The SP2 is a professional backpack sprayer that revolutionizes the way external pumping systems operate. Using a patented process that completely seals the piston mechanism, the SP2 features a pump that is virtually leak-proof - something no other external unit has ever been able to claim. Capable of 160 psi, the SP2 combines safety with ultra-high pressure in a true 4-gallon sprayer that is the state of the art in comfort, quality and convenience.
Making and improving backpack sprayers since 1984, SP offers state-of-the-art operation and convenience. They are simple, hard-working, and made to last. They offer compression sprayers that require only one pumping session to empty the tank, piston pumps that dont leak, Viton seals and Nytril o-rings to stand up to strong chemicals such as 30% vinegar, and the lowest defect and return rate in the industry. They are a great value and last four to five times longer than other sprayers, have fewer working parts than other sprayers and are easy to maintain and service, require few or no tools to service or repair, and offer years of trouble-free use.
