Description
When you’re mixing chemicals or running a sprayer, you need a pump that’ll keep steady pressure and won’t let you down mid-job. This Delavan bypass pump is built for exactly that—delivering a consistent 2.0 GPM flow while automatically regulating pressure at 60 PSI. No demand switch needed, just reliable performance when you’re laying down herbicide, insecticide, or liquid fertilizer.
What You’re Getting
- Steady 2.0 GPM flow rate that’s perfect for boom sprayers and spot spraying
- Built-in 60 PSI bypass keeps pressure consistent without needing a separate switch
- Viton check valve stands up to harsh chemicals and won’t deteriorate like rubber
- Santoprene diaphragm handles temperature swings and chemical exposure
- Standard 3/8 inch NPTF ports fit most sprayer plumbing setups
Built for Chemical Applications
This pump works great on pull-behind sprayers, three-point sprayers, and ATV-mounted units where you need dependable chemical delivery. Whether you’re spot-treating weeds along fence rows, applying pre-emergent in the spring, or doing a full-field application, the bypass feature means you can vary your ground speed without worrying about over-pressurizing your system.
Made to Last
Farm chemicals are tough on equipment, but this pump uses materials that can handle the abuse. The Viton seals resist swelling and cracking from ag chemicals, while the santoprene diaphragm stays flexible even when temps drop. It’s the kind of pump that’ll keep working season after season.
Good to Know
The bypass feature means excess flow automatically returns to the tank instead of building pressure—handy when you’re stopped or running at variable speeds. Make sure your tank has a return fitting, or you can tee into the suction line. Keep a spare diaphragm kit on hand for busy spray seasons.
