Buying Guide

Match pump type to application

Diaphragm pumps handle chemicals and low-pressure spraying well—choose them for agricultural pesticide and foliar applications rather than high-pressure irrigation systems

Choose the right flow rate (GPM)

Select a flow rate that matches your sprayer boom or nozzle needs; models here range from about 2.5 to 5.5 GPM to cover small tractor-mounted sprayers up to larger spot-spray rigs

Check pressure rating (PSI)

Maximum pressure determines nozzle compatibility and spray droplet size—60 PSI models are common in this set and suitable for many broadcast and spot-spray tasks

Consider pressure-switch features

Integrated pressure switches automate pump cycling and reduce wear by maintaining set pressure, useful when paired with boom systems or automated controls

Verify electrical and fitting compatibility

Confirm 12V power draw and connector type for vehicle or battery use, and check inlet/outlet fittings (for example 1/2" FNPT) to match hoses and valves
