Circulation Pumps for Water and Oil

These pumps can be used to move water and lubricating oil in boiler feed systems, cooling towers, and heat exchangers. The housing rotates for vertical or horizontal discharge. They have totally enclosed fan-cooled (TEFC) motors 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.
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 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.

Sanitary Electric Drum Pumps

Commonly used in food, beverage, pharmaceutical, and cosmetic processing, these pumps are designed for sanitary environments. The discharge connection can be easily disassembled for cleaning. Pumps do not include a drum connector.
Pumps with a maximum viscosity of 100,000 cP handle a wide range of liquid thicknesses from water up to lotions and pie fillings.

Sump Pumps without Float Switch for Sewage Water

Pumps activate when plugged in. You can add a plug-in switch to control when the pump activates. Equipped with a large intake and rugged impeller, these pumps transfer raw sewage water with solids up to 2" in diameter. They have a cast iron housing that stands up to demanding environments. Submerge while in use and do not run dry.

Electric Vacuum Pumps


Use these pumps in applications such as degassing and servicing refrigeration and freezer systems. Maximum flow rate is the rate at which air is pumped before a vacuum is created. Flow rate steadily decreases as the pump generates the vacuum. The larger the tank, the longer it will take to form a vacuum. Tube and fitting ID will also affect flow.

Electric Air Compressors


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.

Fire Sprinkler Electric Air Compressors
Maintain air pressure in your sprinkler system. These piston air compressors turn on when their tank pressure drops to the actuation point, then turn off when it reaches the maximum. They are UL and C-UL listed, as well as CSA and CSA-US certified, so they meet U.S. and Canadian safety standards.

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.
Compressors for continuous duty can run without a cooling period. They’re designed for applications that require a constant supply of compressed air.
Note: Pair air compressors with the listed oil (sold separately) to extend their service life.

Electric Air Compressors with Aftercooler

Power equipment with built-in moisture control—these air compressors have a built-in aftercooler that cools down air leaving the compressor to remove condensation. This helps relieve the strain on your separator and dryer down the line. These compressors are useful for air-powered tools, where corrosion can clog air lines, and for control systems, where moisture can disrupt signals.
These compressors use pistons to pressurize air in two stages—compressing air, cooling it, and then compressing it again. This two-step process reduces wear, limits heat buildup, and improves overall efficiency. The integrated aftercooler cools the air as it exits the compressor, condensing any remaining moisture so it can be drained before it causes an issue. The automatic drain clears the condensate from the tank to keep everything running smoothly—especially important in high-moisture lines.
These compressors turn on when tank pressure drops to the actuation point and shut off when it reaches maximum pressure. They can run continuously without a cooling period. If you plan to run them continuously, use SAE 30 synthetic oil (sold separately) to maintain performance and efficiency.
