
Switching frequency and pauses (see technical data)

If there is introduction of air in the feed stream, an impact plate must be fitted, if appropriate.

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.

For weights over 50 kg, technically flawless and licensed auxiliary lifting devices must be used for
lifting and lowering the machine.
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 jeopardise your life!

Electric works on the machinery and the system must be carried out by a specialist. For ex-
approved machines, you must also observe the "Ex protection" section in the annex!

If easily inflammable dissolvers and cleaning materials are used, open fire, open light and smoking
are prohibited.

Machines which circulate hazardous materials or come into contact with these must be
decontaminated. It is also important to ensure that no hazardous gases form or are present.

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 regulation 75/439/EEC and writ §§5a, 5b AbfG, Waste
Avoidance and Management Act). Respective protective clothing must be worn when carrying out
cleaning work and maintenance work. This must be disposed of according to waste catalogue TA
524 02 and EC directive 91/689/EEC. Only lubricants recommended by the manufacturer must be
used. 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!
Oil type: Biodegradable HOMA ATOX. Used oil must be disposed of properly.
When using white oils, please observe the following:

For refilling and/or initial filling, only operating fluids by the same manufacturer may be used.

Machines that were previously operated with other operating fluids must be cleaned thoroughly
before they can be operated with white oils.
