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.

High-Head Circulation Pumps for Water
Also known as booster pumps, these have a multistage impeller that propels water about two times higher and farther than standard circulation pumps. Use them in applications such as water delivery, irrigation, and pressure washing. The motor is totally enclosed fan-cooled (TEFC) for use in dusty, dirty, and damp 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.
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.

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