Harsh-Environment Compact Constant-Flow-Rate Pumps for Water and Oil
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.

Continuous-Duty Any-Direction Constant-Flow-Rate
Pumps for Water and Coolants
Rated for continuous use, this pump is often used to move caustics such as antifreeze and salt water. Mount it in any position, even upside down. Also known as a diaphragm pump, it is typically used for low-flow spraying, draining, and washdown applications. Pump has a pressure switch that automatically shuts off the pump at the maximum pressure. It is self-priming, which means it creates a suction force to draw liquid upward. Pump can run dry and does not require an initial fill, so it’s a good choice for applications without a constant flow of liquid. Do not use with solids.

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.

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

Harsh-Environment Self-Priming Water-Removal Pumps
This pump has a totally enclosed nonventilated (TENV) motor that is cooled by the liquid being pumped. Also known as a flexible impeller pump, it creates a suction force that can draw liquid upward to fill the pump chamber when your liquid source is below the pump. Mount up to 6 feet above your liquid source. Pump can pass solids up to 1/4" in diameter without clogging, so there’s no need to filter sediment and debris. A handle makes it convenient for on-the-go removal of bilge water, waste oil, and spills. Pump can also be used to cool marine engines and drain liquid from holding tanks.
Note: Pump must be filled with liquid before use. It needs a constant flow of liquid and cannot run dry.
