These pumps meter a consistent amount of liquid within ±2% of the maximum flow.

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.

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.

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

Rated for liquids with a viscosity up to 10,000 centipoise, these pumps can be used with very thick chemicals such as electropolishing solutions.

An adjustment screw lets you increase or decrease flow rate without the hassle of changing tubing. Often used in boiler feed systems and water treatment, these pumps are compatible with chemicals such as cleaning fluids and acid-washing solutions.

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

Create vacuum suction quickly—by running water through the body of these aspirator pumps, you can draw liquids and gases in through the side arm. They’re often used in labs for vacuum filtration and picking up spilled liquids.

Made from PVC, these pumps are highly corrosion resistant and lightweight. Use them to produce emulsions, elevate water, and transport grains and other small particles.
