inflammable and non-explosive, not containing solid
particles or fibers.
Water supply&drainage for high-rise buildings,
filtration and transfer at waterworks, pressure boosting
in main pipe.
Washing and cleaning systems, boiler feeding, cooling
water circulation, water treatment systems, auxiliary
system, support equipment.
Ultra-filtration systems，reverse-osmosis systems，distillation
systems, separators, swimming pools.
Agricultural irrigation: sprinkler irrigation, drip-feed irrigation.
Food&beverage industry.
Fire-fighting system.
- Operating Conditions
Low viscosity, non-inflammable and non-explosive liquids
not containing solid particles or fibers. The liquids must not
chemically attack the pump materials. When pumping liquids
with a density or viscosity is higher than that of water, a motor
with a higher output power rating shall be used.
Liquid temperature：-20℃〜+ 120℃
Flow ranges: 0.7-240 m3/h
Liquid pH value：4-10
Max.ambient temperature：+ 40℃
Max. operation pressure: 33 bar
Altitude: up to 1000 m
- Motor
IE 2 motor (IE 3 motor optional)
Totally enclosed&fan-cooled
Protection class：IP55
Standard voltage ：50Hz 1×220V / 3×380V
- Ambient Temperature
Max.ambient temperature：+ 40℃.Ambient temperature
above 40℃or installation at altitude of more than 1000 meters
above sea level require the use of an oversize motor. Because
of low air density and poor cooling effects, the motor output
power P2 will be decreased. See the picture.
In such cases, it may be necessary to use a motor with a higher
output power rating.

Altitude: up to 1000 m
- Motor
Closed construction
Insulation class：F
Protection class: IP 55
IE 2 motor as standard.IE 3 motor is available on request
- Flange
EN 1092 and DIN 2576 standard
- Ambient Temperature
Max. Ambient temperature:+40°C.Ambient temperature above40°C,or
installation at altitude of more than 1000 m above sea level, require the
use of an oversize motor. Because of low air density and poor cooling
effects, the motor output power P2 will be decreased. See the picture.
For example, when the pump is installed at altitude of more than 3500 m
above sea level，P2 will be decrease to 88%.when the ambient
temperature is 70°C，P2 will be decreased to 78%.
