Constant-Flow-Rate Pumps without Motor for Oil
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.

Constant-Flow-Rate Pumps without Motor for Chemicals
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.

Self-Priming Circulation Pumps without Motor for Oil
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.
Note: Pumps must be filled with liquid before use. They need a constant flow of liquid and cannot run dry.

Circulation Pumps without Motor
Also known as centrifugal pumps, these send a high flow of liquid through a pipeline or a closed circuit. They’re often used in heating and cooling applications, as well as for tank filling and emptying. Connect them to a spark-free air motor for hazardous locations, or use an electric motor with a speed reducer or belt pulley to alter pump speed. Recommended for use with 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.
