Pump Options on Standard and Deluxe Models

Piston Sprayer Pumps

Piston prayer Pumps are the most popular. These allow a wider range of applications than diaphragm sprayer pump models. Not recommended for use with abrasive sprays or wettable powders. Deliver 60 psi. NOTE: Models D425 and L435 can reach 90 psi with an optional plug installed.

Diaphragm Sprayer Pumps

Diaphragm Sprayer Pumps generate a lower pressure than piston pumps, which results in larger liquid droplets and less spray drift. Diaphragm pumps are effective with abrasive sprayer and wettable powders, unlike piston pumps.
