First find out the following:

  • What is the strength of the dosing chemical?
  • What is the required dosing rate of the chemical?
  • What is the daily or weekly consumption?
  • What is the minimum delivery required?
  • What is the interval between deliveries?

The rest is just arithmetic.

Will the chemical come in a drum/barrel …..all you need is to install the pump on top of the barrel and set the speed / stroke ….. and activate it with a timer. How often it is tested ? -Who is recommending the chemical and supplying it …... What do they say.
