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.
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.

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.

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.
- Valve Type: Needle
- For Use With: Water, Oil, Beverage, Citric Acid, Deionized Water, Diesel Fuel, Ethanol, Ethylene Glycol, Food, Fuel Oil, Gasoline, Hydrochloric Acid, Isopropyl Alcohol, Kerosene, Methanol, Mineral Spirits, Phosphoric Acid, Salt Water, Soap Solutions, Sodium Hydroxide, Sodium Hypochlorite, Sulfuric Acid
- Seal Material: Fluoroelastomer Rubber
- Seat Material: PTFE Plastic
- Needle Material: Polypropylene Plastic

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. Threads and a hex nut below the handle allow you to install these valves in instrument panels. They have a nut that can be tightened to compress the packing if it leaks.

Chemical Hose Nozzles with Hose and Cam-and-Groove Fittings
Dispense chemicals from a line that attaches and detaches from your drum or intermediate bulk container (IBC) in seconds. These nozzles and the included hose come with fittings that connect when you insert the plug into the socket and push the levers down. To resist corroding from citric acid, ethanol, and other chemicals, these nozzles are made of either polypropylene or aluminum and the hose is PVC. These nozzles are not designed for pressurized systems and should be used in applications where liquid can flow by gravity. Use the trigger to adjust how much they dispense at a time. These nozzles swivel to make directing the flow easier. Hook the included bracket onto the top of a drum or tank to hang the hose when not in use.
Polypropylene nozzles are lighter in weight than aluminum nozzles and resist corroding from harsher chemicals, such as phosphoric acid.
Aluminum nozzles resist wear and tear better than polypropylene nozzles.
