6. Maintenance
6.1. General
The pump as well as the entire system must be inspected and maintained at regular intervals. The interval of the
maintenance is determined by the manufacturer and applies for the general conditions of use. The manufacturer
must be contacted in the event of aggressive and/or abrasive pumped mediums, since the interval could be
shortened in these cases.
The following points must be noted:

The operating instructions must be available to the maintenance personnel and must be followed.
Only maintenance work and measures listed here must be carried out.

All maintenance work, inspection work and cleaning work on the machinery and the system must be
carried out with due diligence, at a safe working place and by trained qualified personnel. The
required protective gear must be worn. The machinery must be disconnected from the power supply
for all work. Unintentional start must be prevented. Furthermore the respective protective measures
according to the Employers' Liability Association regulations, BGV/the Statutory Accident insurance,
GUV must be complied with when working in basins and/or containers.
Ensure that sling gear, ropes and the safety equipment of the hand winch are technically sound. The work
must only be started when the auxiliary hoisting gear is technically in order. Failure to carry out these
checks may jeopardize your life!

If easily inflammable dissolvers and cleaning materials are used, open fire, open light as well as
smoking are prohibited.

Ensure that the required tools and materials are readily available. Tidiness and cleanness ensure
safe and proper work on the machinery. Remove used cleaning materials and tools from the
machinery after the work has been carried out. Keep all materials and tools in a dedicated place.

Service media (such as for example oils, lubricants, etc.) must be captured in a suitable container
and must be disposed of according to the local regulation. Respective protective clothing must be
worn when carrying out cleaning work and maintenance work. Only lubricants recommended by the
manufacturer must be us
ed. Oils and lubricants must not be mixed. Only use manufacturer’s original
parts.
A test run or function test of the machinery must only be carried out according to the general operating
conditions!
6.2. Maintenance intervals
Every six months:

Visual inspection of the power supply leads

Visual inspection of the cable holders and the wiring

Visual inspection of accessories, such as for example suspension device, lifting devices, etc.
6.3. Maintenance work
Check of the used switchgears for resistance, sealed space control etc.
Check the used switchgears for correct function. Defective devices must be replaced immediately, since they do
not ensure protection of the machinery. Instructions for the test procedure must be followed (operating
instructions for the respective switchgears).
Visual inspection of the power supply leads
The power inlet leads must be inspected for bubbles, cracks, scratches, scour marks and/or crushing zones. If
damages are detected, the damaged power inlet lead must be replaced immediately.
The leads may only be replaced by the manufacturer or an authorized/certified service workshop. The
machinery must only be started after appropriate repair of the damage!
Visual inspection of the cable holders (biners) and the wiring (traction cable)
If the machine is used in basins/shafts the hoisting wires/cable holders (biners) and the wiring are subject to
constant wear and tear. Regular inspections are required to prevent a complete wear and tear of the hoisting
wires/cable holders (biners) and/or wiring and a complete damage to the power cable.
The hoisting wires/cable holders (biners) and the wiring must be replaced immediately if there are slight
signs of tear and wear!
Visual inspection of accessories
The accessories, such as for example suspension devices, lifting devices, etc. must be checked for correct fitting.
Loose or defective accessories must be repaired/replaced immediately.
