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.

Air-Powered Constant-Flow-Rate Pumps
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.
