Our very durable HD400 is extremely popular with landscape professionals and organic farmers. The 4-gallon (16-liter) HD400 has an internal mechanical agitator that does an excellent job of keeping powdered chemicals such as kaolin clay organic insecticides in suspension, as well as liquid chemical additives.
he HD400 only takes 6 handle pumps to achieve 45 psi, reducing operator fatigue. It has a convenient carry handle built into the top of the tank, a handle lock and spray lance lock to make it easy to transport from job to job.
We offer two color combinations for the HD400: The white/orange option is equipped with a Viton® piston cup, a choice for users who will spray caustic chemicals. Our HD400 blue features a piston cup made from Santoprene®, which offers a longer wear life than the Viton® option.
