Pumps

Selectable-Flow-Rate Easy-Stroke
Drum Pumps for Water and Chemicals

These pumps have a selectable flow rate, so you can adjust flow for different dispensing applications. A lever handle maximizes output with each stroke for low-effort dispensing.

Drum Pumps for Water and Chemicals

Push the plunger to pump water, cleaners, and chemicals.

Smooth-Flow Drum Pumps for Water and Chemicals

Rotate the handle to dispense a continuous flow of liquid.

Nondrip Drum Pumps for Water and Chemicals

Eliminate leaks and waste with a faucet-style nondrip nozzle that quickly starts and stops flow.

Siphon Drum Pumps

Since these pumps use suction to draw liquid out of your container, they continue dispensing once you get them started.

Adjustable-Flow Electric Drum Pumps
for Water, Oil, Coolants, and Chemicals

Alter the flow rate for versatile dispensing.

Electric Drum Pumps for Water, Oil, and Chemicals

Drain and transfer liquid more quickly and easily than hand-operated pumps and siphon pumps.

Hazardous Location Electric Drum Pumps
for Water, Oil, Coolants, and Chemicals

These pumps quickly empty drum contents by moving 48 gallons of liquid per minute. Their electric motors are UL listed for use in environments with flammable gases and combustible dust.

High-Flow Electric Drum Pumps for
Water, Oil, Coolants, and Chemicals

Designed to move 40 gallons of liquid per minute, these pumps quickly empty drum contents.

Electric Drum Pump Systems for
Water, Oil, Coolants, and Chemicals

Including nozzles and connectors, these pumps come with everything you need to start pumping.

Air-Powered Drum Pumps for Flammable Liquid

These pumps have a motor that is rated for IEC Zone 1, Groups IIB and IIA; and IEC Zone 21, Groups IIIC, IIIB, and IIIA hazardous locations with flammable gases and vapors, so they can be used with liquids such as acetone, ethanol, methyl ethyl ketone, xylene, and mineral spirits.

Air-Powered Drum Pumps for
Water, Oil, Coolants, and Chemicals

Often used with ammonia, etching and cleaning solutions, and other caustics, these pumps have a nonsparking air-powered motor for applications where electricity is unavailable or dangerous.

Air-Powered Drum Pumps with Hose
and Filter/Lubricator for Water,
Oil, Coolants, and Chemicals

A filter/lubricator ensures efficiency and reduces wear on the pump. Often used with hydraulic oil and motor oil in addition to acidic and alkaline liquids, these pumps have a nonsparking motor for use in applications where electricity is unavailable or dangerous.

PVDF Extended-Life Air-Powered
Drum Pumps for Chemicals

A chemical- and impact-resistant PVDF housing stands up to aggressive chemicals such as methyl ethyl ketone and xylene.

Polypropylene Extended-Life
Air-Powered Drum Pumps for Chemicals

The polypropylene housing provides good resistance to caustics such as ammonia, electropolishing solutions, and detergents and cleaning fluids.

316 Stainless Steel Air-Powered Transfer Pumps
for Chemicals, Fuel, and Flammable Liquids

With a 316 stainless steel housing and a PTFE diaphragm, these pumps resist a variety of acids, alkalies, and flammable liquids such as phosphoric acid, acetone, and methyl ethyl ketone (MEK). They're designed for moving large volumes of thick sludges and slurries in demanding environments.

PTFE Air-Powered Transfer
Pumps for Harsh Chemicals

With all PTFE wetted parts, these pumps offer the best chemical resistance of all our air-powered transfer pumps and can handle solvents and petroleum-based fluids that PVDF pumps can’t.

Smooth-Flow Air-Powered Transfer Pumps

Also known as sprayer pumps, these provide a smooth, uniform flow for agricultural spraying, soap dispensing, and chemical transferring.

High-Accuracy Metering Pumps for Chemicals

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

Remote-Adjustment High-Accuracy
Metering Pumps for Chemicals

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.

High-Flow Metering Pumps for Chemicals

For high-volume chemical sampling and draining, these pumps have a powerful motor that enables them to move 2,448 gallons of liquid per day.

Flow-Adjustment Valves

Threaded Precision Flow-Adjustment
Valves for Chemicals

Use these valves with NPT threaded pipe. They have a fluoroelastomer seal and a plastic body to withstand aggressive and corrosive solutions in chemical-processing applications. Turn the handle to adjust flow in small increments for metering, sampling, and other applications requiring fine flow control.

Precision Flow-Adjustment Valves
with Barbed Fittings for Chemicals

Barbs grip onto tubing, providing a secure hold. To withstand aggressive and corrosive solutions in chemical-processing applications, these valves have a PTFE seal and a PVDF body. Turn the handle to adjust flow in small increments for metering, sampling, and other applications requiring fine flow control.

Precision Flow-Adjustment Valves
with Yor-Lok Fittings for Chemicals

For extra gripping power and a strong seal, these valves have Yor-Lok fittings with two sleeves that bite into tubing as you tighten the nut. All are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings. The 316 stainless steel body and seal, the PTFE seat and packing, and the Monel needle can withstand aggressive and corrosive solutions in chemical-processing applications. Turn the handle to adjust flow in small increments for metering, sampling, and other applications requiring fine flow control.

Precision Flow-Adjustment Valves with
Push-to-Connect Fittings for Chemicals

Insert tubing into the fittings on these valves—no heat, solder, or flux required. With a fluoroelastomer seal and a PVDF body, they can withstand aggressive and corrosive solutions in chemical-processing applications. Turn the handle to adjust flow in small increments for metering, sampling, and other applications requiring fine flow control.

Plastic Noncontact Flow-Adjustment Valves

With no metal parts, these valves are often used for noncontact flow adjustment in wet conditions and harsh environments. All press down on the outside of tubing to adjust flow without contacting the process media.
