Product Description
Product introduction
LQDLFD pumps are stainless steel light horizontal low-noise multi-stage centrifugal pumps .
The motor shafts are extended ones with a compact structure,so the pumps are very small.
Liquids flow into the pumps via the axial inlets and out the pumps via the radial outlets,ensuring stable running of the pumps.
The LQDLFD pumps are mainly used in:
Air-conditioning systems
Cooling systems
Flushing and cleaning systems
Water treatment systems
Aquaculture



Applications
Water supply:filtering,conveying,zoning based water supply,and main pipe pressurization of water plants,and pressurization of high-rise buildings
Industrial pressurization:process water systems,cleaning system,high-pressure flushing systems,and fire fighting systems.
Conveying of industrial liquids:cooling and air-conditioning systems,boiler water supply and condensation systems,supporting facilities of machines,acides,and alkalis.
Water treatment:ultrifiltration systems,reverse osmosis systems,distillation systems,separators,and swimming pools
Irrigation:farm irrigation,sprinkling irrigation,and drip irrigation
Operating conditions
Thin,clean,non-inflammable,non-explosive liquids containing neither solid particals nor fibers.
Liquid temperature:Room temperature type:-15ºC to +70ºC
Hot water type:+70ºC to +120ºC
Ambient temperature:+40ºC at most
Altitude:100m(this altitude would be the best)
Pumps
The LQDLFD pumps are stainless steel light vertical multi-stage centrifugal pumps characterized by high efficiency,low noise,compact structure,beautiful appearence,small volum,light weight,convenient operation and maintenance,reliable sealing performance,no secondary pollution for the conveyed liquids,slight corrosion resistance,etc. They may be provided with intelligent protectors as required to provide effective protection for their running without water,open-phase phenomenon,and overload.
