HVAC: Circulation of hot water, boiler mix-flow, temperature mix-flow,
intermittent heat supply, etc.
Air conditioning system: Cooling water circulation.
Water supply system: Filtration and transfer at waterworks;
Pressure boosting in main pipe.
Industrial applications: Washing& cleaning systems, boiler feeding,
cooling water circulation, water treatment systems, and auxiliary
Flow: up to 760 m3/h
Head: up to 85 m
Power range: 0.37 -132 kW
Max ambient temperature：+ 40°C
Max operation pressure: 16 bar
Altitude: up to 1000 m
Protection class: IP 55
IE 2 motor as standard.IE 3 motor is available on request
EN 1092 and DIN 2576 standard
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%.

systems, separators, swimming pools.
Agricultural irrigation: sprinkler irrigation, drip-feed irrigation.
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

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.
