Amarex KRT
Pump sets with cooling system (installation type K)
Pump sets with cooling system are suitable for continuous operation with the motor
outside the fluid .
Ready for operation The pump set is ready for operation when the minimum fluid level has been reached
(dimension B). Exact dimensions see general arrangement drawing/outline drawing.
NOTE
Compliance with dimension B does not guarantee trouble-free operation of the
pump set.
Depending on the pump's duty point, higher fluid levels may be required. Observe
the NPSH values indicated in the characteristic curve (see hydraulic characteristic
curves).
6.2.4.3 Density of the fluid handled
The power input of the pump changes in proportion to the density of the fluid
handled.
CAUTION
Impermissibly high density of fluid handled
Motor overload!
▷
Observe the information on fluid density in the data sheet.
▷ Make sure the motor has sufficient power reserves.
6.2.4.4 Abrasive fluids
Do not exceed the maximum permissible solids content specified in the data sheet.
When the pump handles fluids containing abrasive substances, increased wear of the
hydraulic system and the shaft seal is to be expected. In this case, halve the intervals
commonly recommended for servicing and maintenance.
6.3 Shutdown/storage/preservation
6.3.1 Measures to be taken for shutdown
The pump set remains installed
WARNING
Unintentional starting of pump set
Risk of injury by moving components and shock currents!
▷ Make sure that the pump set cannot be started up unintentionally.
▷
Always make sure the electrical connections are disconnected before carrying
out work on the pump set.
WARNING
Fluids handled, consumables and operating supplies which are hot or pose a health
hazard
Risk of personal injury!
▷ Observe all relevant laws.
▷
When draining the fluid take appropriate measures to protect persons and the
environment.
▷ Decontaminate pumps which handle fluids posing a health hazard.
