This list shows specication of Ebara motors. In case of using other
motors, please see nameplate of motors and check the motor
manufacturer’s specication.
7.3. PUMP RATING PLATE
The nameplate is an aluminium label applied to the pump which bears its
technical specications.
Relevant numbers:
1) “TYPE” Pump model
2) “Q” Indicates upper and lower ow rate limits
3) “H”
Indicates head limits corresponding to minimum and
maximum ow rate
4) “Hmax” Maximum head
5) “Hmin” Minimum head
6) “P2” Rated power of the motor (output at shaft)
7) “HP”
Rated power of the motor expressed in HP (Horse
Power)
8) “Hz” Frequency
9) “min-1” Speed of rotation
10) “P/N°” Pump item number
11) “N” Material code
12) “MEI” Index of the pump’s quality in relation to its efciency
13) “Hyd. Eff. ” Hydraulic efciency of the pump

8. PREPARING FOR USE
WARNING!
Installationmustbecarriedoutbyaqualiedengineer.
Free the pump from the packaging and lift it and lower it
with suitable lifting gear in compliance with safety rules.
Note that the motor’s lifting hooks are not suitable for
lifting the motor-driven pump.
8.1 COUPLING TO THE MOTOR
The motors to be coupled to the EVM pumps must meet IEC standards and
must have the preload spring positioned as illustrated:
