LPP
- Application
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
systems.
Fire-fighting system. - Pump
Flow: up to 760 m3/h
Head: up to 85 m
Power range: 0.37 -132 kW
Liquid temperature:0°C-+90°C
Max ambient temperature：+ 40°C
Max operation pressure: 16 bar
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%.
