Exchanging the dosing hose of the dosing pump
The pump hose in the pump
is subject to mechanical and
chemical stress. The pump
hose must therefore be
regularly checked to detect
damage in due time and
exchange the hose set.
Components of the hose dosing pump:

Exchanging the pump hose:
Gently pull the hose holder forwards at the suction and pressure connection and
remove the transparent pump cover and the lock washer in order to exchange the
pump hose. Turn the roller carrier to the left and pull the dosing hose forwards
through the recess in the roller carrier. Pull the hose holder with the dosing hose
out of the guide and carefully remove the cable ties at the hose connections with a
sharp knife or with pliers while taking care that the hose nipple is not damaged.
Push the new dosing hose onto the hose nipples up to the limit stop, so that the
markers at the hose ends are in front. This ensures that the hose is not twisted.
