High-Head High-Efficiency Circulation Pumps for Water, Coolants, and Oil

Propel liquid higher and farther than standard high-efficiency circulation pumps. These pumps use less electricity to achieve the same flow rates as other circulation pumps. They have a totally enclosed fan cooled (TEFC) motor for use in dusty, dirty, and damp environments. Adjust the housing studs to make the discharge direction more vertical or horizontal. 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. They cannot be sold to the regions listed due to local energy efficiency requirements.

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 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.

High-Flow Harsh-Environment Self-Priming Circulation Pumps for Water and Coolants

A powerful motor provides twice the flow rate of other self-priming circulation pumps. It is totally enclosed fan-cooled (TEFC) for use in dusty, dirty, and damp environments. Install these pumps up to 20 ft. above your liquid source to drain underground tanks and process wastewater. They 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.

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.

Electric Air Compressors


Vertical	Horizontal

From lifting heavy objects to mixing large vats, these compressors power the equipment that keeps your production line going. They use pistons to compress air in two stages to generate higher pressures and flow rates than single-stage compressors. This two-step process—compressing air, cooling it, and compressing it again—prevents heat and reduces wear, so you can run them continuously.

When choosing a tank size, keep in mind a larger tank capacity means you won't have to run them continuously, which extends their life. These compressors turn on when tank pressure drops to the actuation point and shut off when it reaches maximum pressure.

If you plan to run them continuously, use SAE 20 synthetic oil (sold separately) to maintain performance and efficiency.

Economy Electric Air Compressors

Designed with occasional use in mind. These two-stage compressors deliver the same high pressures and flow rates as standard models, but their undersized motor must work twice as hard. They run hotter, louder, and are less durable than more expensive two-stage compressors.

These air compressors turn on when tank pressure drops to the activation point and shut off when it reaches maximum pressure. They can run continuously without needing a cooling period. Use SAE 30 synthetic oil (sold separately) to maintain performance and efficiency.

Light Duty Electric Air Compressors

Pressurize air to power drills, wrenches, and grinders. Because they’re single-stage, these compressors are best for infrequent use. They turn on when tank pressure drops to the actuation point and shut off when it reaches maximum pressure. Hardwire them to your power source. Choose a compressor with a tank size that matches your application. The larger the tank, the more tools it can power. A greater reserve of air means the compressor can run less often, which keeps it cool and improves energy efficiency for a longer life.

Continuous Duty—Compressors for continuous duty can run without a cooling period. They’re designed for applications that require a constant supply of compressed air.

Oil—Pair air compressors with the listed oil (sold separately) to extend their service life.

Low-Noise Electric Air Compressors

As quiet as an idling forklift, these rotary screw compressors make less noise than traditional piston compressors but deliver the same power. They turn on when tank pressure drops to the actuation point and off when it reaches the maximum. Use them for manufacturing, processing, and packaging jobs where steady output matters—you can run them continuously. If you plan to run them continuously, use SAE 20 synthetic oil (sold separately) to maintain performance and efficiency.
