Maintenance

WARNING

When dosing dangerous media, observe the
corresponding safety precautions!

Wear protective gloves and glasses when executing
work at the dosing head, connections or lines!

Do not open the pump!
Repair only by authorized personnel!

Switch off the pump and disconnect from mains before
doing maintenance and repair!

9.1

Replacing the Gear Grease

WARNING

The gear grease may only be changed by authorized,
qualified personnel. For this purpose send the pump to
the factory.

To guarantee fault-free operation, it is recommended to have the gear grease
exchanged after 5 years or after 20000 operation hours.

9.2

Rates for cleaning and maintenance

❏

Regularly every 12 months or after 4000 operation hours, or

❏

in case of malfunction

Clean the diaphragm and valves, or replace if necessary (with stainless steel
valves: internal components). -> see spare parts

9.3

Cleaning the Suction and Pressure Valves

WARNING

Wear protective gloves and glasses when executing
work at the dosing head, connections or lines!

If the pump loses capacity, clean the suction and pressure valves as follows:

●

Unscrew the valve

●

Unscrew the screw part or the

valve seat with round pliers.

●

Clean all parts, replace faulty parts by new ones.

●

Re-assemble the valve.

●

Replace the O-rings by new ones, and place the valve. Observe the direction
arrow.

CAUTION

Take heed that the O-ring is fitted exactly into the
provided groove.

CAUTION

Observe the flow direction (indicated by an arrow)!

Tighten the valves only by hand. Danger of damage!
