3.4 Recycling information

• Unpacking

- Packing material consists of wood, plastics, cardboard boxes and in some cases metal straps.

- Wood and cardboard boxes can be re-used, recycled or used for energy recovery.

- Plastics should be recycled or burnt at a licensed waste incineration plant.

- Metal straps should be sent for material recycling.

• Maintenance

- During maintenance,

oil and wear parts in the machine are replaced.

- All metal parts shoul

d be sent for material recycling.

- Worn out or defectiv

e electronic parts should be sent to a licensed handler for material recycling.

- Oil and all non-metal

wear parts must be disposed of in agreement with local regulations.

• Scrapping

- At the end of use, the equipment must be recycled according to the relevant, local regulations.

TD 252-019

Throttling!

4Operation

Pay attention to possible faults. Study the instructions carefully.

4.2 Fault finding

NOTE! Study the maintenance instructions carefully before replacing worn parts. - See section 5.1 General maintenance

Problem

Cause/result

Remedy

Overloaded motor

- Pumping of viscous liquids - Larger motor or smaller impeller

- Pumping of liquids with high density

- Low outlet pressure (counter pressure) - Higher counter pressure (throttling)

- Lamination of precipitates from the liquid

- Frequent cleaning

Cavitation:

- Damage - Low inlet pressure - Increase the inlet pressure

- Pressure reduction (sometimes to zero)

- High liquid temperature - Reduce the liquid temperature

- Increasing in noise level - Reduce the pressure drop before the

pump

- Reduce speed

Leaking shaft seal

- Dry run (See 4.1 Operation/control)

Replace: All wearing parts (See 5.1 General maintenance)

- Incorrect rubber grade If necessary:

- Change rubber grade

- Abrasive particles in the liquid

- Select stationary and rotating seal ring in Silicon Carbide/Silicon Carbide

Leaking seals Incorrect rubber grade Replace with seals of a different rubber

grade

4Operation

Danger, caustic!

Always wear rubber

gloves!

Always wear protective

goggles!

Noise measurements are carried out with the original motor and shroud, approximately at the Best Efficiency Point (BEP) with water at ambient temperature and at 50Hz.

Often, the noise level generated by the flow through the process system (e.g. valves, pipes, tanks etc.) is much higher that generated by the pump itself. Therefore, it is important to consider the noise level from the whole system and take any necessary precautions in terms of personal safety.
