Plain dispenser pump (approx. 1.2 ml per stroke) for measuring fertilizer or adding water treatment.
Is attached directly to the bottle after the standard top is removed.
For the 250 ml, 500 ml and 1000 ml bottles.
Dispenser pumps are only watertight when they are bolted!
When this bolt is not closed, a ventilation ensures that no negative pressure builds up while pumping.
In order to prevent damages on your fittings and equipment, please do not tilt bottles with attached dispenser pumps during storage, as the content would inevitably leak out.
In order to keep it simple, the pipe feeds are designed for the largest bottle. For the small bottles or canisters these feed pipes must then be if necessary cut either using a knife or a pair of scissors.
