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.

Any-Direction Constant-Flow-Rate Pumps for Water
Mount these pumps in any position, even upside down. Pumps have a subfractional horsepower motor rated for intermittent use (return to room temperature before restarting). Also known as diaphragm pumps, they are for use in low-flow spraying, draining, and washdown applications. They are self-priming, which means they create a suction force to draw liquid upward. Pumps can run dry and do not require an initial fill, so they’re a good choice for applications without a constant flow of liquid. Do not use with solids.
Battery-operated pumps operate on a 12-volt battery. They are commonly used with agricultural sprayers and washers.
Pumps with a pressure switch automatically shut off the pump at the maximum pressure.

Remote-Adjustment High-Accuracy Metering Pumps for Chemicals
Automatically control output from a distance using 4-20 mA or external-pulse signals. View the flow rate on the backlit LCD. These pumps meter a consistent amount of liquid within ±2% of the maximum flow. Often used to pump water-treatment chemicals, cleaning fluids, and electropolishing solutions, they have an adjustment dial that alters flow rate in 2% increments of the maximum flow. Pumps can run dry. Do not use with solids.
Repair kits include a pump head assembly, a diaphragm, valves, and seals.

Miniature Metering Pumps for Chemicals
With a footprint that's only a few inches in any direction, these pumps fit into compact systems to dispense small amounts of acids, cleaning fluids, and other chemicals. They're often used in sterilization, photochemical, and water treatment systems. Choose from pumps with either a 4-20mA or 1-5V DC input signal that controls the flow rate.
Note: Pumps must be filled with liquid before use. They need a constant flow of liquid and cannot run dry.

High-Pressure Metering Pumps for Chemicals with Locking Lever
An adjustment dial with a locking lever allows for easy flow control. Also known as diaphragm metering pumps, these can be used with pressures up to four times higher than standard chemical metering pumps. They're often used for general purpose dispensing of chemicals such as ammonia and acid-washing solutions. The adjustment dial alters flow rate in 5% increments of the maximum flow. Pumps are self-priming and create suction to draw liquid upward. Do not run dry or use with solids.
Repair kits include a pump head assembly, valves, a diaphragm, and mounting hardware.

Metering Pumps for Coolants and Oils
Use these pumps for high-pressure output of antifreeze, hydraulic oil, and motor oil. They have an internal relief valve to prevent pressure buildup. The adjustment dial alters flow rate in 1% increments of the maximum flow. Pumps have a totally enclosed fan-cooled (TEFC) motor for use in dusty, dirty, and damp environments. Do not run dry or use with solids.
