CVLA are non-self priming Vertical Multistage Water Pump, the pumps are
available with standard motor, the inlet and outlet
are located at the pump bottom at the same plane
(inline type).
Motor
Motor is totally enclosed, air-cooled two pole standard motor.
Protection grade: IP55
Insulation class: F
Motors of other voltages are available upon request.
Single phase motors are available from 0.37kw to 2.2kW
Standard voltage:
● 50Hz: 1x220-230/240V
● 3x200-220/346-380V
● 3x220-240/380-415V
● 3x380-415V
Motor Protection
Single-phase motor have a built-in thermal overload switch.
Three-phase motors must be connected to a motor
protective circuit breaker according to local regulations.
 
Ambient temperature
Ambient temperature: maximum+50℃ , if the ambient
temperature exceeds +50℃ , or the pump is installed
at an altitude exceeding 1000 meters, the motor must
not be fully loaded due to the risk of overheating.
Overheating may result from excessive ambient temperatures or the low density and consequently low
cooling effect of the air.
In such cases ,it may be necessary to use a motor with
a higher rated output.
 
Terminal box positions

As standard the terminal box is mounted on the suction side of the pump,meanwhile, 0°,90°,180°,270°could be adjusted according to the following proceeding:
1.lf necessary, disassembling the protective cover of the shaft connector, but did not disassembling the
shaft connector.
2.Disassembling the motor fixation screws.
3.Turn the motor to the required direction.
4.Fasten the motor screws.
5.Install the shaft connector's protective cover.The voltage and frequency are marked on the label.the correct power should be confirm with the label before usage.
To ensure the electric connection is conformity to the drawing marked on the label inside the terminal box
