A pneumatic pump for a 55-gallon drum is a device that uses compressed air to transfer liquids (such as oils, chemicals, fuels, or solvents) from the drum to another container or system. These pumps are ideal for handling hazardous or viscous fluids safely and efficiently.
Diaphragm Pumps
How it works: Uses a flexible diaphragm driven by compressed air to move liquid.
Best for: Chemicals, solvents, oils, and viscous fluids.
Pros: Self-priming, dry-run capable, handles abrasive fluids.
Cons: Requires clean, dry air supply.
Piston Pumps
How it works: Uses a reciprocating piston to move liquid.
Best for: High-pressure applications, thicker fluids.
Pros: High flow rates, good for viscous liquids.
Cons: More maintenance required than diaphragm pumps.
Rotary Lobe Pumps
How it works: Uses rotating lobes to move fluid.
Best for: Food-grade, sanitary, or shear-sensitive liquids.
Pros: Gentle on fluids, easy to clean.
Cons: Higher initial cost.
Flow Rate: Typically 1–20 GPM (gallons per minute), depending on the pump type.
Air Pressure Requirement: Usually 50–100 PSI.
Material: Stainless steel, aluminum, or polypropylene (choose based on chemical compatibility).
Hose & Nozzle Size: Standard sizes (e.g., ½" or ¾") for easy dispensing.
Explosion-Proof Options: Needed for flammable liquids.
Flux Pumps (e.g., Flux B30) – Reliable diaphragm pump for chemicals.
Lutz Pumps – Great for oils and fuels.
Yamada – High-quality air-operated diaphragm pumps.
Goat Throat Pumps – Popular for solvents and hazardous materials.
