Vertical Multi-Stage Centrifugal Pump

Pump connection mode
●Flange connection
●Threaded connection
●Clamp connection
●Oval flange connection

Pump material
●Cast iron
●Stainless steel (AISI304 ,AIS|316)
●Duplex stainless steel (2205)

Motor
●Squirrel cage fully enclosed air-cooled IEC motor, suitable for continuous operation
●Protection grade: IP55
●Insulation class: F
●Standard voltage: 3x220-240/380-415V 1x220- -240V
●Single-phase motors are available from 0.37kW- -2.2kW.

Pump liquid temperature
●Normal temperature pump: liquid temperature-15 ℃ to +70 ℃
●Hot water pump: liquid temperature -15 ℃ to +105 ℃ 

Performance curve
●All curves are based on motor measurements at a constant speed of 2900rpm or 2950rpm.
●Curve tolerance in line with ISO9906.
●Test using 20°C water without air, kinematic viscosity 1mm2 /s.
●The use of the pump refers to the performance range of the thick line to prevent the flow rate from overheating or excessive flow ambassador motor overload.

Pump operating condition
●Thin, clean, non-flammable and non-flammable liquid containing no particles or fibers (details can be found in the liquid delivery instructions at the end of the sample)
●Ambient temperature: no more than +40 ℃
●Altitude: no more than 1000m

Altitude and ambient temperature
When the pump is operating at an ambient temperature greater than 40° C or an altitude greater than 1000m, the motor output power P2 will be reduced, and the pump in the above cases, the motor power needs to be configured large.
