High-Pressure Constant-Flow-Rate
Pumps without Motor for Water
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.

Constant-Flow-Rate Pumps without Motor for Water
These pumps have a bronze housing and brass or bronze 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.

Self-Priming Circulation Pumps without Motor for Water
Also known as flexible impeller pumps, these 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.

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.
