5.3 Storage
DANGER
Danger due to fluids hazardous to health!
If the pump is used in fluids hazardous to health, decontaminate the pump after dis-
mantling and before carrying out any other work! There is a risk of fatal injury! Ob-
serve the specifications in the work regulations! The operator must make sure that
the personnel have received and read the work regulations!
WARNING
Sharp edges on the impeller and suction port!
Sharp edges can form on the impeller and suction port. There is danger of limbs be-
ing severed! Protective gloves must be worn to protect from cuts.
CAUTION
Total damage due to moisture ingress
Moisture ingress in the power supply cable damages the power supply cable and the
pump! Never immerse the end of the power supply cable in a fluid and firmly seal it
during storage.
Newly supplied pumps can be stored for one year. Contact customer service to store
the pump for more than one year.
The following must be observed for storage:
ƒ
Place the pump upright (vertical) on a firm bearing surface and secure it against
slipping and falling over!
ƒ
The max. storage temperature is -15 °C to +60 °C (5 °F to 140 °F) at a max. relative
humidity of 90 %, non-condensing. Frost-proof storage at a temperature of 5 °C to
25 °C (41 °F to 77 °F) with relative humidity of 40 % to 50 % is recommended.
ƒ
Do not store the pump in rooms in which welding work is carried out. The resulting
gases or radiation can corrode the elastomer parts and coatings.
ƒ
Seal the suction and pressure connection tightly.
ƒ
Protect power supply cables against kinking and damage.
ƒ
Protect the pump from direct sunlight and heat. Extreme heat can cause damage to
the impellers and the coating!
ƒ
Impellers must be turned by 180 ° at regular intervals (3 – 6 months). This prevents
locking of the bearings and renews the lubrication film of the mechanical seal.
WARNING! There is a risk of injury due to sharp edges on the impeller and suction
port!
ƒ
Elastomer parts and the coating are subject to natural brittleness. Contact customer
service if the pump must be stored for more than 6 months.
After storage, remove any dust and oil from the pump and check the coating for dam-
age. Repair damaged coatings before further use.
