liquid and cannot run dry.

With a 316 stainless steel housing and stainless steel gears, these pumps are often used to dispense chemicals such as ethylene glycol, isopropyl alcohol, and nitric acid. Use an electric motor with a coupling and belt/pulley drive. Also known as gear pumps, they produce a smooth flow of liquid. All are self-priming, which means they create a suction force to draw liquid upward and fill the pump chamber. Do not use with solids.

A cast iron housing and steel gears allow these pumps to be used to dispense oil and fuel such as hydraulic oil and diesel fuel. Select your own motor to tailor them to your application. Use an air or electric motor with a coupling and belt/pulley drive. Also known as gear pumps, they produce a smooth flow of liquid for applications such as engine lubrication. All are self-priming, which means they create a suction force to draw liquid upward and fill the pump chamber. Do not use with solids.

Note: Pumps must be filled with liquid before use. They need a constant flow of liquid and cannot run dry.

Commonly called rotary vane pumps, they have a built-in bypass relief valve to prevent pressure buildup. Attach an electric motor with a speed reducer or a belt pulley to alter the pump speed. Use a NEMA 56C frame motor. Pumps are gravity fed and require an elevated liquid source to fully fill the pump before turning on. Do not run dry or use with solids. They meet NSF/ANSI 61 safety standards for use with drinking water systems.

Pumps with a 303 stainless steel housing are more corrosion resistant than pumps with a brass housing.

Also known as plunger pumps, these can provide pressures up to 3,000 psi. Use them for washdowns, drain jetting, and other pressurized water-spraying applications. Connect them directly to an electric motor to alter the pump speed. Pumps are gravity fed and require an elevated liquid source to fully fill the pump before turning on. Do not run dry or use with solids.

Use these pumps to move lubricating oil such as hydraulic and motor oil. Also known as flexible impeller pumps, they create a suction force that can draw liquid upward to fill the pump chamber when your liquid source is below the pump. The impeller resists clogging and wear. Select a spark-free air motor for hazardous environments or attach an electric motor with a speed reducer or a belt pulley to alter the pump speed.

Repair kits (sold separately) include components such as impellers, O-rings, and seal lips.

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.

This pump has a totally enclosed nonventilated (TENV) motor that is cooled by the liquid being pumped. Also known as a flexible impeller pump, it creates a suction force that can draw liquid upward to fill the pump chamber when your liquid source is below the pump. Mount up to 6 feet above your liquid source. Pump can pass solids up to 1/4" in diameter without clogging, so there’s no need to filter sediment and debris. A handle makes it convenient for on-the-go removal of bilge water, waste oil, and spills. Pump can also be used to cool marine engines and drain liquid from holding tanks.

Note: Pump must be filled with liquid before use. It needs a constant flow of liquid and cannot run dry.

Convenient to keep in your toolkit for on-site cleanup, these pumps attach to your drill for small liquid extraction jobs, as well as draining water from clogged sinks and emptying tanks. Pumps are self-priming, which means they create a suction force to draw liquid upward. Do not use with solids.

Note: Pumps must be filled with liquid before use. They need a constant flow of liquid and cannot run dry.

Also known as gear pumps, these have few moving parts so they're less prone to wear than other hydraulic pumps. Combine with an electric motor to generate flow in a hydraulic system. To mount to a NEMA C-face motor, use a Pump-to-Motor Mount (sold separately).

UN/UNF (SAE Straight) thread connections have straight threads and are also known as O-ring Boss fittings.
