This list shows specification of Ebara motors. In case of using other motors, please
see nameplate of motors and check the motor manufacturer's specification.
7.3 PUMP RATING PLATE
The nameplate is an aluminium label applied to the pump which bears its technical
specifications.
Relevant numbers:
"TYPE" Pump model
"P/N°" Pump item number
"Hmax" Maximum head
"Hmin" Minimum head
"Q" Indicates upper and lower flow rate limits
Indicates head limits corresponding to minimum and maximum
"H"
flow rate
"P2" Rated power of the motor (output at shaft)
"HP" Rated power of the motor expressed in HP (Horse Power)
"Hz" Frequency
"min-1" Speed of rotation
"MEI" Index of the pump's quality in relation to its efficiency
"Hyd. Eff." Hydraulic efficiency of the pump

8. PREPARING FOR USE
WARNING!
Installation must be carried out by a qualified 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 EVMS pumps must meet IEC standards and must
have the preload spring positioned as illustrated:
WARNING!
Required the presence and the installation of the
preload spring as indicated in the drawing above.
