Automatically control output from a distance using 4-20 mA or external-pulse signals. View the flow rate on the backlit LCD. These diaphragm 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.

Pump Repair Kits—Repair kits include a pump head assembly, a diaphragm, valves, and seals.

Also known as tubing pumps, these maintain a fixed flow rate. Pumps are self-priming, which means they create a suction force to draw liquid upward and fill the pump chamber. Mount them up to 25 feet above your liquid source. All can run dry. Do not use with solids.

Add faucets to oil dispensing stations for increased utility.

With a footprint that's only a few inches in any direction, these diaphragm 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.

An adjustment dial with a locking lever allows for easy flow control. These metering diaphragm pumps can be used with pressures up to four times higher than standard chemical metering diaphragm 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.

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 are self-priming and create suction to draw liquid upward. They can run dry but are not for use with solids.

Driven by an air-powered pump, this dispenser comes with an adapter to mount through a bung opening on a drum of oil (not included).

For high-volume chemical sampling and draining, these pumps have a powerful motor that enables them to move 2,592 gallons of liquid per day. They're commonly used with ammonia, acid-washing solutions, and cleaning fluids. Motor is open dripproof (ODP) for use in clean, dry, and well-ventilated environments. Pumps are self-priming and create a suction force to draw liquid upward. Mount up to 15 feet above your liquid source. They can run dry. Do not use with solids.

Connect these dispensing stations to your bulk oil container to easily fill hand-held dispensers. They include one faucet and can fit up to three, so you can access different types of oil at a single centralized point.
