Etaline
6.2.3.2 Density of the fluid handled
The pump input power changes in proportion to the density of the fluid handled.
CAUTION
Impermissibly high density of the fluid handled
Motor overload!
▷ Observe the information about fluid density in the data sheet.
▷ Make sure the motor has sufficient power reserves.
6.2.3.3 Abrasive fluids
The fluid handled may contain abrasive particles up to a maximum content of 5g/
dm³ and a maximum particle size of 0.5mm. When the pump handles fluids
containing abrasive substances, increased wear of the hydraulic system and the shaft
seal are to be expected. In this case, reduce the commonly recommended inspection
intervals.
6.3 Shutdown/storage/preservation
6.3.1 Measures to be taken for shutdown
The pump (set) remains installed
ü Sufficient fluid is supplied for the operation check run of the pump.
1. For prolonged shutdown periods, start up the pump (set) regularly between
once a month and once every three months for approximately five minutes.
ð This will prevent the formation of deposits within the pump and the pump
intake area.
The pump (set) is removed from the pipe and stored
ü The pump has been properly drained. (ðSection7.3,Page40)
ü The safety instructions for dismantling the pump have been observed.
(ðSection7.4.1,Page40)
1. Spray-coat the inside wall of the pump casing and, in particular, the impeller
clearance areas with a preservative.
2. Spray the preservative through the suction nozzle and discharge nozzle.
It is advisable to then close the pump nozzles (e.g. with plastic caps).
3. Oil or grease all exposed machined parts and surfaces of the pump (with
silicone-free oil or grease, food-approved if required) to protect them against
corrosion.
Observe the additional instructions on preservation. (ðSection3.3,Page13)
If the pump set is to be stored temporarily, only preserve the wetted components
made of low-alloy materials. Commercially available preservatives can be used for
this purpose. Observe the manufacturer's instructions for application/removal.
6.4 Returning to service
For returning the equipment to service observe the sections on commissioning/start-
up and the operating limits. (ðSection6.1,Page29) (ðSection6.2,Page32)
In addition, carry out all servicing/maintenance operations before returning the
pump (set) to service. (ðSection7,Page36)
