Technicalspecifications And Use; Construction Features - SAER Elettropompe TM Serie Manual De Empleo Y Mantenimiento

To lift the pump, harness it as shown in the picture Fig. 7, 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. 8-9 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. 8-9.
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
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:
•
WARNING!
•
•
•
•
For any problem replace or recondition the damages parts prior the use.
4. TECHNICAL SPECIFICATIONS AND USE
PRODUCT DESCRIPTION
Centrifugal multistage horizontal (TM-TMB) or vertical (TMV) pumps and electric pumps, driven by elastic or hydro-dynamic coupling. The pumps in the
TM series can be connected to electric, Diesel, hydraulic engines or turbines whose revs are within a range of 1450 and 3500.
TM: Multistage horizontal pump with axial suction (Fig.1)
TMB: Multistage horizontal pump with radial suction (Fig.2)
TMV: Multistage vertical pump with radial suction ( Fig.3)
TMZ / TMBZ / TMVZ: complete set with pump and motor coupled together by mean of an elastic coupling, on a base plate (Fig.4-5).
The pump / electric pump's identification and technical data are listed on the name plate which certify the conformity to CE norms (Fig. 6). 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.

CONSTRUCTION FEATURES

Suction body with axial (TM) or radial (TMB,TMV) inlet; intermediate stage composed of stage body and corresponding diffuser with replaceable
wearing rings. Delivery body with upward (TM,TMB) or radial (TMV) outlet, with the possibility of turning in at 90° in both directions. Drive side bearing
support with high rigidity. Suction side support of sliding type, lubricated by the pumped liquid. (TMB:double support). Shaft in stainless steel completely
protected. Adjustable packing seal on the shaft, in alternative not balanced or balanced mechanical seal, according to the working pressure. External tie
rods for tightening of the intemediate stages.
For motor features refer to motor's manual.
USE – STANDARD VERSIONS
Pumping of clean liquids and without solid bodies , for civil , industrial and agricultural uses. Use the pump / electric pump only for the purposes described
in this manual. Any other use can be a cause of accidents.
For the special versions, refer to the specific technical literature (technical data, drawings, etc. ...).
Limitation for use
Passing of solids: max 2 mm.
Max working time with closed delivery: 2 min.
Temperature of the pumped liquid: min -15°C max 120°C (90° with soft-packing, standard).
Max starts / h equally distributed: Refer to the motor instruction manual
Maximum working pressure: refer to pump name plate
Max ambient temperature: 40°C
For applications in firefighting equipment follow all the requirements of the UNI 12845 or applicable local regulations.
Keep the manual for future reference - For more informations visit www.saerelettropompe.com
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.
