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 specic support on the base of the pump’s dimensions and weight.

GENERAL INFORMATION
SGE SERIES
Admissible misalignment radial, angular and axial
Standard ATEX Directive 2014/34/EU and UK Regulation S.I. 2016 No. 1107 (as amended)
MP Filtri couplings are developed with:
The half-couplings series SGE*** allow secure transmission between the electric
motor and the driven side; they are able to absorb shocks and vibration, in
addition to compensating radial misalignment, angular and axial.
The assembly of the couplings can be horizontal/vertical, withstanding vibration
and load reversals.
The complete range of couplings are extrapolated from the on-line software, with
a length equal than the shaft on which must be mounted and they are completed
with grub screw for xing located on the key.
Available for cylindrical shaft with metric and imperial dimensions as well for
splined shafts as per specication DIN, ISO and SAE.
Half-couplings are available to use in hazardous area.
The couplings are certied according to Standard ATEX Directive 2014/34/EU and
UK Regulation S.I. 2016 No. 1107 (as amended) - Category certied 2G - Area 1 and 2.

Examples verication of the coupling
Select the half-coupling of the calculated size from the motor half-couplings table.
Note: When selecting the coupling, remember that for pumps with splined shaft, only cast iron couplings of the SGEG series can be used.

Mt: 9560 x kW / rpm = Nm
Me > Mt x S = Nm
Where:
Mt: Torque transmitted by electric motor
Me: Torque transmitted by coupling
kW: Power of electric motor
Rpm: Revolutions per minute of electric motor
S: Service factor
Example
Electric motor, 4 pole - 4 kW
hydraulic pump, uniform load, low operating pressure
Mt: 9560 x 4 / 1500 = 25.45 Nm
Me > 25.49 x 1.3 = 33 Nm
Half-coupling SGEA21 meets the above requirement.
Torque transmitted by electric motor:
Table 1
Determine the size of the coupling according to the type of installation and application envisaged, on the basis of the formulas and the following tables:
Nominal and maximum torque values are referred to couplings assembled with standard exible spiders of the EGE** series (see page 31).
Where higher torques are to be transmitted, use exible spiders of the EGE**RR series (see page 31).
