An aluminum enclosure around the motor provides protection in dusty and dirty environments. 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.

Also known as gear pumps, these produce a smooth flow of liquid for applications such as cooling engines, powering hydraulic equipment, and extracting liquid from holding tanks. Pumps are self-priming after you fill the pump chamber with liquid. As liquid in the chamber is expelled, a suction force is created which allows the pump to draw liquid upward. Do not use with solids. Pumps can be used in dusty, dirty, and damp environments.

Pumps that cannot be sold to Canada are restricted by local energy efficiency requirements.

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

A high-horsepower motor moves oil with a viscosity similar to SAE 60 motor oil. Also known as gear pumps, these produce a smooth flow of liquid to lubricate equipment and blend oils. Motor is open dripproof (ODP) for use in clean, dry, and well-ventilated environments. 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. Products cannot be sold outside North America due to restrictions.

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.

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.

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 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.

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.

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.

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.
