Automatically control output from a distance using 4‐20 mA or external-pulse signals. These pumps meter a consistent amount of liquid within ±2% of the maximum flow.

Also known as peristaltic pumps and tubing pumps, these maintain a fixed flow rate.

Rated for liquids with a viscosity up to 5,000 centipoise, these pumps can be used with thick chemicals such as electropolishing solutions.

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 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.

Dispense precise amounts of fluid from a syringe. Commonly used in chemical and pharmaceutical research, fiber production, and equipment calibration, these pumps maintain a steady flow rate for accurate filling and measuring.

Inject chemicals into your water supply without using electricity—these pumps install directly in your pipeline and activate when water flows into the pump head.

Use these pumps for high-pressure output of antifreeze, hydraulic oil, and motor oil.

Operating on a 12-volt battery, use these pumps to transfer and drain fuel such as gasoline, diesel fuel, and kerosene.

Keep your circulation pump in working order by replacing broken or worn parts.
