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 corrosive liquid, While QDLF is suiable for slightly corrosive liquid.

Water supply: water filter and transport in waterworks, boosting of main pipeline, boosting in high-rise building.

Industrial liquid conveying: cooling and air-condition system, boiler water supply and condensing system, machine-associated purpose, acids and alkali.

Industrial boosting: process flow water system, cleaning system, high-pressure washing system, fire fighting system.

Water treatment: ulrafitation system, reverse osmosis system, distillation system, separator, swimming pool.

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 type: -15°C~+70°C

Hot water type: +70°C~+120°C

Ambient temperature: up to +40°C

Altitude: up to 1000m

Pump

QDL/F 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 coupling. 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 quipped with an intelligent protector to effectively prevent it from dry- running, out-of- phase and overload.
