available with standard motor, the inlet and outlet
are located at the pump bottom at the same plane
(inline type).
All pumps are equipped with a maintenance-free
mechanical seal set of the cartridge type.

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

 

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: 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.

 

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

 

 

This Vertical Multistage Water Pump of liquids with densities or kinematic viscosities higher than those of water will cause a consider-able pressure drop, a drop in the hydraulic performance and a rise in the power consumption.In such situations the pump should be fitted with a larger motor, if in doubt, contact Mislier.

From the Fig.3, the pump is installed at an altitude exc-eeding altitude 3500 meters,P2 will decrease to 83% if the ambient temperature is up to 70℃,P2 will decrease to 78%.
