Air-operated diaphragm pump

The FloJet G573215Z is a double diaphragm pump driven by compressed air. Its polypropylene body and Viton diaphragms resist a wide range of chemicals. Maximum flow reaches 5 gpm through half-inch barbed ports. The unit suits fluid transfer tasks where electric power is unavailable or unsafe.

Chemical transfer and fluid handling

This pump serves operators moving aggressive liquids, solvents or acids in industrial and marine settings. Air drive eliminates spark risk in hazardous areas. Buyers who need metered dosing, high-pressure delivery or electric motor operation should look at alternative pump types.

5 gpm maximum flow rate

The 5 gpm peak flow determines whether the pump can meet your required transfer speed. Check your system demand against this figure before purchase. If your application needs higher volume, a larger pump will be necessary.

Questions about this item

What does the 5 gpm maximum flow rate mean when the pump is installed in a system?

The pump can move up to five gallons per minute of fluid under optimal air pressure and unrestricted piping; actual flow will be lower if hoses, fittings or head pressure add resistance.

How does the 1/4 inch barbed air intake connection limit the air supply I can use?

The barbed fitting accepts 1/4 inch inside-diameter tubing, so the air line and regulator must match that size; a larger supply hose will need a reducer to fit securely.

What mounting considerations come from the bottom intake and discharge ports on this pump?

Both fluid ports face downward, so the pump must be positioned with clearance beneath it for 1/2 inch barbed hoses and fittings, and the mounting surface should support the pump body above those connections.
