I have a 3 pump Profilux slave doser for sale. $125 shipped. The unit is in excellent condition with all 3 pumps working properly. The doser does require a Profilux controller or Profilux stand alone doser to be used automatically. You can use it to manually dose by pushing and holding each pump button (not sure why you'd want to, but it is possible). There is space to add a 4th pump if you'd like.
