Constant-Flow-Rate Gear Pumps without Motor for Water
 |
These gear 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. 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.

Constant-Flow-Rate Gear Pumps for Oil
 |
A high-horsepower motor moves oil with a viscosity similar to SAE 60 motor oil. These gear pumps produce a smooth flow of liquid to lubricate equipment and blend oils. Motor is open dripproof (ODP) for use in clean, dry, and well-ventilated 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.

Constant-Flow-Rate Gear Pumps for Water
 |
These gear pumps 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.
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.
Cannot Be Sold to Canada—Pumps that cannot be sold to Canada are restricted by local energy efficiency requirements.
