Chemical Induction Hopper
Overview
The Chemical Induction Hopper is an alternative
method of transferring chemical into the main
spray tank. The hopper can be lowered to a more
convenient height for adding chemicals. The chemical
can either be in liquid form or granular form and
once in the hopper the chemical can then be easily
transferred into the main spray tank. The hopper
facilitates drum rinsing with fresh water and the
hopper itself can be rinsed and all rinsate then
transferred into the tank.
The hopper transfers the chemical via venturi effect.
Water from the main spray tank is pumped under
the bottom of the hopper where it passes through a
venturi fitting under the hopper. This causes a suction
effect and when the bottom of the hopper is open
(via the hopper tank valve) the tank contents are
drawn into the flow from the pump passing under
the hopper and then transferred into the middle of
the main spray tank. This eliminates chemical attack
resulting from high concentrations of chemical
coming into contact with spray components.
NOTE: The level indicator should be used as a guide
only.
NOTE: Never let the hopper run empty or suck air,
this may cause foaming in the main tank.
