APPLICATION
QDL/QDLF is a kind of multifunctional products. It can be used to convey various medium from tap water to industrial liquid at different temperature and with different flow rate and pressure. QDL type is applicable to conveying non-corrosive liquid, While QDLF is suitable for slightly corrosive liquid.
Water supply: Water filter and transport in Waterworks, boosting of main pipeline, boosting in high-rise buildings.
Industrial boosting: Process flow water system, cleaning system, high-pressure washing system, fire fighting system
Industrial liquid conveying: Cooling and air-conditioning system, boiler water supply and condensing system, machine-associated purpose, acids and alkali
Water treatment: Ultrafiltration system, reverse osmosis system, distillation system, swimming pool, separator
Irrigation: Farmland irrigation, spray irrigation, dripping irrigation

Operation conditions
Thin, clean, non-flammable and non-explosive liquid containing no solid granules and fibers.
Liquid temperature:
Normal temperature type: -15C~+70 C
Hot water type: -15 C ~+120 C
Ambient temperature: Up to +40 C
Altitude: Up to 1000m

Pump
QDL/QDLF is a kind of vertical non-self priming multistage centrifugal pump, which is driven by a standard electric motor. The motor output shaft directly connects with the pump shaft through a co upling. The pressure-resistant cylinder and flow passage components are fixed between pump head and in-and outlet section with tie-bar bolts. The inlet and outlet are located at the pump bottom at the same plane. This kind of pump can be equipped with an intelligent protector to effectively prevent it from dry-running, out-of-phase and overload.
