Compact Drum Pumps for Water and Chemicals

Designed to move low volumes of caustic liquids in confined areas, these pumps have a thin intake tube and a small handle. They are often used to pump cleaning fluids, acid-washing solutions, and bleach.
Style A pumps have a selectable flow rate, so you can adjust flow for different dispensing applications.

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. They have a chemically resistant seal for use with hydraulic oil and motor oil in addition to acidic and alkaline liquids such as ammonia and etching and cleaning solutions. 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 (MEK) and xylene. Also known as diaphragm pumps, they have few moving parts that can fail for a long service life. Install an air line filter/lubricator to ensure efficiency and reduce wear on the pump.
Repair kits include O-rings, valves, and diaphragms.

Fixed-Flow-Rate Metering Pumps for Chemicals
Also known as peristaltic pumps and 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.
Pumps with Viton® fluoroelastomer tubing withstand oil such as gasoline and hydraulic oil.

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. Pumps are self-priming, which means they create a suction force to draw liquid upward to fill the pump chamber. All can run dry.
Fluid-side maintenance kits include diaphragms, check valve balls, and seals.
Air-motor maintenance kits include seals, O-rings, gaskets, retaining rings, and an air valve spool.

Noncontact Flow-Adjustment Valves
- Valve Type: Pinch
- For Use With: Water, Oil, Air, Deionized Water, Diesel Fuel, Ethylene Glycol, Fuel Oil, Isopropyl Alcohol, Kerosene, Methanol, Mineral Spirits, Sodium Hydroxide, Sodium Hypochlorite
Also known as pinch valves, these press down on the outside of tubing to adjust flow without contacting the process media. They can be used with any media that’s chemically compatible with your tubing.
Nickel-plated brass valves are more corrosion resistant than zinc or zinc-plated steel valves.
Valves with an open body provide easy access to tubing for maintenance or replacement.
Valves with a closed body securely hold tubing in place.

Threaded Precision Flow-Adjustment Valves for Chemicals
To withstand aggressive and corrosive solutions in chemical-processing applications, these valves have a fluoroelastomer seal and a plastic body. Turn the handle to adjust flow in small increments for metering, sampling, and other applications requiring fine flow control.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.
