Constant-Flow-Rate Pumps for Water
Also known as gear pumps, these produce a smooth flow of liquid for applications such as cooling engines, powering hydraulic equipment, and extracting liquid from holding tanks. Pumps are self-priming after you fill the pump chamber with liquid. As liquid in the chamber is expelled, a suction force is created which allows the pump to draw liquid upward. Do not use with solids. Pumps can be used in dusty, dirty, and damp environments.
Pumps that cannot be sold to Canada are restricted by local energy efficiency requirements.
Note: Pumps must be filled with liquid before use. They need a constant flow of liquid and cannot run dry. 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.

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

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.
