8.3 Cleaning the pump hose
Running the pump with clean water can clean the inside
of the pump hose. If a cleaning fluid is added to the
water, attention must be given to its compatibility with
the hose liner material, and also the temperature at
which the cleaning procedure will be performed.
Sometimes a cleaning sponge can be very helpful.
With many products, it is necessary to clean the pump
hose immediately once the pump is stopped to avoid
sedimentation and/or hardening of the product within
the hose that can cause damage upon restart.
8.4 Changing lubricant
1. Place a tray (A) under the drain plug in the
bottom of the pump. Remove the drain plug (B).
Catch the lubricant from the pump housing in
the tray. Check that the sealing ring (C) is not
damaged and replace it if necessary. Position
the drain plug and tighten it firmly.
11 Replacing wear ring. If necessary. See § 8.7.3 .
12 Replacing pressing
shoes. Wear on the running sur-
face. See § 8.7.2 .
13 Replacing bearings. If necessary. See § 8.7.4 .
14 Maintenance and peri-
odic inspection of the
gearbox and motor. Before start-up of the
pump and on a sched-
uled interval during oper-
ation. Check the manuals of
the gearbox and the
motor.
