Sodium Hydroxide Oilers | McMaster-Carr

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.

Whenever working with flammable liquids, always bond and ground your application for static control. For more information about bonding and grounding, see Sections 1910.106 and 1910.107 of the Federal OSHA Code or see bonding and grounding equipment.

Drum Pumps for Water and Chemicals

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

Styles A, B, and G are for thin liquids with a maximum viscosity of 700 or 750 centipoise.

Styles C-F are rated for liquids up to 2,500 centipoise. Style C are often used as hand pumps and do not come with a connector. To attach them to a container, select an optional connector.

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 (MEK), xylene, and mineral spirits. Motor is nonsparking for use in applications where electricity is unavailable or dangerous. Install an air line filter/lubricator to ensure efficiency and reduce wear on the pump.

Always bond and ground your application for static control. For more information about bonding and grounding, see Sections 1910.106 and 1910.107 of the Federal OSHA Code or see bonding and grounding equipment.

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. Pumps are self-priming, which means they create a suction force to draw liquid upward to fill the pump chamber. All are submersible and can run dry.

Fluid-side maintenance kits include diaphragms, check valve balls, and seals.

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. They automatically turn on when you open the outlet valve. Pumps are self-priming, which means they create a suction force to draw liquid upward to fill the pump chamber. Do not run dry.

Buna-N diaphragm is oil resistant and often used with detergents.

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. 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.
