30 ml Canister pump

Metering system (30 ml per stroke), direct screw top for the 3 and 5 l canisters used here for fertilizers and water treatment.

Replaces the original screw top of the canister. Delivered in these individual pieces which have to be assembled before use:

Step 1

Nest the transparent tube into the lower part of the pump. Press the seal in the large ring nut.

Step 2

Screw the pump at the small ring nut and disperse it. Put both parts in parallel as seen on the illustration.

Step 3

Nest the large ring nut with the seal above the thread at the bottom part of the pump as seen on the illustration.

Step 4

Nest the upper component of the pump with the steel spring into the bottom part again.

Step 5

Connect upper component and bottom part with the small ring nut definitely. You'll need a little pressure to overcome the steel spring's resistance.

Step 6

Delete the canister's screw cap.
Nest the total pump construction into the canister's vent (with smaller canisters the transparent service pipe needs to be shortened if necessary. Just bevel with a cutter or shear.) and tighten with the large ring nut. Mind the pump's outlet showing to the desired direction (to adjust just loosen the ring nut slightly).
