Handling of the bare shaft pump
To lift the pump, harness it as shown in the picture
Fig. 3
, by passing the ropes around the bearing supports.
Do not attach lifting devices to the shaft end of the pump. The angle of pull must not be greater than 90°
Handling of the complete set
Set with total load up to 1500 kg: Sling the group as in
Fig. 4
or, if present, use the holes or lifting pins made in the basement.
Set with total load higher than 1500 kg: it is not recomended to lift the complete set assembled. Lift the single components (pump, motor, coupling,
base). In case it is necessary to enliven the entire group, proceed like in
Fig. 4
.
Do not attach lifting devices to the shaft end of the pump or to the eybolts of the motor. The angle of pull must not be greater than
90°
STORING
WARNING!
Storage conditions: store the pump / set in a covered and dry place, lacking dust, freeze and vibrations.
Storage temperature= min 0°C - max 50°C
Metallic exposed surfaces (shaft ends, flanges) must be protected in a suitable way to prevent corrosion.
If you plan to store the pump or the complete set, for a long period of time (more than one month), it is necessary to perform the
following operations monthly:
•
verify that the preservation status of the pump / complete set and paying more attention to the non-painted surfaces;
•
check with the appropriate tools, the free rotation of the shaft;
•
check the condition of lubricating bearings.
•
Once a month, rotate shaft by hand, in order to keep the bearings protected by the lubricant.
•
For versions with oil lubricated bearings: fill the oil chamber to the brim. During the put on use, drain the oil and fill the
chamber up to the appropriate level.
For any problem replace or recondition the damages parts prior the use.
4. TECHNICAL SPECIFICATIONS AND USE
PRODUCT DESCRIPTION
NCB:
End-suction centrifugal pump with dimension according to EN733
NCBK:
End-suction centrifugal pump with dimension exceeding EN733
NCBZ / NCBKZ
: complete set with pump and motor coupled together by mean of an elastic coupling, on a base plate.
The pump / electric pump’s identification and technical data are listed on the name plate which certify the conformity to CE norms
(Fig. 1
). In case of pump
and motor assembled, a name plate will state for the hydraulic part and another one for the motor; in case of pumps sold without motor, there will be the
name plate with the hydraulic data only.
WARNING!
In case of a bare shaft pump, the useful output power provided by the motor must be above the power absorbed by the pump.
Do not use the pump for rotating speeds higher than those indicated on the data plate.
General technical features
End suction centrifugal single-stage pump (ESOB with axial suction)
“Back pull out” system: the hydraulic part can be removed without removing the pump body from the piping.
Horizontal or vertical installation (with suction downwards).
