Bell-Housing’s length calculation
Case A
Solution with monobloc bell-housing series LMC/LDC
Case B
Solution with low noise bell-housing series LMS/LDS
- H = 60 + 18 + 57.5 = 135.5 mm (18 = Sp spider - see page 31)
- Choose type of bell-housing (LMC - LMS):
For monobloc bell-housing LMC/LDC series see pages 75 ÷ 81
For Low noise bell-housing LMS/LDS series see pages 81 ÷ 89
For Multi-components 2-3 bell housing series see pages 91 ÷ 111
Note:
The length of bell-housing must be ≥ than the length calculated (135.5 mm)
- Electric motor power/motor size
- Manufacturer and pump type
1 - Pump and motor shaft dimensions (see electric motor data sheet)
2 - Shaft and ange pump (see pump data sheet)
Example:
- Electric motor 2.2 kW - size 100-112
- Atos pump code PFE31 - Shaft 1

Motor half-coupling (see page 26)
For IEC Electric motor size 100/112, the half-coupling is SGEA21M05060
Spider (see page 31)
For SGEA21, EGE2 - EGE2RR
(choose spider material on the base of the application, oil, temperature and cycle machine, etc.)
Pump half-coupling
Choose the drilling code - see pages 18-19 for shaft 19.05 - key 4.76 - code: G01
Pump half-coupling length = BH length - THK Spider - THK Spigot
LMC = 138 mm - 60 - 18 - 9.5 = 50.5 mm
LMS = 148 mm - 60 - 18 - 9.5 = 60.5 mm
LMC - Choose the half-coupling’s length at page 26 ≤ 50.5 mm.
LMS - Choose the half-coupling’s length at page 26 ≤ 60.5 mm.
LMC - Available length for SGEA21 = 50 mm
LMS - Available length for SGEA21 = 60 mm
Half coupling for LMC: SGEA21G01050
Half coupling for LMS: SGEA21G01050
Coupling selection
Note: for multi pumps we recommend to use a specic support on the base of the pump’s dimensions and weight.

GENERAL INFORMATION NOISE
THEORY AND DEFINITION OF NOISE
From a health and hygiene standpoint, noise can be dened as an unpleasant
and undesirable sound, or an unpleasant and annoying or intolerable auditory
sensation (noise being any sound phenomena that may be accompanied by
sensations of disturbance and pain). By definition, acoustic phenomena are
oscillatory in character, propagated in a exible medium and causing pressure
variations at the points, and the areas adjacent to those points, through which
they pass.
2
1
SOUND
Technically considered, certain elements must be present simultaneously
for acoustic phenomena to occur:
- Sound source
- Transmission medium
- Receive
The electric motor and the pump, together with the drive coupling, are the
SOURCE OF THE NOISE. The Bell-housing is the noise transmission MEDIUM.
Depending on whether the monobloc bell-housing is a rigid or low noise type,
there will be variations in the exible properties of the transmission medium.
The acoustic phenomena are dissimilar in the two cases, given the differences in
pressure variation and particle displacement.
MOTOR AND PUMP UNIT
Noise is a particularly pervasive problem so much so that there have been statutory regulations in place now for some years, designed to limit harmful
occupational exposure.
Many of the machines used in industry today are equipped with oil-hydraulic systems, which happen to be a major source of noise.

- Human ear
- Sound level meter

ASSEMBLY OF MOTOR AND PUMP UNIT
Low noise bell-housing will help to attenuate the transmission of vibrations and the emission of noise generated by the system.
Self-evidently, however, the mere adoption of a low noise bell-housing will achieve little unless the motor and pump are correctly installed on the machine
or on the tank of the hydraulic power unit.
Should be followed in order to achieve best possible results and correct installation:
1
MOTOR AND PUMP UNIT MOUNTED
HORIZONTALLY ON OIL TANK LID
- The suction pipe attached to the pump must be rigid and tted using a resilient
bulkhead flange of the FTA series, which helps to cushion the vibrations
propagated between the pipe and the tank lid.
If pipes need to be bent, the radius of curvature must be at least 3 times the
pipe diameter.
Do not use elbow ttings, as these will signicantly increase pressure losses.
- The pressure pipeline of the pump must be flexible and long enough to
include bends with the minimum radius of curvature recommended by the
manufacturer for the specied operating pressure.
- The return pipeline running from the service to the lter must be exible.
Where oil is returned directly to the tank of the hydraulic power unit through
a rigid pipe, it is advisable to use a resilient bulkhead ange of the FTR series,
which helps to cushion the vibrations propagated between the pipe and
the tank lid.
- Anti-vibration devices (resilient mounts or damping rods) must be located
under the feet of the electric motor or the PDM foot brackets, depending on
the mounting position of the motor.
- The lids of hydraulic oil tanks must be sturdy enough to support the load
they carry.
2
MOTOR AND PUMP UNIT MOUNTED
HORIZONTALLY ON MACHINE
- As a matter of good practice, the oil tank and motor-pump unit should be
mounted on a single supporting frame of strength sufcient to support the load.
- If the hydraulic system is tted with a side-mounted lter, the suction pipeline
to the pump must be flexible and long enough to include bends with the
minimum radius of curvature recommended by the manufacturer.
- If the suction filter is not side mounted, the pipeline should be rigid and
installed in conjunction with a compensating coupling.
- The pressure pipeline of the pump must be exible, and long enough to include
bends with the minimum radius of curvature recommended by the manufacturer
for the specied operating pressure.
- The return pipeline running from the service to the lter must be exible.
Where oil is returned directly to the tank of the hydraulic power unit through
a rigid pipe, it is advisable to use a resilient bulkhead ange of the FTR series,
which helps to cushion the vibrations propagated between the pipe
and the tank lid.
- Anti-vibration devices (resilient mounts or damping rods) must be located
under the feet of the electric motor or the PDM foot brackets, depending
on the mounting position of the motor.
FINAL CONSIDERATION
For best results, in any event, the motor-and-pump unit should be incorporated into the hydraulic system in such a way that no one component is rigidly associated
with another, resulting in the propagation of vibration, and consequently noise.
