Sprayer Characteristics

Our comparison testing determined that sprayer designs with the following four characteristics worked better than others:

1) Sprayers with large internally mounted piston pumps are more efficient. An internally mounted pump that leaks is much better than an externally mounted pump that leaks, reducing your exposure to pesticides.

2) Leveraging pump handle designs reduce arm fatigue operating the pump.

3) Lightweight tank design and carrier system to reduce overall weight.

4) Large fill spouts offset to the side to allow for easier filling and pouring out of products along with a pickup handle in the middle of the sprayer which is a nice addition to handling a fairly heavy item when filled with solution.

Model Availability Updates

Gate pressure regulating valve manufacturer source changed to Gate CFV, www.gatecfv.com, April 2015. Worldwide manufacturing of sprayer brands and models changes over time.

As of 2013, the Shindaiwa SP415 shown on the videos, and a very efficient backpack sprayer in our evaluations, is no longer sold.

Jacto model SP416 is a new model in 2013, with similar specifications and performance as the Shindaiwa SP415. The Jacto SP416 has a new trigger valve that accepts the 24- inch TeeJet brass extension shown in our materials list. Adding TeeJet trigger valve and valve handle, while not a necessary accessory, enables use of the TeeJet barbed swivel, improving the spraywand balance and user comfort. http://www.jacto.com/sprayers/backpack/index.html

H.D. Hudson offers a sprayer, model 93594 Regulator™ Bak-Pak® Poly 4 gal, which is similar in features to the Jacto SP 416 but requires complete spray wand replacement for TeeJet conversion . Also offered is a good quality rechargeable battery powered backpack sprayer, NeverPump® Bak-Pak® Sprayer Model 13854. http://www.hdhudson.com/professional-sprayers/professional-products/product-details/?id=182
